o3-deep-research is failed with the status incomplete with the reason as content filter
I working on an to do an deep research on internal data. I'm using currently the Azure OpenAI Responses API with MCP Tool. The underlying MCP server deployed into ACA with search and fetch tool with signatures in complaint with the specification (https://developers.openai.com/apps-sdk/build/mcp-server#company-knowledge-compatibility). OpenAI client created with 03-deep-research model with MCP tool, in a loop response status being checked. (https://learn.microsoft.com/en-us/azure/foundry/openai/how-to/deep-research#remote-mcp-server-with-deep-research) Deep Research is being carried out for sometime, I could see in the log that handshake has been made, ListTools invoked, search tool is called post that fetch is called for the queries framed by the model.. But intermittently, the response status is becoming "incomplete" with incomplete reason as "content_filter". Otherwise the deep research is working fine. Not able identify the root cause as there is seems to be no way to identify what caused the content filtration whether its the prompt or completion. How to debug and check the root cause and rectify this ? Or is there known issue with the o3-deep-research model's intermediate reasoning completions Or search and fetch tool results are causing this ? I had uploaded a file made it available to MCP server, the search and fetch tool uses an Azure OpenAI agent to search the data using File Search and fetch tool gets the content of the file based on the id passed. For same file and same research topic the issue is not occurring always but intermittently.
GPT-5.5-Pro not listed in foundry?
The model is mentioned in this blog post : https://azure.microsoft.com/en-us/blog/openais-gpt-5-5-in-microsoft-foundry-frontier-intelligence-on-an-enterprise-ready-platform/ But it is currently not listed on Foundry. Only latest pro model is 5.4-pro. When will 5.5-pro model be available on azure foundry?Migrating to GPT-5.x Without Breaking GPT-4: A Practical, Backward-Compatible Playbook
The first request your service sends after swapping gpt-4o for gpt-5.1 in production will return HTTP 400. Not in two weeks. On the first call. And the parameter the error points to isn't one you set anywhere in your code - it's bound onto the request by a LangChain helper you've used for two years. This post walks through every breaking change between the GPT-4 and GPT-5 families on Azure OpenAI in Microsoft Foundry, the integration cliffs nobody warns you about, and the small set of files you need so the same call sites work against both model families without branching. Who this is for: engineers maintaining an existing production codebase that calls Azure OpenAI / OpenAI - directly or through LangChain - and needs to onboard GPT-5.x while keeping the GPT-4 deployments alive during rollout. What you'll leave with: one copy-paste compatibility module, a tiny LangChain subclass, a prompt-audit harness, and a 10-step rollout checklist. 1. Why this migration is different Every previous Azure OpenAI bump - 3.5 → 4, 4 → 4o, 4o → 4o-mini - was additive. You changed engine="gpt-4o" and everything kept working. GPT-5.x is the first generation that is subtractive: parameters you used to send now return 400 Unsupported parameter. The wire protocol itself changed because GPT-5 is a reasoning model - it spends tokens thinking internally before it answers, so the parameters that controlled the old sampling pipeline (temperature, top_p, presence_penalty, frequency_penalty) no longer exist on the request schema. What this means for production code: A passing test suite against gpt-4o will fail on the first call against gpt-5.1 with HTTP 400. A passing test suite against gpt-5.1 will fail on every legacy gpt-4* deployment because the new reasoning controls (reasoning_effort, verbosity) are not recognised there. LangChain helpers that worked unmodified for two years (notably create_sql_query_chain) silently bind stop=[...] onto your LLM and trigger the same 400. Source-grep won't find the offending line because it lives inside the library. The good news: the divergence is mechanical. With one detection helper, one parameter-builder, and one tiny LangChain subclass you can run the same code against both families. 2. The breaking-changes matrix Concern GPT-4 / GPT-4o (legacy) GPT-5.x / o1 / o3 (reasoning) Output budget max_tokens max_completion_tokens (rejects max_tokens) temperature 0.0–1.0 Only the default (1) is accepted - omit it top_p Supported Rejected presence_penalty, frequency_penalty Supported Rejected logprobs, logit_bias Supported Rejected stop sequences Supported Rejected on most reasoning deployments reasoning_effort Rejected New: minimal | low | medium | high verbosity Rejected New: low | medium | high (sometimes via extra_body) System instruction role system developer recommended; system still works as alias Output token cost Output tokens only Output + reasoning tokens count against your cap Recommended API version 2024-12-01-preview or earlier 2025-03-01-preview or later Two consequences are easy to miss: max_completion_tokens is a shared budget. GPT-5.1 can burn 2–4× more tokens internally before emitting the first response token. A cap of 4096 that comfortably held a SQL query on GPT-4o now silently truncates the answer mid-token on GPT-5.1. Multiply your legacy budgets by ~2.5× and add a floor (e.g. 4096) before sending. The stop parameter is the silent killer. Any helper that calls llm.bind(stop=[...]) - and there are several in langchain - will turn a working code path into a 400 the moment you swap deployments. 3. Compatibility strategy: detect, don't fork The temptation is to fork: one branch for GPT-4, one for GPT-5. Don't. The right unit of abstraction is one function that classifies the deployment into a family, and one function that builds a kwargs dict the SDK will accept for that family. Every call site - SDK, LangChain, raw HTTP - drains into the same kwargs builder. When you eventually retire GPT-4 you delete the legacy branch in one file, not in fifty. 4. The industry-agnostic compatibility module Drop the following file into your project. It has no Azure / OpenAI / LangChain imports at module load time, so the same file works from a web service, a serverless function, a notebook, or a CLI tool. 4.1 model_compat.py """ Model compatibility helper for GPT-5.x with GPT-4 backward compatibility.

The second LangChain gotcha: prose where SQL should be create_sql_query_chain is documented to return the literal string "I don't know" (or a similar fallback) when the LLM cannot form a query. The default code path takes the chain output and runs it against the database: sql = chain.invoke({...}) # -> "I don't know" result = db.run(sql) # -> sends "I don't know" to pyodbc The database faithfully returns: [42000] Unclosed quotation mark after the character string 't know'. (105) Which surfaces to the end user as a misleading "SQL syntax error". The mitigation is a one-line guard that validates the chain output looks like SQL before execution: import re _SQL_START_RE = re.compile( r"^\s*(?:WITH|SELECT|INSERT|UPDATE|DELETE|CREATE|DROP|ALTER|MERGE|EXEC|EXECUTE|TRUNCATE)\b", re.IGNORECASE, ) def looks_like_sql(text: str) -> bool: """True only if ``text`` starts with a recognised SQL DML/DDL keyword.""" if not text or not text.strip(): return False return bool(_SQL_START_RE.match(text)) sql = extract_sql_query(chain.invoke({...})) if not looks_like_sql(sql): logging.warning("SQL chain returned a non-SQL response: %r", sql[:200]) return ( "I couldn't form a SQL query for that question. " "Please rephrase or add more context." ) result = db.run(sql) This isn't specific to GPT-5.1 - it's good hygiene for any LLM that backs a SQL agent - but the failure mode becomes much more frequent on reasoning models because they're better at refusing. 7. Cleaning Markdown out of create_sql_query_chain output Reasoning models like to wrap their answer in a markdown fence and append a "Note:" or "Explanation:" paragraph. None of that survives db.run(). A defensive extract_sql_query handles all the variants: import re def extract_sql_query(text: str) -> str: """Strip markdown fences, leading prose, and trailing explanations.""" # 1) Prefer SQL inside a markdown code fence. m = re.search(r"```(?:sql|SQL|Sql)?\s*\n(.*?)\n```", text, re.DOTALL) if m: text = m.group(1) text = text.strip() # 2) Drop any prose *before* the SQL by jumping to the first SQL keyword. m = re.search( r"(?im)^\s*(WITH|SELECT|INSERT|UPDATE|DELETE|CREATE|DROP|ALTER|MERGE|EXEC|EXECUTE|TRUNCATE)\b", text, ) if m: text = text[m.start(1):] # 3) Cut at the first "Explanation:" / "Note:" / "This query..." marker. m = re.compile( r"(?im)^\s*(?:Explanation|Note|Notes|Here(?:'|\u2019)?s|" r"This\s+(?:query|SQL|statement|returns|counts|selects|will|gets|finds)|" r"The\s+(?:query|SQL|above|result|statement)|" r"Result|Results|Description|Output|Answer)\b[^\n]*" ).search(text) if m: text = text[: m.start()].rstrip() # 4) Drop any trailing fence that survived step 1. if text.endswith("```"): text = text[:-3].rstrip() return text.strip() 8.

New GPT-5.x knobs worth using Once you're on a reasoning deployment, two new parameters become available. Both are optional, both default to a sensible value, and both are stripped by the kwargs builder above when the target is a legacy model. reasoning_effort minimal - one-shot lookups, classification. low - deterministic structured output (SQL, JSON-schema extraction, rule-based rewrites). Lowest cost overhead. medium (default) - RAG, summarisation, normal Q&A. high - multi-step analytical reasoning, complex code synthesis. A useful pattern is to choose the level by task profile rather than at the call site: TASK_EFFORT = { "sql": "low", "structured_extract": "low", "kg_cleaning": "low", "rag_qa": "medium", "vision": "medium", "analytical": "high", } verbosity low | medium | high. Controls the length of the response, not its substance. Useful for grounding chat UIs where you want crisp answers - set low for /answer endpoints and high for "explain like a senior engineer" panels. Note: in openai-python <= 1.65.x, verbosity is not yet a top-level keyword argument; pass it through extra_body (the builder above already does this). developer role GPT-5.x prefers {"role": "developer", "content": "..."} for instructions that previously used system. The change is non-breaking on the Azure side - system is still accepted as an alias - but some downstream LangChain prompt templates predate the role and will reject it on construction. Treat developer as opt-in (OPENAI_USE_DEVELOPER_ROLE=1) for now; flip the default after your prompt-template version is known good. 10. Auditing your existing prompts When the wire-level migration is done your service will talk to GPT-5.x - but that doesn't mean it says the right thing. Reasoning models read prompts differently in ways that won't show up as 400s: They take instructions more literally. A prompt that worked when GPT-4o rounded the corners may surface every edge case verbatim. They refuse more often. "I don't know" / "I cannot help with that" are more frequent because reasoning models are less willing to confabulate. They ignore "be concise" / "be terse". Use the new verbosity knob. Step-by-step / chain-of-thought instructions become redundant. The model already reasons internally; extra "think before you answer" prose competes with its own chain of thought and often hurts output quality. Negative-only instructions can backfire. "Never output X" prompts occasionally cause refusals where you'd rather have a workaround. 10.1 Build a prompt regression harness Capture every system+user prompt your service emits in a CSV, then replay each one against both deployments and diff the output. The diff is the single most useful artefact you can produce before the cutover: # prompt_audit.py - minimal differential tester import csv from openai import AzureOpenAI from model_compat import build_openai_chat_kwargs LEGACY = "gpt-4o" REASONING = "gpt-5.1" client = AzureOpenAI( azure_endpoint=os.environ["AZURE_OPENAI_ENDPOINT"], api_version=os.environ["OPENAI_API_VERSION"], api_key=os.environ["AZURE_OPENAI_API_KEY"], ) def run(model: str, system: str, user: str) -> str: kw = build_openai_chat_kwargs( model=model, max_tokens=4096, temperature=0.2, # auto-dropped for reasoning reasoning_effort="medium", # auto-dropped for legacy ) resp = client.chat.completions.create( messages=[ {"role": "system", "content": system}, {"role": "user", "content": user}, ], **kw, ) return resp.choices[0].message.content or "" with open("prompts.csv") as f_in, open("diff.tsv", "w", newline="") as f_out: writer = csv.writer(f_out, delimiter="\t") writer.writerow(["id", "legacy_first80", "reasoning_first80", "len_legacy", "len_new", "identical"]) for row in csv.DictReader(f_in): legacy = run(LEGACY, row["system"], row["user"]) new = run(REASONING, row["system"], row["user"]) writer.writerow([ row["id"], legacy[:80].replace("\n", " "), new[:80].replace("\n", " "), len(legacy), len(new), legacy.strip() == new.strip(), ]) Capture three signals per prompt - they're enough to triage 95% of drift: Format compliance. Did the output still parse as the expected JSON / YAML / Markdown / SQL? Run your existing downstream parser on both columns. Token cost delta. Reasoning models tend to be more verbose by default. Anything beyond +20% is a candidate for the verbosity="low" knob. Semantic drift. Spot-check 5–10% of rows by hand. You're looking for changes in intent, not changes in wording. 10.2 Common rewrites to make prompts model-agnostic The goal isn't to write two prompts. It's to write one prompt that produces correct output on both families by moving constraints out of the natural-language body and into the request shape. 10.2a. Format constraints belong in response_format, not the prose Don't: Output ONLY a JSON object with keys `name` and `score`. Do not include any explanation. Do not wrap in markdown. Do not say anything else. Do: resp = client.chat.completions.create( messages=[...], response_format={ "type": "json_schema", "json_schema": { "name": "scored_entity", "schema": { "type": "object", "properties": { "name": {"type": "string"}, "score": {"type": "number"}, }, "required": ["name", "score"], "additionalProperties": False, }, "strict": True, }, }, **kw, ) response_format is honoured by both gpt-4o (>= 2024-08-06) and the entire GPT-5.x line. The prompt loses three lines of brittle natural-language constraints and you get schema-validated output for free. 10.2b. Replace "think step by step" with reasoning_effort Don't: Let's think step by step. First identify the entity. Then find the category. Then compute the score. Then format the answer. Do: delete the prose and pass reasoning_effort="medium" (or "high") for reasoning deployments. The kwargs builder drops the parameter automatically for GPT-4 models, so the same prompt now produces: step-by-step reasoning internally on GPT-5.x (lower output token cost), the same final answer on GPT-4o that the verbose prompt used to elicit. 10.2c. Replace temperature-based variety with n sampling If your code relied on temperature=0.9 to get diverse completions, GPT-5.x will return roughly the same answer every time. Generate variety the explicit way: resp = client.chat.completions.create(messages=[...], n=5, **kw) candidates = [c.message.content for c in resp.choices] Or call the model N times with slightly different framings. Both patterns work against either family with no further code changes. 10.2d. Move procedural instructions to the developer role For multi-step workflows, the new developer role gives clearer separation between what the system enforces and what the user is asking: messages = [ {"role": get_system_role(deployment), "content": role_card_for_assistant}, {"role": "developer", "content": procedural_instructions}, {"role": "user", "content": user_question}, ] get_system_role returns "system" for legacy models and "developer" for reasoning models opted in via OPENAI_USE_DEVELOPER_ROLE=1. Once your LangChain templates support the new role you can flip the default. 10.2e. Add a literal-execution header for strict formats For prompts where the exact output shape matters (table generation, SQL with a fixed column order, structured incident reports), prepend an explicit literal-execution header so reasoning models don't drift into "helpful improvements": LITERAL_EXECUTION_HEADER = ( "Execution mode: follow the instructions below literally and in order. " "Do not infer intent, skip, reorder, merge, or add steps. Honour the " "exact formatting, tone, and verbosity specified. If a step is " "ambiguous, respond with the literal interpretation and flag the " "ambiguity instead of guessing." ) def apply_literal_execution(prompt: str) -> str: if LITERAL_EXECUTION_HEADER in prompt: return prompt return f"{LITERAL_EXECUTION_HEADER}\n\n{prompt}" It's a no-op on GPT-4o (the older models already follow instructions literally enough) and a meaningful guard rail on GPT-5.1. Wire it behind an OPENAI_LITERAL_EXECUTION flag so you can disable it without redeploying. 10.3 A prompt-shaped checklist Run every prompt your service emits past these questions: Question Action Does it specify output format in prose? Move to response_format (10.2a) Does it include "think step by step"? Remove; set reasoning_effort (10.2b) Does it set tone constraints ("be concise")? Use verbosity Does it use negative-only instructions ("never X")? Add positive alternative ("do Y instead") Does it embed example outputs with values that would change? Replace concrete values with placeholder tokens (<VALUE>) Does it rely on temperature > 0 for variety? Use n=K sampling (10.2c) Is the system prompt > 2k tokens? Split into role-card (system) + procedure (developer) Does output ordering matter? Add the literal-execution header (10.2e) 10.4 Score before you ship Don't approve a rewritten prompt by eyeballing one example. Score it: Format compliance rate. Percentage of N=50 outputs that pass your existing downstream parser / JSON schema validation. Token cost delta. Cap regression at +20% versus the legacy baseline. Beyond that, dial verbosity="low" or tighten the prompt. Latency p50 / p95 delta. Reasoning models add tail latency. If your SLA is tight, set reasoning_effort="low" for the path or move it to a background queue. A prompt that regresses on any of those by more than your tolerance window ships behind a feature flag with rollback wired in. 11. Testing strategy Two test layers catch >90% of regressions: Family-classification tests import pytest from model_compat import get_model_family, build_openai_chat_kwargs @pytest.mark.parametrize("name,expected", [ ("gpt-5.1", "reasoning"), ("gpt5", "reasoning"), ("gpt-5-prod-eu", "reasoning"), ("o3-mini", "reasoning"), ("o1", "reasoning"), ("gpt-4o", "legacy"), ("gpt-4", "legacy"), ("gpt-4-32k", "legacy"), ("gpt-35-turbo", "legacy"), ("", "legacy"), # unknown -> fail closed to legacy (None, "legacy"), ]) def test_family(name, expected): assert get_model_family(name) == expected def test_kwargs_for_reasoning_drops_temperature(): kw = build_openai_chat_kwargs( model="gpt-5.1", max_tokens=1000, temperature=0.2, top_p=0.9, reasoning_effort="low", ) assert "temperature" not in kw assert "top_p" not in kw assert kw["max_completion_tokens"] >= 4096 # floor applied assert kw["reasoning_effort"] == "low" def test_kwargs_for_legacy_keeps_temperature(): kw = build_openai_chat_kwargs( model="gpt-4o", max_tokens=1000, temperature=0.2, top_p=0.9, ) assert kw["max_tokens"] == 1000 assert kw["temperature"] == 0.2 assert kw["top_p"] == 0.9 assert "reasoning_effort" not in kw Wire-level smoke tests For each LLM call site you maintain, write a single integration test that exercises the chain against a real (or mocked) endpoint and asserts: HTTP 200, non-empty content, finish_reason != "length" (so you catch silent truncation), (optional) classifier-style assertions against a golden output. Run those tests once against the legacy deployment and once against the new one - same test code, two OPENAI_ENGINE values. 12. Things that don't change It's easy to over-correct. Several pieces of plumbing keep working without modification: Authentication. AAD token providers, managed identity, and API keys are unchanged. Embeddings. text-embedding-3-small, text-embedding-3-large, and text-embedding-ada-002 are not part of the reasoning generation; the embeddings call shape is identical. Function calling / tool use. Same JSON schema, same response shape. Streaming. SSE format is unchanged. Token counters. tiktoken still works, but bump to 0.8.0+ so the new model name resolves to the right encoding instead of silently falling back to cl100k_base. 13. Next steps If you only do four things from this post, do these - in order: Deploy a GPT-5.1 model side-by-side with your current GPT-4 deployment in Microsoft Foundry. Keep the GPT-4 deployment live; you'll need both for the parallel-run period. Drop model_compat.py and langchain_compat.py into your project (Sections 4 and 5). Replace every AzureChatOpenAI(...) construction with ReasoningSafeAzureChatOpenAI and route every kwargs literal through the builders. Run the prompt-audit harness (Section 10.1) against your top 50 most frequently invoked prompts. Triage the diff with the checklist in 10.3. Roll out behind a percentage-based flag. Start at 5% of traffic for 24 hours, compare quality and cost telemetry against the GPT-4o baseline, then ramp.

Data Visualisation / Charting in Azure Foundry
Hi Foundry community, We are working on an agent that can query internal data sources, and are looking for ways that we can visualise data (think pie charts, bar charts, etc.). This would be consumed by end users through Copilot/Teams. However we are unable to find a way to do so, which is surprising given that you easily can create charts through M365 Copilot Chat and through Copilot Studio. We have tried using the 'Code Interpreter' tool, but the Teams/Copilot client UIs just do not render the results inline, either interactive or as an embedded image. They also do not give any option to download them. Has anyone tackled this before? How have you been able generate charts? Many thanks!From RAG to agents: Build AI pipelines inside Azure HorizonDB
By Abe Omorogbe, Navya Teja Gajula, Binnur Gorer, B Harsha Kashyap, Krishnakumar Ravi (KK) from Microsoft PostgreSQL AI team If you’ve ever shipped a RAG app, this will feel familiar. Your data lives in Postgres. But the pipeline that turns that data into vectors lives somewhere else, spread across external services, queues, and retry logic. And when the embedding API hiccups mid-batch? That’s a 2 a.m. production incident. You didn’t set out to build your own embedding service. You just wanted to search your documents. And RAG is only the beginning. The moment AI works on your data: extraction, summarization, reranking, keeping embeddings fresh, or powering agent, you’re back to stitching together more services, queues, and glue code, all outside the database. AI pipelines in Azure HorizonDB (Preview) removes that entire stack. Define your workflows steps like chunking, embeding, extracting, and generating in SQL, and HorizonDB runs them as AI pipelines next to your data. No orchestrator. No glue code. Just Postgres. In this post we'll cover: The external-orchestrator issue that every AI on Postgres team eventually hits What AI pipelines are, and the four-part anatomy that makes them click Use cases worth trying: semantic search, knowledge extraction, content generation, smarter reranking, and always-fresh embeddings How to watch your pipelines run as live graphs in VS Code How to spin up HorizonDB and run your first pipeline today 🚀 Try it on Azure HorizonDB. AI pipelines are built into Microsoft's new PostgreSQL cloud service, no extra infrastructure to stand up. Write ai.create_pipeline(...), call ai.run(...), and it runs. Get started in HorizonDB → AI preprocessing runs outside the database, far from your data The standard way to get data into a vector store looks reasonable on a whiteboard: a service reads source rows, calls an embedding API, and writes chunks back to Postgres. However, some interesting issues often occur in production. The embedding API fails mid-batch, and there's no shared checkpoint showing which rows were completed. You rerun the job, and the extra API calls increases cost. A worker crashes after writing chunks but before flipping the parent row's processed flag. Now your embeddings are quietly inconsistent, and nobody knows. Every one of these is the same missing primitive: durable, checkpointed execution that lives where your data lives. External orchestrators can do it, but now you're operating a second service just to feed the first one. AI pipelines move that logic into HorizonDB itself. The source, the steps, the sink, and the full run history are all SQL protected by the same transactions, backups, and point-in-time restore your data already has. The database is already where your data commits. It's a natural place for the pipeline to live too. Anatomy of an AI pipeline in HorizonDB are optional and can be adjusted as needed. A pipeline has four parts: Source: where rows come from. A table_source(...) over a HorizonDB table, optionally with an incremental_column so the pipeline skips rows it already processed. Steps: the AI operations that transform each row, in order. Each step appends columns to the in-flight batch. Sink: where results land, ready for use by your AI apps or agent. Trigger: 'on_change' (run automatically when source rows change) or 'manual' (run only when you call ai.run()). Those four parts give the pipeline its shape. The steps are where you define the AI work itself, using composable building blocks: Step What it does ai.chunk() Split long text into overlapping chunks ai.embed() Generate vector embeddings ai.extract() Pull structured fields out of text with an LLM ai.generate() Generate text from a prompt (i.e content generation, classify, summarize and more) ai.rank() Score documents against a query How the pieces fit together. The ai.* API gives you the AI pipeline shape: sources define where data comes from, steps define the AI work to perform, sinks define where results land, and triggers define when the pipeline runs. Under the covers, HorizonDB turns that definition into a durable execution graph, where each step can be checkpointed, retried, and resumed if something fails. Built on open source. That durability isn't magic, every AI pipeline compiles down to a graph that runs on pg_durable, Microsoft's open-source durable-execution engine for PostgreSQL (built on the duroxide Rust runtime). The ai.* API is the AI-shaped surface (sources, steps, sinks, triggers) and pg_durable is the general-purpose engine underneath that handles checkpointing, retries, and crash recovery. So, your pipelines stand on a transparent, inspectable foundation you can read, and run on any Postgres 17 & 18. No black box, no lock-in. Use case 1: Semantic search over your data This is one of the most popular use cases. Turn a table of documents into searchable vectors, durably, and keep them fresh as the data changes. That last part matters: in production, documents are edited, added, and deleted constantly, and every change needs the right chunks and embeddings updated without reprocessing the entire corpus or leaving stale vectors behind. With AI pipelines, HorizonDB can track those incremental updates for you. Chunk the body, embed each chunk, and land the result in a DiskANN-indexed table. -- Define the pipeline: source -> chunk -> embed -> sink. SELECT ai.create_pipeline( name => 'rag_pipeline', source => ai.table_source(table_name => 'documents'), steps => ARRAY[ ai.chunk(input => 'content', chunk_size => 512, overlap => 64), ai.embed(model => 'default-embedding', input => 'chunk_text', dimensions => 1536) ], trigger => 'on_change', -- re-embed automatically as rows change sink => ai.table_sink('rag_pipeline_output') ); -- Run it SELECT ai.run('rag_pipeline'); -- Search your data SELECT chunk_text, embedding <=> azure_openai.create_embeddings('text-embedding-3-small', 'how does vector search work?')::vector AS distance FROM rag_pipeline_output ORDER BY distance LIMIT 3; 📘 Read more details in the AI Pipelines documentation That's the entire ingestion layer; chunking, embedding, checkpointing, retries, and sink writes in one definition. Because trigger => 'on_change', the pipeline updates embeddings whenever source rows change, processing only what is new or modified instead of redoing the whole corpus. Your vectors stay in sync with your data, and your ingestion work stays efficient as the dataset grows. Point a query at the DiskANN index and you've got production semantic search without a single line of application glue. That's the whole loop: define, run, inspect. The embedding service you were about to build the queue, the workers, the retry logic, the checkpoint table, the 2 a.m. production incident doesn't happens. Why it's better than an external service: a failure in ai.embed() never re-runs ai.chunk(), each step is a durable node. If the database restarts mid-run, it resumes from the last checkpointed batch, not row zero. Use case 2: Turn unstructured text into structured metadata Support tickets, contracts, product reviews, research papers are full of structure that's locked inside unstructured documents. ai.extract() pulls named fields out of text and merges them into the metadata JSONB column, so you can filter and aggregate on things an LLM read for you. SELECT ai.create_pipeline( name => 'extraction_pipeline', source => ai.table_source(table_name => 'documents'), steps => ARRAY[ ai.chunk(input => 'content'), ai.extract( input => 'chunk_text', data => ARRAY['topics: string - the main topics discussed', 'entities: string - named people, products, or places'] model => 'my-gpt' -- optional, the default model when AI model management is activate ) ], sink => ai.table_sink('extraction_pipeline_output') ); SELECT ai.run('extraction_pipeline'); -- Now query the structured fields the LLM extracted: SELECT doc_id, metadata->'topics' AS topics, metadata->'entities' AS entities FROM extraction_pipeline_output; 📘 Read more details in the AI Pipelines documentation You describe each field as a label: description string in the ai.extract step, and HorizonDB does the rest durably, in bulk, with the same retry-and-resume guarantees. Each field is a label, either a bare name like product, or the detailed form name: type - description (for example `sentiment: number - sentiment score from 1 to 5`). HorizonDB does the rest, durably, in bulk, with the same retry-and-resume guarantees. Use case 3: Summarize and rewrite content at scale ai.generate() runs an LLM prompt against every row, perfect for bulk summarization, classification, tone normalization, or generating titles. Because it's a pipeline, "summarize 4 million documents" becomes a job that survives restarts instead of a script you have to monitor overnight. SELECT ai.create_pipeline( name => 'summary_pipeline', source => ai.table_source(table_name => 'documents'), steps => ARRAY[ ai.chunk(input => 'content'), ai.generate( input => 'chunk_text', system_prompt => 'Create a concise summary in 50 words or fewer.' model => 'my-gpt' -- optional, the default model when AI model management is activate ) ], sink => ai.table_sink('generation_pipeline_output') ); SELECT ai.run('summary_pipeline'); -- Now query the generated text: SELECT doc_id, left(generated_text, 100) AS summary_preview FROM generation_pipeline_output WHERE generated_text IS NOT NULL LIMIT 5; 📘 Read more details in the AI Pipelines documentation Swap the system_prompt and the same shape becomes a classifier ("Label this ticket as billing, bug, or feature request"), a translator, or a headline generator. The instruction goes in system_prompt; the result lands in generated_text. Use case 4: Keep embeddings fresh, and re-embed cleanly when the model changes This is where AI pipelines become especially useful. In a real AI app, two things change constantly: your data and your model. AI pipelines are designed to handle both changes directly. Your data changes. Set incremental_column and an on_change trigger, and the pipeline only embeds new or changed rows, automatically, forever, until you pause or drop it. SELECT ai.create_pipeline( name => 'rag_pipeline', source => ai.table_source( table_name => 'documents', incremental_column => 'updated_at' -- only process what changed ), steps => ARRAY[ ai.chunk(input => 'content'), ai.embed(model => 'default-embedding', input => 'chunk_text', dimensions => 1536) ], trigger => 'on_change', sink => ai.table_sink('rag_pipeline_output') ); Your model changes. Bump the model or the dimensions, then run a single, resumable backfill, no migration script, no babysitting: TRUNCATE rag_pipeline_output; SELECT ai.backfill('rag_pipeline'); 📘 Read more details in the AI Pipelines documentation The backfill runs as one durable instance. If the database restarts mid-backfill, it picks up from the last checkpointed batch instead of starting over. The painful "re-embed everything" migration becomes a one-liner you can actually trust. Watch your pipelines run as live graphs in VS Code A pipeline you can see is a pipeline you can trust. Install the PostgreSQL extension for VS Code, connect to HorizonDB, then right-click your database and open Pipelines & Workflows → AI Pipelines. Select any run and the center pane renders the execution as a color-coded graph: Blue 🔵 : source and sink (where data enters and exits) Green 🟢 : processing steps (chunk, embed, extract, generate, rank) Pink 🟣 : external model and service calls For each run you can read the status (completed, running, failed), the run ID for traceability, start time and duration for performance, and a link back to the pipeline definition.

Foundry Agent deployed to Copilot/Teams Can't Display Images Generated via Code Interpreter
Hello everyone, I’ve been developing an agent in the new Microsoft Foundry and enabled the Code Interpreter tool for it. In Agent Playground, I can successfully start a new chat and have the agent generate a chart/image using Code Interpreter. This works as expected in both the old and new Foundry experiences. However, after publishing the agent to Copilot/Teams for my organization, the same prompt that works in Agent Playground does not function properly. The agent appears to execute the code, but the image is not accessible in Teams. When reviewing the agent traces (via the Traces tab in Foundry), I can see that the agent generates a link to the image in the Code Interpreter sandbox environment, for example: `[Download the bar chart](sandbox:/mnt/data/bar_chart.png)` This works correctly within Foundry, but the sandbox path is not accessible from Teams, so the link fails there. Is there an officially supported way to surface Code Interpreter–generated files/images when the agent is deployed to Copilot/Teams, or is the recommended approach perhaps to implement a custom tool that uploads generated files to an external storage location (e.g., SharePoint, Blob Storage, or another file hosting service) and returns a publicly accessible link instead? I've been having trouble finding anything about this online. Any guidance would be greatly appreciated. Thank you!FPGA vs ASIC for AI at the Edge: What factors influence your hardware choice?
As AI continues to move closer to edge devices, choosing the right hardware platform has become an important design decision. While both FPGAs and ASICs have their strengths, the best choice often depends on the application's requirements. Here are some of the key factors that engineering teams typically evaluate: Performance and latency requirements Power efficiency Development cost and NRE Time-to-market Production volume Need for future hardware updates FPGAs offer flexibility for rapid prototyping and evolving workloads, making them well-suited for early-stage development. ASICs, on the other hand, can provide significant advantages in performance, power consumption, and cost efficiency for high-volume production. I recently came across a technical article that explains these trade-offs in a structured way and found it useful as a reference: https://www.signoffsemiconductors.com/asic-vs-fpga/ I'd be interested to hear how others approach this decision. Have you migrated a design from FPGA to ASIC? What factors influenced your choice? Are there workloads where you would always choose one over the other?
Weird problem when comparing the answers from chat playground and answer from api
I'm running into a weird issue with Azure AI Foundry (gpt-4o-mini) and need help. I'm building a chatbot that classifies each user message into: follow-up to previous message repeat of an earlier message brand-new query The classification logic works perfectly in the Azure AI Foundry Chat Playground. But when I use the exact same prompt in Python via: AzureChatOpenAI() (LangChain) or the official Azure OpenAI code from "View Code" (client.chat.completions.create()) …I get totally different and often wrong results. I’ve already verified: same deployment name (gpt-4o-mini) same temperature / top_p / max_tokens same system and user messages even tried copy-pasting the full system prompt from the Playground But the API version still behaves very differently. It feels like Azure AI Foundry’s Chat Playground is using some kind of hidden system prompt, invisible scaffolding, or extra formatting that is NOT shown in the UI and NOT included in the “View Code” snippet. The Playground output is consistently more accurate than the raw API call. Question: Does the Chat Playground apply hidden instructions or pre-processing that we can’t see? And is there any way to: view those hidden prompts, or replicate Playground behavior exactly through the API or LangChain? If anyone has run into this or knows how to get identical behavior outside the Playground, I’d really appreciate the help.

What You Will Build By the end of this guide, you will have a working multi-agent system where 4 specialist AI agents collaborate to diagnose production issues: ClientAnalyst — Analyzes browser, JavaScript, CORS, uploads, and UI symptoms NetworkAnalyst — Analyzes DNS, TCP/IP, TLS, load balancers, and firewalls ServerAnalyst — Analyzes backend logs, database, deployments, and resource limits Coordinator — Synthesizes all findings into a root cause report with a prioritized action plan These agents don't just run in sequence — they debate, cross-examine, and challenge each other's findings through a shared conversation, producing a diagnosis that's better than any single agent could achieve alone. Table of Contents Why Multi-Agent? The Problem with Single Agents Architecture Overview Understanding the Key SK Components The Actor Model — How InProcessRuntime Works Setting Up Your Development Environment Step-by-Step: Building the Multi-Agent Analyzer The Agent Interaction Flow — Round by Round Bugs I Found & Fixed — Lessons Learned Running with Different AI Providers What to Build Next 1. Why Multi-Agent? The Problem with Single Agents A single AI agent analyzing a production issue is like having one doctor diagnose everything — they'll catch issues in their specialty but miss cross-domain connections. Consider this problem: "Users report 504 Gateway Timeout errors when uploading files larger than 10MB. Started after Friday's deployment. Worse during peak hours." A single agent might say "it's a server timeout" and stop. But the real root cause often spans multiple layers: The client is sending chunked uploads with an incorrect Content-Length header (client-side bug) The load balancer has a 30-second timeout that's too short for large uploads (network config) The server recently deployed a new request body parser that's 3x slower (server-side regression) The combination only fails during peak hours because connection pool saturation amplifies the latency No single perspective catches this. You need specialists who analyze independently, then debate to find the cross-layer causal chain. That's what multi-agent orchestration gives you. The 5 Orchestration Patterns in SK Semantic Kernel provides 5 built-in patterns for agent collaboration: SEQUENTIAL: A → B → C → Done (pipeline — each builds on previous) CONCURRENT: ↗ A ↘ Task → B → Aggregate ↘ C ↗ (parallel — results merged) GROUP CHAT: A ↔ B ↔ C ↔ D ← We use this one (rounds, shared history, debate) HANDOFF: A → (stuck?) → B → (complex?) → Human (escalation with human-in-the-loop) MAGENTIC: LLM picks who speaks next dynamically (AI-driven speaker selection) We use GroupChatOrchestration with RoundRobinGroupChatManager because our problem requires agents to see each other's work, challenge assumptions, and build on each other's analysis across two rounds. 2. Architecture Overview Here's the complete architecture of what we're building: 3. Understanding the Key SK Components Before we write code, let's understand the 5 components we'll use and the design pattern each implements: ChatCompletionAgent — Strategy Pattern The agent definition. Each agent is a combination of: name — unique identifier (used in round-robin ordering) instructions — the persona and rules (this is the prompt engineering) service — which AI provider to call (Strategy Pattern — swap providers without changing agent logic) description — what other agents/tools understand about this agent agent = ChatCompletionAgent( name="ClientAnalyst", instructions="You are ONLY ClientAnalyst...", service=gemini_service, # ← Strategy: swap to OpenAI with zero changes description="Analyzes client-side issues", ) GroupChatOrchestration — Mediator Pattern The orchestration defines HOW agents interact. It's the Mediator — agents don't talk to each other directly. Instead, the orchestration manages a shared ChatHistory and routes messages through the Manager. RoundRobinGroupChatManager — Strategy Pattern The Manager decides WHO speaks next. RoundRobinGroupChatManager cycles through agents in a fixed order. SK also provides AutomaticGroupChatManager where the LLM decides who speaks next. max_rounds is the total number of messages per agent or cycle. With 4 agents and max_rounds=8, each agent speaks exactly twice. InProcessRuntime — Actor Model Abstraction The execution engine. Every agent becomes an "actor" with its own kind of mailbox (message queue). The runtime delivers messages between actors. Key properties: No shared state — agents communicate only through messages Sequential processing — each agent processes one message at a time Location transparency — same code works in-process today, distributed tomorrow agent_response_callback — Observer Pattern A function that fires after EVERY agent response. We use it to display each agent's output in real-time with emoji labels and round numbers. 4. The Actor Model — How InProcessRuntime Works The Actor Model is a concurrency pattern where each entity is an isolated "actor" with a private mailbox. Here's what happens inside InProcessRuntime when we run our demo: runtime.start() │ ├── Creates internal message loop (asyncio event loop) │ orchestration.invoke(task="504 timeout...", runtime=runtime) │ ├── Creates Actor[Orchestrator] → manages overall flow ├── Creates Actor[Manager] → RoundRobinGroupChatManager ├── Creates Actor[ClientAnalyst] → mailbox created, waiting ├── Creates Actor[NetworkAnalyst] → mailbox created, waiting ├── Creates Actor[ServerAnalyst] → mailbox created, waiting └── Creates Actor[Coordinator] → mailbox created, waiting Manager receives "start" message │ ├── Checks turn order: [Client, Network, Server, Coordinator] ├── Sends task to ClientAnalyst mailbox │ → ClientAnalyst processes: calls LLM → response │ → Response added to shared ChatHistory │ → callback fires (displayed in Notebook UI) │ → Sends "done" back to Manager │ ├── Manager updates: turn_index=1 ├── Sends to NetworkAnalyst mailbox │ → Same flow... │ ├── ... (ServerAnalyst, Coordinator for Round 1) │ ├── Manager checks: messages=4, max_rounds=8 → continue │ ├── Round 2: same cycle with cross-examination │ └── After message 8: Manager sends "complete" → OrchestrationResult resolves → result.get() returns final answer runtime.stop_when_idle() → All mailboxes empty → clean shutdown The Actor Model guarantees: No race conditions (each actor processes one message at a time) No deadlocks (no shared locks to contend for) No shared mutable state (agents communicate only via messages) 5.

The Agent Interaction Flow — Round by Round Here's what actually happens during the 8-message orchestration: Round 1: Independent Analysis (Messages 1-4) Msg Agent What They See What They Do 1 ClientAnalyst Problem statement only Analyzes from client perspective: upload chunking, progress bar freezing at 85%, CORS, content-type headers 2 NetworkAnalyst Problem + ClientAnalyst's analysis Gives INDEPENDENT analysis despite seeing msg 1: load balancer timeouts, proxy body size limits, TCP window scaling 3 ServerAnalyst Problem + msgs 1-2 Gives INDEPENDENT analysis: recent deployment regression, request body parser, thread pool exhaustion, disk space 4 Coordinator Problem + msgs 1-3 Observes patterns: "All three mention timeout configuration. ClientAnalyst and NetworkAnalyst both point to body size. Question: Was the deployment a backend-only change or did it include infra?" Round 2: Cross-Examination (Messages 5-8) Msg Agent What They Do 5 ClientAnalyst "I agree with NetworkAnalyst that the load balancer timeout is likely a factor — the 85% freeze point matches the 30-second LB timeout for a 10MB upload on our average upload speed. However, I disagree with ServerAnalyst about thread pool exhaustion because the UI shows a clean 504, not a connection reset." 6 NetworkAnalyst "ServerAnalyst's point about the recent deployment is critical — if the new request parser is 3x slower, that would push uploads past the LB timeout. I can confirm the LB has a 30s idle timeout. The fix is both: increase LB timeout AND optimize the parser." 7 ServerAnalyst "Responding to Coordinator's question: The deployment was backend-only — a new multipart parser using streaming instead of buffered reads. ClientAnalyst is correct that the 504 is from the LB, not the app. The app itself returns 200 after 45 seconds, but the LB kills the connection at 30." 8 Coordinator Produces final structured report with root cause: "The backend deployment introduced a slower multipart parser (45s vs 15s for 10MB). The load balancer's 30s timeout kills the connection at ~85% progress. Fix: immediate — increase LB timeout to 120s. Short-term — optimize parser. Long-term — implement chunked uploads with progress resumption." Notice: The Round 2 analysis is dramatically better than Round 1. Agents reference each other by name, build on each other's findings, and the Coordinator can synthesize a cross-layer causal chain that no single agent could have produced. I made a small adjustment to the issue with Azure Web Apps. Please find the details below from testing carried out using Google Gemini: 8. Bugs I Found & Fixed — Lessons Learned Building this demo taught me several important lessons about multi-agent systems: Bug 1: Agents Speaking Only Once Symptom: Only 4 messages instead of 8. Root cause: The agents list was missing the Coordinator. It was defined in a separate cell and wasn't included in the members list. Fix: All 4 agents must be in the same list passed to GroupChatOrchestration. Bug 2: NetworkAnalyst Says "I'm Ready to Proceed" Symptom: NetworkAnalyst's Round 2 response was just "I'm ready to proceed with the analysis" — no actual content. Root cause: The Coordinator's Round 1 message was assigning tasks ("NetworkAnalyst, please check the load balancer config"), and the agent was acknowledging the assignment instead of analyzing. Fix: Added explicit constraint to Coordinator: "Round 1 MUST NOT assign tasks — observation + questions ONLY." Bug 3: ServerAnalyst Says "As NetworkAnalyst, I..." Symptom: ServerAnalyst's response started with "As NetworkAnalyst, I believe..." Root cause: LLM identity bleeding. When agents share ChatHistory, the LLM sometimes loses track of which agent it's currently playing. This is especially common with Gemini. Fix: Identity anchoring at the very top of every agent's instructions: "You are ONLY ServerAnalyst. You must NEVER speak as ClientAnalyst, NetworkAnalyst, or Coordinator." Bug 4: Gemini Gives Thin/Empty Responses Symptom: Some agents responded with just one sentence or "I concur." Root cause: Gemini 2.5 Flash is more concise than GPT-4o by default. Without explicit length requirements, it takes shortcuts. Fix: Added "Every response MUST be at least 200 words" and "Answer the Coordinator's questions" to every specialist's instructions. Bug 5: Coordinator's Report is 18K Characters Symptom: The Coordinator's Round 2 response was absurdly long — repeating everything every specialist said. Fix: Added word limits: "Round 1 max 300 words, Round 2 max 800 words" and "Synthesize, don't echo." Bug 6: MAX_ROUNDS Math Symptom: With MAX_ROUNDS=9, ClientAnalyst spoke a 3rd time after the Coordinator's final report — breaking the clean 2-round structure. Fix: MAX_ROUNDS must equal (number of agents × number of rounds). For 4 agents × 2 rounds = 8. 9. Running with Different AI Providers The beauty of SK's Strategy Pattern is that you change ONE LINE to switch providers. Everything else — agents, orchestration, callbacks, validation — stays identical. Gemini setup: from semantic_kernel.connectors.ai.google.google_ai import GoogleAIChatCompletion service = GoogleAIChatCompletion( gemini_model_id="gemini-2.5-flash", api_key=os.getenv("GOOGLE_AI_API_KEY"), ) OpenAI Setup from semantic_kernel.connectors.ai.open_ai import OpenAIChatCompletion service = OpenAIChatCompletion( ai_model_id="gpt-4o", api_key=os.getenv("OPEN_AI_API_KEY"), ) 10. What to Build Next Add Plugins to Agents Give agents real tools — not just LLM reasoning - looks exciting right ;) class NetworkDiagnosticPlugin: (description="Pings a host and returns latency") def ping(self, host: str) -> str: result = subprocess.run(["ping", "-c", "3", host], capture_output=True, text=True) return result.stdout class LogSearchPlugin: (description="Searches server logs for error patterns") def search_logs(self, pattern: str, hours: int = 1) -> str: # Query your log aggregator (Splunk, ELK, Azure Monitor) return query_logs(pattern, hours) Add Filters for Governance Intercept every agent call for PII redaction and audit logging: .filter(filter_type=FilterTypes.FUNCTION_INVOCATION) async def audit_filter(context, next): print(f"[AUDIT] {context.function.name} called by agent") await next(context) print(f"[AUDIT] {context.function.name} returned") Try Different Orchestration Patterns Replace GroupChat with Sequential for a pipeline approach: # Instead of debate, each agent builds on the previous orchestration = SequentialOrchestration( members=[client_agent, network_agent, server_agent, coordinator_agent] ) Or Concurrent for parallel analysis: # All specialists analyze simultaneously, Coordinator aggregates orchestration = ConcurrentOrchestration( members=[client_agent, network_agent, server_agent] ) Deploy to Azure Move from InProcessRuntime to Azure Container Apps for production scaling. The agent code doesn't change — only the runtime. Summary The key insight from building this demo: multi-agent systems produce better results than single agents not because each agent is smarter, but because the debate structure forces cross-domain thinking that a single prompt can never achieve. The Coordinator's final report consistently identifies causal chains that span client, network, and server layers — exactly the kind of insight that production incident response teams need. Semantic Kernel makes this possible with clean separation of concerns: agents define WHAT to analyze, orchestration defines HOW they interact, the manager defines WHO speaks when, the runtime handles WHERE it executes, and callbacks let you OBSERVE everything. Each piece is independently swappable — that's the power of SK from Microsoft.
