How Do We Know AI Isn’t Lying? The Art of Evaluating LLMs in RAG Systems
🔍 1. Why Evaluating LLM Responses is Hard In classical programming, correctness is binary. Input Expected Result 2 + 2 4 ✔ Correct 2 + 2 5 ✘ Wrong Software is deterministic — same input → same output. LLMs are probabilistic. They generate one of many valid word combinations, like forming sentences from multiple possible synonyms and sentence structures. Example: Prompt: "Explain gravity like I'm 10" Possible responses: Response A Response B Gravity is a force that pulls everything to Earth. Gravity bends space-time causing objects to attract. Both are correct. Which is better? Depends on audience. So evaluation needs to look beyond text similarity. We must check: ✔ Is the answer meaningful? ✔ Is it correct? ✔ Is it easy to understand? ✔ Does it follow prompt intent? Testing LLMs is like grading essays — not checking numeric outputs. 🧠 2. Why RAG Evaluation is Even Harder RAG introduces an additional layer — retrieval. The model no longer answers from memory; it must first read context, then summarise it. Evaluation now has multi-dimensions: Evaluation Layer What we must verify Retrieval Did we fetch the right documents? Understanding Did the model interpret context correctly? Grounding Is the answer based on retrieved data? Generation Quality Is final response complete & clear? A simple story makes this intuitive: Teacher asks student to explain Photosynthesis. Student goes to library → selects a book → reads → writes explanation. We must evaluate: Did they pick the right book? → Retrieval Did they understand the topic? → Reasoning Did they copy facts correctly without inventing? → Faithfulness Is written explanation clear enough for another child to learn from? → Answer Quality One failure → total failure. 🧩 3. Two Types of Evaluation 🔹 Intrinsic Evaluation — Quality of the Response Itself Here we judge the answer, ignoring real-world impact. We check: ✔ Grammar & coherence ✔ Completeness of explanation ✔ No hallucination ✔ Logic flow & clarity ✔ Semantic correctness This is similar to checking how well the essay is written. Even if the result did not solve the real problem, the answer could still look good — that’s why intrinsic alone is not enough. 🔹 Extrinsic Evaluation — Did It Achieve the Goal? This measures task success. If a customer support bot writes a beautifully worded paragraph, but the user still doesn’t get their refund — it failed extrinsically. Examples: System Type Extrinsic Goal Banking RAG Bot Did user get correct KYC procedure? Medical RAG Was advice safe & factual? Legal search assistant Did it return the right section of the law? Technical summariser Did summary capture key meaning? Intrinsic = writing quality. Extrinsic = impact quality. A production-grade RAG system must satisfy both. 📏 4. Core RAG Evaluation Metrics (Explained with Very Simple Analogies) Metric Meaning Analogy Relevance Does answer match question? Ask who invented C++? → model talks about Java ❌ Faithfulness No invented facts Book says started 2004, response says 1990 ❌ Groundedness Answer traceable to sources Claims facts that don’t exist in context ❌ Completeness Covers all parts of question User asks Windows vs Linux → only explains Windows Context Recall / Precision Correct docs retrieved & used Student opens wrong chapter Hallucination Rate Degree of made-up info “Taj Mahal is in London” 😱 Semantic Similarity Meaning-level match “Engine died” = “Car stopped running” 💡 Good evaluation doesn’t check exact wording. It checks meaning + truth + usefulness. 🛠 5. Tools for RAG Evaluation 🔹 1. RAGAS — Foundation for RAG Scoring RAGAS evaluates responses based on: ✔ Faithfulness ✔ Relevance ✔ Context recall ✔ Answer similarity Think of RAGAS as a teacher grading with a rubric. It reads both answer + source documents, then scores based on truthfulness & alignment. 🔹 2. LangChain Evaluators LangChain offers multiple evaluation types: Type What it checks String or regex Basic keyword presence Embedding based Meaning similarity, not text match LLM-as-a-Judge AI evaluates AI (deep reasoning) LangChain = testing toolbox RAGAS = grading framework Together they form a complete QA ecosystem. 🔹 3. PyTest + CI for Automated LLM Testing Instead of manually validating outputs, we automate: Feed preset questions to RAG Capture answers Run RAGAS/LangChain scoring Fail test if hallucination > threshold This brings AI closer to software-engineering discipline. RAG systems stop being experiments — they become testable, trackable, production-grade products. 🚀 6. The Future: LLM-as-a-Judge The future of evaluation is simple: LLMs will evaluate other LLMs. One model writes an answer. Another model checks: ✔ Was it truthful? ✔ Was it relevant? ✔ Did it follow context? This enables: Benefit Why it matters Scalable evaluation No humans needed for every query Continuous improvement Model learns from mistakes Real-time scoring Detect errors before user sees them This is like autopilot for AI systems — not only navigating, but self-correcting mid-flight. And that is where enterprise AI is headed. 🎯 Final Summary Evaluating LLM responses is not checking if strings match. It is checking if the machine: ✔ Understood the question ✔ Retrieved relevant knowledge ✔ Avoided hallucination ✔ Provided complete, meaningful reasoning ✔ Grounded answer in real source text RAG evaluation demands multi-layer validation — retrieval, reasoning, grounding, semantics, safety. Frameworks like RAGAS + LangChain evaluators + PyTest pipelines are shaping the discipline of measurable, reliable AI — pushing LLM-powered RAG from cool demo → trustworthy enterprise intelligence.

Building High-Performance Agentic Systems
Most enterprise chatbots fail in the same quiet way. They answer questions. They impress in demos. And then they stall in production. Knowledge goes stale. Answers cannot be audited. The system cannot act beyond generating text. When workflows require coordination, execution, or accountability, the chatbot stops being useful. Agentic systems exist because that model is insufficient. Instead of treating the LLM as the product, agentic architecture embeds it inside a bounded control loop: plan → act (tools) → observe → refine The model becomes one component in a runtime system with explicit state management, safety policies, identity enforcement, and operational telemetry. This shift is not speculative. A late-2025 MIT Sloan Management Review / BCG study reports that 35% of organizations have already adopted AI agents, with another 44% planning deployment. Microsoft is advancing open protocols for what it calls the “agentic web,” including Agent-to-Agent (A2A) interoperability and Model Context Protocol (MCP), with integration paths emerging across Copilot Studio and Azure AI Foundry. The real question is no longer whether agents are coming. It is whether enterprise architecture is ready for them. This article translates “agentic” into engineering reality: the runtime layers, latency and cost levers, orchestration patterns, and governance controls required for production deployment. The Core Capabilities of Agentic AI What makes an AI “agentic” is not a single feature—it’s the interaction of different capabilities. Together, they form the minimum set needed to move from “answering” to “operating”. Autonomy – Goal-Driven Task Completion Traditional bots are reactive: they wait for a prompt and produce output. Autonomy introduces a goal state and a control loop. The agent is given an objective (or a trigger) and it can decide the next step without being micromanaged. The critical engineering distinction is that autonomy must be bounded: in production, you implement it with explicit budgets and stop conditions—maximum tool calls, maximum retries, timeouts, and confidence thresholds. The typical execution shape is a loop: plan → act → observe → refine. A project-management agent, for example, doesn’t just answer “what’s the status?” It monitors signals (work items, commits, build health), detects a risk pattern (slippage, dependency blockage), and then either surfaces an alert or prepares a remediation action (re-plan milestones, notify owners). In high-stakes environments, autonomy is usually human-in-the-loop by design: the agent can draft changes, propose next actions, and only execute after approval. Over time, teams expand the autonomy envelope for low-risk actions while keeping approvals for irreversible or financially sensitive operations. Tool Integration – Taking Action and Staying Current A standalone LLM cannot fetch live enterprise state and cannot change it. Tool integration is how an agent becomes operational: it can query systems of record, call APIs, trigger workflows, and produce outputs that reflect the current world rather than the model’s pretraining snapshot. There are two classes of tools that matter in enterprise agents: Retrieval tools (grounding / RAG)When the agent needs facts, it retrieves them. This is the backbone of reducing hallucination: instead of guessing, the agent pulls authoritative content (SharePoint, Confluence, policy repositories, CRM records, Fabric datasets) and uses it as evidence. In practice, retrieval works best when it is engineered as a pipeline: query rewrite (optional) → hybrid search (keyword + vector) → filtering (metadata/ACL) → reranking → compact context injection. The point is not “stuff the prompt with documents,” but “inject only the minimum evidence required to answer accurately.” Action tools (function calling / connectors) These are the hands of the agent: update a CRM record, create a ticket, send an email, schedule a meeting, generate a report, run a pipeline. Tool integration shifts value from “advice” to “execution,” but also introduces risk—so action tools need guardrails: least-privilege permissions, input validation, idempotency keys, and post-condition checks (confirm the update actually happened). In Microsoft ecosystems, this tool plane often maps to Graph actions + business connectors (via Logic Apps/Power Automate) + custom APIs, with Copilot Studio (low code) or Foundry-style runtimes (pro code) orchestrating the calls. Memory (Context & Learning) – Context Awareness and Adaptation “Memory” is not just a long prompt. In agentic systems, memory is an explicit state strategy: Working memory: what the agent has learned during the current run (intermediate tool results, constraints, partial plans). Session memory: what should persist across turns (user preferences, ongoing tasks, summarized history). Long-term memory: enterprise knowledge the agent can retrieve (indexed documents, structured facts, embeddings + metadata). Short-term memory enables multi-step workflows without repeating questions. An HR onboarding agent can carry a new hire’s details from intake through provisioning without re-asking, because the workflow state is persisted and referenced. Long-term “learning” is typically implemented through feedback loops rather than real-time model weight updates: capturing corrections, storing validated outcomes, and periodically improving prompts, routing logic, retrieval configuration, or (where appropriate) fine-tuning. The key design rule is that memory must be policy-aware: retention rules, PII handling, and permission trimming apply to stored state as much as they apply to retrieved documents. Orchestration – Coordinating Multi-Agent Teams Complex enterprise work is rarely single-skill. Orchestration is how agentic systems scale capability without turning one agent into an unmaintainable monolith. The pattern is “manager + specialists”: an orchestrator decomposes the goal into subtasks, routes each to the best tool or sub-agent, and then composes a final response. This can be done sequentially or in parallel. Employee onboarding is a classic: HR intake, IT account creation, equipment provisioning, and training scheduling can run in parallel where dependencies allow. The engineering challenge is making orchestration reliable: defining strict input/output contracts between agents (often structured JSON), handling failures (timeouts, partial completion), and ensuring only one component has authority to send the final user-facing message to avoid conflicting outputs. In Microsoft terms, orchestration can be implemented as agentic flows in Copilot Studio, connected-agent patterns in Foundry, or explicit orchestrators in code using structured tool schemas and shared state. Strategic Impact – How Agentic AI Changes Knowledge Work Agentic AI is no longer an experimental overlay to enterprise systems. It is becoming an embedded operational layer inside core workflows. Unlike earlier chatbot deployments that answered isolated questions, modern enterprise agents execute end-to-end processes, interact with structured systems, maintain context, and operate within governed boundaries. The shift is not about conversational intelligence alone; it is about workflow execution at scale. The transformation becomes clearer when examining real implementations across industries. In legal services, agentic systems have moved beyond document summarization into operational case automation. Assembly Software’s NeosAI, built on Azure AI infrastructure, integrates directly into legal case management systems and automates document analysis, structured data extraction, and first-draft generation of legal correspondence. What makes this deployment impactful is not merely the generative drafting capability, but the integration architecture. NeosAI is not an isolated chatbot; it operates within the same document management systems, billing systems, and communication platforms lawyers already use. Firms report time savings of up to 25 hours per case, with document drafting cycles reduced from days to minutes for first-pass outputs. Importantly, the system runs within secure Azure environments with zero data retention policies, addressing one of the most sensitive concerns in legal AI adoption: client confidentiality. JPMorgan’s COiN platform represents another dimension of legal and financial automation. Instead of conversational assistance, COiN performs structured contract intelligence at production scale. It analyzes more than 12,000 commercial loan agreements annually, extracting over 150 clause attributes per document. Work that previously required approximately 360,000 human hours now executes in seconds. The architecture emphasizes structured NLP pipelines, taxonomy-based clause classification, and private cloud deployment for regulatory compliance. Rather than replacing legal professionals, the system flags unusual clauses for human review, maintaining oversight while dramatically accelerating analysis. Over time, COiN has also served as a knowledge retention mechanism, preserving institutional contract intelligence that would otherwise be lost with employee turnover. In financial services, the impact is similarly structural. Morgan Stanley’s internal AI Assistant allows wealth advisors to query over 100,000 proprietary research documents using natural language. Adoption has reached nearly universal usage across advisor teams, not because it replaces expertise, but because it compresses research time and surfaces insights instantly. Building on this foundation, the firm introduced an AI meeting debrief agent that transcribes client conversations using speech-to-text models and generates CRM notes and follow-up drafts through GPT-based reasoning. Advisors review outputs before finalization, preserving human judgment. The result is faster client engagement and measurable productivity improvements. What differentiates Morgan Stanley’s approach is not only deployment scale, but disciplined evaluation before release. The firm established rigorous benchmarking frameworks to test model outputs against expert standards for accuracy, compliance, and clarity. Only after meeting defined thresholds were systems expanded firmwide. This pattern—evaluation before scale—is becoming a defining trait of successful enterprise agent deployment. Human Resources provides a different perspective on agentic AI. Johnson Controls deployed an AI HR assistant inside Slack to manage policy questions, payroll inquiries, and onboarding support across a global workforce exceeding 100,000 employees. By embedding the agent in a channel employees already use, adoption barriers were reduced significantly. The result was a 30–40% reduction in live HR call volume, allowing HR teams to redirect focus toward strategic workforce initiatives. Similarly, Ciena integrated an AI assistant directly into Microsoft Teams, unifying HR and IT support through a single conversational interface. Employees no longer navigate separate portals; the agent orchestrates requests across backend systems such as Workday and ServiceNow. The technical lesson here is clear: integration breadth drives usability, and usability drives adoption. Engineering and IT operations reveal perhaps the most technically sophisticated application of agentic AI: multi-agent orchestration. In a proof-of-concept developed through collaboration between Microsoft and ServiceNow, an AI-driven incident response system coordinates multiple agents during high-priority outages. Microsoft 365 Copilot transcribes live war-room discussions and extracts action items, while ServiceNow’s Now Assist executes operational updates within IT service management systems. A Semantic Kernel–based manager agent maintains shared context and synchronizes activity across platforms. This eliminates the longstanding gap between real-time discussion and structured documentation, automatically generating incident reports while freeing engineers to focus on remediation rather than clerical tasks. The system demonstrates that orchestration is not conceptual—it is operational. Across these examples, the pattern is consistent. Agentic AI changes knowledge work by absorbing structured cognitive labor: document parsing, compliance classification, research synthesis, workflow routing, transcription, and task coordination. Humans remain essential for judgment, ethics, and accountability, but the operational layer increasingly runs through AI-mediated execution. The result is not incremental productivity improvement; it is structural acceleration of knowledge processes. Design and Governance Challenges – Managing the Risks As agentic AI shifts from answering questions to executing workflows, governance must mature accordingly. These systems retrieve enterprise data, invoke APIs, update records, and coordinate across platforms. That makes them operational actors inside your architecture—not just assistants. The primary shift is this: autonomy increases responsibility. Agents must be observable. Every retrieval, reasoning step, and tool invocation should be traceable. Without structured telemetry and audit trails, enterprises lose visibility into why an agent acted the way it did. Agents must also operate within scoped authority. Least-privilege access, role-based identity, and bounded credentials are essential. An HR agent should not access finance systems. A finance agent should not modify compliance data without policy constraints. Autonomy only works when it is deliberately constrained. Execution boundaries are equally critical. High-risk actions—financial approvals, legal submissions, production changes—should include embedded thresholds or human approval gates. Autonomy should be progressive, not absolute. Cost and performance must be governed just like cloud infrastructure. Agentic systems can trigger recursive calls and model loops. Without usage monitoring, rate limits, and model-tier routing, compute consumption can escalate unpredictably. Finally, agentic systems require continuous evaluation. Real-world testing, live monitoring, and drift detection ensure the system remains aligned with business rules and compliance requirements. These are not “set and forget” deployments. In short, agentic AI becomes sustainable only when autonomy is paired with observability, scoped authority, embedded guardrails, cost control, and structured oversight. Conclusion – Towards the Agentic Enterprise The organizations achieving meaningful returns from agentic AI share a common pattern. They do not treat AI agents as experimental tools. They design them as production systems with defined roles, scoped authority, measurable KPIs, embedded observability, and formal governance layers. When autonomy is paired with integration, memory, orchestration, and governance discipline, agentic AI becomes more than automation—it becomes an operational architecture. Enterprises that master this architecture are not merely reducing costs; they are redefining how knowledge work is executed. In this emerging model, human professionals focus on strategic judgment and innovation, while AI agents manage structured cognitive execution at scale. The competitive advantage will not belong to those who deploy the most AI, but to those who deploy it with architectural rigor and governance maturity. Before we rush to deploy more agents, a few questions are worth asking: If an AI agent executes a workflow in your enterprise today, can you trace every reasoning step and tool invocation behind that decision? Does your architecture treat AI as a conversational layer - or as an operational actor with scoped identity, cost controls, and policy enforcement? Where should autonomy stop in your organization - and who defines that boundary? Agentic AI is not just a capability shift. It is an architectural decision. Curious to hear how others are designing their control planes and orchestration layers.

The Problem We Set Out to Solve Migrating from Oracle PL/SQL to SQL Server T‑SQL is notoriously complex. While SSMA’s rule engine covers hundreds of conversion rules, edge cases, custom logic, and nuanced syntax but it often slips through. Developers end up spending hours manually fixing scripts, validating correctness, and worrying about regressions. The Copilot was built to tackle this pain point: augment SSMA’s rule engine with large language models (LLMs) that can reason about tricky conversions, explain their logic, and accelerate the migration process. But building trust in AI‑generated code meant we had to design an architecture that was controllable, reliable, and secure. SSMA Code Conversion Copilot was released back in the month of May and some of the use cases are elaborated here. This blog talks about the inner working of Copilot. ⚙️ Semantic Kernel for Skill / Plugin Management At the heart of SSMA Copilot lies Semantic Kernel, Microsoft’s open‑source framework for integrating LLMs. It offers two big capabilities: Prompt management — defining prompts as reusable “skills” with parameters like model, temperature, and token count. Agentic orchestration — automating workflows by chaining tools and prompts together. For Copilot, we deliberately chose only prompt management at this point. We have also added native skills such as checking the correctness of syntax and semantics but have not used agentic orchestration for the current implementation. ❌ Why Not Agentic Features? Agentic orchestration can be powerful, but in practice it wasn’t reliable enough for production migrations. Tool selection logic sometimes failed, leading to incorrect validations or spurious edits. Moreover, we saw an issue with latency. Instead, we implemented a deterministic workflow that gave us full control. ✅ Manual Orchestration Workflow Our workflow looks like this (please refer to the diagram): Partial Migration: SSMA generates a baseline conversion. Copilot Authentication: The Copilot is authenticated using the inputs provided by the user. This is where the model is also decided. Alternately, the user can use the managed endpoint that is controlled by Microsoft. LLM Completion: Copilot fills in gaps. Moreover, it explains the solution, points out the error that it is trying to resolve in simple language. Parsing & Compilation: A target‑dialect parser checks syntax. This catches unsupported constructs or binding issues far more reliably than prompt tuning. Spurious Edit Detection: LLMs are instructed to only enhance flagged portions of code. Any edits to “correct” blocks incur penalties, with a strict threshold of zero spurious edits allowed. Query Execution & Data Generation: Where possible, we generate minimal synthetic data (two rows per table) to validate equivalence between source and target queries. Semantic Equivalence Checks: For cases where execution isn’t feasible, we use LLM‑based scoring to judge logical fidelity. This loop repeats until syntactic and semantic correctness is achieved. By using this workflow, we avoided regression spirals and ensured predictable outcomes across dialects. This workflow was tested using our built-in evaluation framework which has leveraged the rich test cases of SSMA. 🔑 Feature Comparison Managed Endpoint Authentication was released with SSMA 10.4 in November 2025. Managed Endpoint BYOK Provisioning OpenAI Endpoint No Yes LLM Model Selection Automatic Manual Authentication Mandatory Entra ID OpenAI Endpoint and Key Private Endpoint Support No Yes Cross Tenant Dependency* Yes No Pricing Free Consumption in actuals *Cross Tenant Dependency: The endpoint is hosted in Microsoft tenant while the authentication happens in the user tenant. 🔒 Privacy and Data Handling A critical point: we don’t store your data. The scripts you provide are used only for generating the migration output. Once the process completes, the data is flushed. No proprietary code or schema information is retained. This design ensures: Security: We run OpenAI in Microsoft tenant following all security protocols. Trust: Copilot is a tool, not a repository. Compliance: Aligns with enterprise privacy expectations. 🌟 Why This Matters By combining Semantic Kernel framework, SSMA Copilot delivers reliable migrations without sacrificing flexibility. And with the managed endpoint, it’s now easier and safer than ever to adopt — no keys, no storage, no friction. This isn’t just about faster migrations. It’s about building trust in AI‑assisted workflows, ensuring correctness, and giving enterprises confidence that their data is secure. Get started with your Copilot based migration journey using SSMA for OracleStaying in the flow: SleekFlow and Azure turn customer conversations into conversions
A customer adds three items to their cart but never checks out. Another asks about shipping, gets stuck waiting eight minutes, only to drop the call. A lead responds to an offer but is never followed up with in time. Each of these moments represents lost revenue, and they happen to businesses every day. SleekFlow was founded in 2019 to help companies turn those almost-lost-customer moments into connection, retention, and growth. Today we serve more than 2,000 mid-market and enterprise organizations across industries including retail and e-commerce, financial services, healthcare, travel and hospitality, telecommunications, real estate, and professional services. In total, those customers rely on SleekFlow to orchestrate more than 600,000 daily customer interactions across WhatsApp, Instagram, web chat, email, and more. Our name reflects what makes us different. Sleek is about unified, polished experiences—consolidating conversations into one intelligent, enterprise-ready platform. Flow is about orchestration—AI and human agents working together to move each conversation forward, from first inquiry to purchase to renewal. The drive for enterprise-ready agentic AI Enterprises today expect always-on, intelligent conversations—but delivering that at scale proved daunting. When we set out to build AgentFlow, our agentic AI platform, we quickly ran into familiar roadblocks: downtime that disrupted peak-hour interactions, vector search delays that hurt accuracy, and costs that ballooned under multi-tenant workloads. Development slowed from limited compatibility with other technologies, while customer onboarding stalled without clear compliance assurances. To move past these barriers, we needed a foundation that could deliver the performance, trust, and global scale enterprises demand. The platform behind the flow: How Azure powers AgentFlow We chose Azure because building AgentFlow required more than raw compute power. Chatbots built on a single-agent model often stall out. They struggle to retrieve the right context, they miss critical handoffs, and they return answers too slowly to keep a customer engaged. To fix that, we needed an ecosystem capable of supporting a team of specialized AI agents working together at enterprise scale. Azure Cosmos DB provides the backbone for memory and context, managing short-term interactions, long-term histories, and vector embeddings in containers that respond in 15–20 milliseconds. Powered by Azure AI Foundry, our agents use Azure OpenAI models within Azure AI Foundry to understand and generate responses natively in multiple languages. Whether in English, Chinese, or Portuguese, the responses feel natural and aligned with the brand. Semantic Kernel acts as the conductor, orchestrating multiple agents, each of which retrieves the necessary knowledge and context, including chat histories, transactional data, and vector embeddings, directly from Azure Cosmos DB. For example, one agent could be retrieving pricing data, another summarizing it, and a third preparing it for a human handoff. The result is not just responsiveness but accuracy. A telecom provider can resolve a billing question while surfacing an upsell opportunity in the same dialogue. A financial advisor can walk into a call with a complete dossier prepared in seconds rather than hours. A retailer can save a purchase by offering an in-stock substitute before the shopper abandons the cart. Each of these conversations is different, yet the foundation is consistent on AgentFlow. Fast, fluent, and focused: Azure keeps conversations moving Speed is the heartbeat of a good conversation. A delayed answer feels like a dropped call, and an irrelevant one breaks trust. For AgentFlow to keep customers engaged, every operation behind the scenes has to happen in milliseconds. A single interaction can involve dozens of steps. One agent pulls product information from embeddings, another checks it against structured policy data, and a third generates a concise, brand-aligned response. If any of these steps lag, the dialogue falters. On Azure, they don’t. Azure Cosmos DB manages conversational memory and agent state across dedicated containers for short-term exchanges, long-term history, and vector search. Sharded DiskANN indexing powers semantic lookups that resolve in the 15–20 millisecond range—fast enough that the customer never feels a pause. Microsoft Phi’s model Phi-4 as well as Azure OpenAI in Foundry Models like o3-mini and o4-mini, provide the reasoning, and Azure Container Apps scale elastically, so performance holds steady during event-driven bursts, such as campaign broadcasts that can push the platform from a few to thousands of conversations per minute, and during daily peak-hour surges. To support that level of responsiveness, we run Azure Container Apps on the Pay-As-You-Go consumption plan, using KEDA-based autoscaling to expand from five idle containers to more than 160 within seconds. Meanwhile, Microsoft Orleans coordinates lightweight in-memory clustering to keep conversations sleek and flowing. The results are tangible. Retrieval-augmented generation recall improved from 50 to 70 percent. Execution speed is about 50 percent faster. For SleekFlow’s customers, that means carts are recovered before they’re abandoned, leads are qualified in real time, and support inquiries move forward instead of stalling out. With Azure handling the complexity under the hood, conversations flow naturally on the surface—and that’s what keeps customers engaged. Secure enough for enterprises, human enough for customers AgentFlow was built with security-by-design as a first principle, giving businesses confidence that every interaction is private, compliant, and reliable. On Azure, every AI agent operates inside guardrails enterprises can depend on. Azure Cosmos DB enforces strict per-tenant isolation through logical partitioning, encryption, and role-based access control, ensuring chat histories, knowledge bases, and embeddings remain auditable and contained. Models deployed through Azure AI Foundry, including Azure OpenAI and Microsoft Phi, process data entirely within SleekFlow’s Azure environment and guarantees it is never used to train public models, with activity logged for transparency. And Azure’s certifications—including ISO 27001, SOC 2, and GDPR—are backed by continuous monitoring and regional data residency options, proving compliance at a global scale. But trust is more than a checklist of certifications. AgentFlow brings human-like fluency and empathy to every interaction, powered by Azure OpenAI running with high token-per-second throughput so responses feel natural in real time. Quality control isn’t left to chance. Human override workflows are orchestrated through Azure Container Apps and Azure App Service, ensuring AI agents can carry conversations confidently until they’re ready for human agents. Enterprises gain the confidence to let AI handle revenue-critical moments, knowing Azure provides the foundation and SleekFlow provides the human-centered design. Shaping the next era of conversational AI on Azure The benefits of Azure show up not only in customer conversations but also in the way our own teams work. Faster processing speeds and high token-per-second throughput reduce latency, so we spend less time debugging and more time building. Stable infrastructure minimizes downtime and troubleshooting, lowering operational costs. That same reliability and scalability have transformed the way we engineer AgentFlow. AgentFlow started as part of our monolithic system. Shipping new features used to take about a month of development and another week of heavy testing to make sure everything held together. After moving AgentFlow to a microservices architecture on Azure Container Apps, we can now deploy updates almost daily with no down time or customer impact. And this is all thanks to native support for rolling updates and blue-green deployments. This agility is what excites us most about what's ahead. With Azure as our foundation, SleekFlow is not simply keeping pace with the evolution of conversational AI—we are shaping what comes next. Every interaction we refine, every second we save, and every workflow we streamline brings us closer to our mission: keeping conversations sleek, flowing, and valuable for enterprises everywhere.Azure Skilling at Microsoft Ignite 2025
