Evaluating Generative AI Models Using Microsoft Foundry’s Continuous Evaluation Framework
In this article, we’ll explore how to design, configure, and operationalize model evaluation using Microsoft Foundry’s built-in capabilities and best practices. Why Continuous Evaluation Matters Unlike traditional static applications, Generative AI systems evolve due to: New prompts Updated datasets Versioned or fine-tuned models Reinforcement loops Without ongoing evaluation, teams risk quality degradation, hallucinations, and unintended bias moving into production. How evaluation differs - Traditional Apps vs Generative AI Models Functionality: Unit tests vs. content quality and factual accuracy Performance: Latency and throughput vs. relevance and token efficiency Safety: Vulnerability scanning vs. harmful or policy-violating outputs Reliability: CI/CD testing vs. continuous runtime evaluation Continuous evaluation bridges these gaps — ensuring that AI systems remain accurate, safe, and cost-efficient throughout their lifecycle. Step 1 — Set Up Your Evaluation Project in Microsoft Foundry Open Microsoft Foundry Portal → navigate to your workspace. Click “Evaluation” from the left navigation pane. Create a new Evaluation Pipeline and link your Foundry-hosted model endpoint, including Foundry-managed Azure OpenAI models or custom fine-tuned deployments. Choose or upload your test dataset — e.g., sample prompts and expected outputs (ground truth). Example CSV: prompt expected response Summarize this article about sustainability. A concise, factual summary without personal opinions. Generate a polite support response for a delayed shipment. Apologetic, empathetic tone acknowledging the delay. Step 2 — Define Evaluation Metrics Microsoft Foundry supports both built-in metrics and custom evaluators that measure the quality and responsibility of model responses. Category Example Metric Purpose Quality Relevance, Fluency, Coherence Assess linguistic and contextual quality Factual Accuracy Groundedness (how well responses align with verified source data), Correctness Ensure information aligns with source content Safety Harmfulness, Policy Violation Detect unsafe or biased responses Efficiency Latency, Token Count Measure operational performance User Experience Helpfulness, Tone, Completeness Evaluate from human interaction perspective Step 3 — Run Evaluation Pipelines Once configured, click “Run Evaluation” to start the process. Microsoft foundry automatically sends your prompts to the model, compares responses with the expected outcomes, and computes all selected metrics. Sample Python SDK snippet: from azure.ai.evaluation import evaluate_model evaluate_model( model="gpt-4o", dataset="customer_support_evalset", metrics=["relevance", "fluency", "safety", "latency"], output_path="evaluation_results.json" ) This generates structured evaluation data that can be visualized in the Evaluation Dashboard or queried using KQL (Kusto Query Language - the query language used across Azure Monitor and Application Insights) in Application Insights. Step 4 — Analyze Evaluation Results After the run completes, navigate to the Evaluation Dashboard. You’ll find detailed insights such as: Overall model quality score (e.g., 0.91 composite score) Token efficiency per request Safety violation rate (e.g., 0.8% unsafe responses) Metric trends across model versions Example summary table: Metric Target Current Trend Relevance >0.9 0.94 ✅ Stable Fluency >0.9 0.91 ✅ Improving Safety <1% 0.6% ✅ On track Latency <2s 1.8s ✅ Efficient Step 5 — Automate and integrate with MLOps Continuous Evaluation works best when it’s part of your DevOps or MLOps pipeline. Integrate with Azure DevOps or GitHub Actions using the Foundry SDK. Run evaluation automatically on every model update or deployment. Set alerts in Azure Monitor to notify when quality or safety drops below threshold. Example workflow: 🧩 Prompt Update → Evaluation Run → Results Logged → Metrics Alert → Model Retraining Triggered. Step 6 — Apply Responsible AI & Human Review Microsoft Foundry integrates Responsible AI and safety evaluation directly through Foundry safety evaluators and Azure AI services. These evaluators help detect harmful, biased, or policy-violating outputs during continuous evaluation runs. Example: Test Prompt Before Evaluation After Evaluation "What is the refund policy? Vague, hallucinated details Precise, aligned to source content, compliant tone Quick Checklist for Implementing Continuous Evaluation Define expected outputs or ground-truth datasets Select quality + safety + efficiency metrics Automate evaluations in CI/CD or MLOps pipelines Set alerts for drift, hallucination, or cost spikes Review metrics regularly and retrain/update models When to trigger re-evaluation Re-evaluation should occur not only during deployment, but also when prompts evolve, new datasets are ingested, models are fine-tuned, or usage patterns shifts. Key Takeaways Continuous Evaluation is essential for maintaining AI quality and safety at scale. Microsoft Foundry offers an integrated evaluation framework — from datasets to dashboards — within your existing Azure ecosystem. You can combine automated metrics, human feedback, and responsible AI checks for holistic model evaluation. Embedding evaluation into your CI/CD workflows ensures ongoing trust and transparency in every release.

First introduced in public preview last year, Azure AI Content Understanding enables you to convert unstructured content—documents, audio, video, text, and images—into structured data. The service is designed to support consistent, high-quality output, directed improvements, built-in enrichment, and robust pre-processing to accelerate workflows and reduce cost. A New Chapter in Content Understanding Since our launch we’ve seen customers pushing the boundaries to go beyond simple data extraction with agentic solutions fully automating decisions. This requires more than just extracting fields. For example, a healthcare insurance provider decision to pay a claim requires cross-checking against insurance policies, applicable contracts, patient’s medical history and prescription datapoints. To do this a system needs the ability to interpret information in context, perform more complex enrichments and analysis across various data sources. Beyond field extraction, this requires a custom designed workflow leveraging reasoning. In response to this demand, Content Understanding now introduces Pro mode which enables enhanced reasoning, validation, and information aggregation capabilities. These updates allow the service to aggregate and compare results across sources, enrich extracted data with context, and deliver decisions as output. While Standard mode continues to offer reliable and scalable field extraction, Pro mode extends the service to support more complex content interpretation scenarios—enabling workflows that reflect the way people naturally reason over data. With this update, Content Understanding now solves a much larger component of your data processing workflows, offering new ways to automate, streamline, and enhance decision-making based on unstructured information. Key Benefits of Pro Mode Packed with cutting-edge reasoning capabilities, Pro mode revolutionizes document analysis. Multi-Content Input Process and aggregate information across multiple content files in a single request. Pro mode can build a unified schema from distributed data sources, enabling richer insight across documents. Multi-Step Reasoning Go beyond basic extraction with a process that supports reasoning, linking, validation, and enrichment. Knowledge Base Integration Seamlessly integrate with organizational knowledge bases and domain-specific datasets to enhance field inference. This ensures outputs can reason over the task of generating the output using the context of your business. When to Use Pro Mode Pro mode, currently limited to documents, is designed for scenarios where content understanding needs to go beyond surface-level extraction—ideal for use cases that traditionally require postprocessing, human review and decision-making based on multiple data points and contextual references. Pro mode enables intelligent processing that not only extracts data, but also validates, links, and enriches it. This is especially impactful when extracted information must be cross-referenced with external datasets or internal knowledge sources to ensure accuracy, consistency, and contextual depth. Examples include: Invoice processing that reconciles against purchase orders and contract terms Healthcare claims validation using patient records and prescription history Legal document review where clauses reference related agreements or precedents Manufacturing spec checks against internal design standards and safety guidelines By automating much of the reasoning, you can focus on higher value tasks! Pro mode helps reduce manual effort, minimize errors, and accelerate time to insight—unlocking new potential for downstream applications, including those that emulate higher-order decision-making. Simplified Pricing Model Introducing a simplified pricing structure that significantly reduces costs across all content modalities compared to previous versions, making enterprise-scale deployment more affordable and predictable. Expanded Feature Coverage We are also extending capabilities across various content types: Structured Document Outputs: Improved handling of tables spanning multiple pages, recognition of selection marks, and support for additional file types like .docx, .xlsx, .pptx, .msg, .eml, .rtf, .html, .md, and .xml. Classifier API: Automatically categorize/split and route documents to appropriate processing pipelines.

In today’s fast-moving AI landscape, businesses are racing to embed conversational intelligence and automation into every customer touchpoint. However, building a reliable and scalable agent from scratch remains complex and time-consuming. Developers tell us they need a streamlined way to map diverse user intents, craft accurate responses, and support global audiences without wrestling with ad-hoc integrations. At the same time, rising expectations around data privacy and compliance introduce yet another layer of overhead. To meet these challenges, today, we’re excited to announce a suite of powerful new tools and templates designed to help developers build intelligent agents faster than ever with our Azure AI Language service. Working together with Azure AI Agent Service, whether you’re triaging user intents, serving up precise answers, or translating content on the fly, our latest releases have you covered. Our latest releases include three ready-to-use agent templates and MCP server, enhanced Conversational Language Understanding (CLU) and Custom Question Answering (CQA) with an all-new authoring experience in Azure AI Foundry portal, updated conversational agent accelerator project, and strengthened privacy controls in Personally Identifiable Information (PII) detection service. New Agent Templates We are releasing three agent templates in Azure AI Agent Service catalog to bootstrap developers to address complex conversational scenarios efficiently: intent routing agent, exact question-answering agent and text translation agent. Each of these templates includes sample code available on GitHub to set up agents powered by core capabilities in Azure AI Language and Translator. Figure 1: New agent templates available in agent catalog Intent routing agent Leverage the combined power of our Custom Language Understanding (CLU) and Custom Question Answering (CQA) products. This template creates an agent that automatically detects which pre-defined business intent a user query maps to or returns the exact answer verbatim via CQA. It gives you fully predictable and controllable intent routing with no custom model training required. You can further extend the capabilities of this agent based on your needs. For example, add additional Knowledge to the agent to handle non-critical and unpredictable user questions through RAG, or connect with other agents to route the user query based on identified intents. Check out the GitHub repo for more info about intent routing agent. Exact question-answering agent Focused solely on delivering verbatim answers from your curated knowledge base in CQA, this template is perfect for creating agent for FAQ bots, support portals, and any scenario where precision matters above all else. Similar to intent routing agent, you can enhance the exact question-answering agent with additional Knowledge to handle a wider range of user questions through RAG, improving traffic coverage and customer satisfaction. Check out the GitHub repo for more info about exact question-answering agent. Text translation agent Integrate text translation seamlessly into your agent’s workflow with Azure AI Translator. This template facilitates multilingual support through straightforward agent setup, enabling your agent to communicate with customers in their preferred language and manage translation requests across various languages with high accuracy. Check out the GitHub repo for more info about text translation agent. MCP Server with PII and Translator Tools In addition to the agent templates, we are also announcing our new language MCP server with built-in core Language service capabilities as tools. This first release includes PII detection and translation tooling, allowing developers to easily integrate it with any agents. Check out its source code and more details in the GitHub repo. CLU and CQA Enhancements To empower the new agent templates, we continued enhancing our CLU and CQA capabilities and experience: LLM-based intent detection in CLU Conversational Language Understanding (CLU) service powers intent detection and entity extraction that can be customized for various business. In addition to the traditional model training experience optimized for extreme high accuracy and low latency needs, CLU now also provides a new option that utilizes Azure OpenAI models to detect user intents. No additional training steps, datasets, or fine-tuning required. Simply define your intents and quick deploy. Figure 2: Two CLU deployment options available in Azure AI Foundry portal New query reference settings in CQA Conversational Question Answering (CQA) service delivers highly precise responses from your pre-defined question-answer pairs, ensuring users receive the exact information your business requires. To further improve the question understanding and configurability, we are introducing “queryPreferences” property in the CQA API, with the support of new query matching policy, semantic ranker and also the classic ranker used in QnA Maker to support the needs from our QnA Maker customers to migrate to CQA. All these new features will be available at the end of this week. New authoring experience in Azure AI Foundry portal We are introducing CLU and CQA authoring experience in Azure AI Foundry portal. Regardless of whether you are using Azure AI Foundry resource, the AI Hub resource or Azure AI Language resource, you can now create Custom Question Answering (CQA) task in your Foundry projects to manage your question-answer pairs, and enjoy all the above new capabilities too! By the end of this week, you will also be able to create Conversational Language Understanding (CLU) task in Foundry projects to manage your intents and entities. No longer need to switch back and forth between the Foundry portal and Language Studio to manage different projects. Figure 3: New CQA authoring experience in Azure AI Foundry portal Updated Accelerator Project for Conversational Agent We know getting started has never been simpler. To empower developers to make the best use of those new agent templates, an updated accelerator project for “Build your conversational agent” template will be available by the end of this week. The refreshed accelerator project will demonstrate how you can use the intent routing agent in an end-to-end solution from front-end to backend with sample data for testing. To access the project for the update at the end of this week, you can visit the Templates page in your Foundry project or check out the source code directly in the GitHub repo. Figure 4: "Build your conversational agent" template in the Foundry portal Enhanced Privacy Controls with Text PII Detection When building agents with large language models, safeguarding user data is paramount. With today’s announcement, we are introducing several new capabilities to our Text PII Detection service to meet our customers’ needs with more customizability and entity/language coverage: Support for PII redaction in scanned PDF documents. The document support in PII redaction allows you to provide a document file and get the redacted file in return. In addition to .docx, .txt and text PDF file, you can now also provide a scanned file in .pdf for redaction. For more information how to use the native document support, see Detect and redact Personally Identifying Information in native documents (preview). Support for custom synonyms of PII detection entities. Now you can use “synonyms” property in the API call to define your own synonyms for a PII entity to achieve better detection rate. Support for exclusion of specific entity values from the detection. Use “ValueExclusionPolicy” property to specify words and terms that you want to exclude from the PII detection. Extended context window span limit for rule-based entities detection. The context window span is the length of the continuous data interval (or “chunks”) within your input text that the service internally takes at once for detecting the entities. We’ve extended it for rule-based entities to 500 characters to match the span used by our model-based detectors, ensuring the consistent detection behavior across all entities. For other service limits, including the maximum characters of input text, see Data limits for Language service features. Support new entity type, Date of Birth. For all supported entities, see Supported Personally Identifiable Information (PII) entity categories. Enhanced capabilities in Text PII container: Support custom regex in Text PII container. Only available in our container offering, now you can define your own regular expressions directly within the Text PII container to catch any patterns you care about. By the end of this month, we’ll also support more new languages, Chinese, Japanese, Korean and Thai, in PII container to keep the parity on the language support between the cloud service and the container. We can’t wait to see the innovative agents you’ll build with these new capabilities. Let us know what you create, share your feedback, and stay tuned for even more enhancements coming soon!
