Microsoft Foundry is Microsoft's enterprise AI platform for building, grounding, deploying, evaluating, and governing AI applications and agents. It provides access to a broad selection of foundation, open, reasoning, multimodal, and industry-specific models, with tools for model customization, model routing, agent development, organizational grounding, business-system connections, and hosted deployment. Its lifecycle features include tracing, built-in evaluation for qualities such as relevance and groundedness, runtime security controls, and unified governance across agents, tools, and knowledge sources. In the cited workshop, models hosted on Foundry were accessed through the OpenAI SDK for scenario testing and evaluations.
