Microsoft has expanded Foundry Agent Service with a wide range of AI models. LLMs from Anthropic, DeepSeek AI, Meta, Microsoft, and xAI are now available.
The expanded catalog allows developers to choose the right model for their specific application. The different LLMs excel in a variety of ways, from coding to reasoning based on long inputs. Examples include DeepSeek-R1 (version 0528) and -V3 (0324), as well as variants of Grok-4.
This brings Microsoft’s AI service a step closer to the model selection of Vertex AI Agent Service, Google’s counterpart to Microsoft’s offering. Apart from Google’s own models, which are exclusive to Google Cloud, Google offers mostly the same LLMs. The big absentee is OpenAI, which is only available from Microsoft when it comes to closed-source models. These include the latest variants (GPT-5.1) and legacy options such as o4-mini, o3, GPT-4.1, o1 and (for now) GPT-4o and GPT-4.
