Microsoft Begins Rolling Out Its Own Frontier Foundation Models

Microsoft's Foundry platform has grown to more than 11,000 models from OpenAI, Anthropic, Meta, Mistral, DeepSeek, and others, plus its own Cognitive Services and Phi models. Microsoft has now started rolling out its own large-scale frontier foundation models, filling the gap in its catalog. The move follows Microsoft Research's years of benchmark-leading work, though its past focus was on more specialized models rather than general-purpose ones.

Why it matters: Teams building on Foundry will soon have a first-party frontier model option, which could change model selection, cost, and vendor-dependence decisions for AI applications.
