It represents Microsoft's in-house reasoning model capability, distinct from their Azure-hosted OpenAI models. ## At a Glance **Where MAI Thinking 1 leads** - 85% MMLU-Pro — strong academic knowledge with reasoning - 73.5% SWE-Bench Verified — competitive software engineering - 72.0% BFCL v3 — good function calling with reasoning - Microsoft-built: not an OpenAI model resold **Where it lags** - Proprietary: no open weights - February 2025 knowledge cutoff — older than competing models - Limited public benchmark data - Text-only **Best for:** Azure-native deployments requiring Microsoft-built reasoning models; teams needing MAI capabilities in Azure AI Foundry. ## What MAI Thinking 1 Is MAI Thinking 1 (released May 2025) is Microsoft's first publicly released in-house reasoning model — distinct from the GPT models that Microsoft distributes via Azure OpenAI. "MAI" stands for Microsoft AI, and the "Thinking" designation indicates a chain-of-thought reasoning architecture. The model is positioned as Microsoft's answer to OpenAI's o-series for teams that prefer Microsoft-built models over OpenAI-built ones in Azure. With 85% MMLU-Pro and 73.5% SWE-Bench, it is competitive with models at a similar capability tier from the same period. ## Specifications | Field | Value | |---|---| | Organization | Microsoft | | License | Proprietary (API only) | | Release date | May 2025 | | Knowledge cutoff | February 2025 | | Modality | Text only | | Architecture | Chain-of-thought reasoning | ## Pricing Available via Microsoft Azure AI Foundry.
