Microsoft launches its first in-house reasoning model, MAI-Thinking-1, now on Foundry

微软首发自研推理模型MAI-Thinking-1

Microsoft CEO Mustafa Suleyman announced the first in-house reasoning model, MAI-Thinking-1, now available on Microsoft Foundry. The model was built from scratch. The post does not disclose parameter count, benchmarks, pricing, or technical details.

Why it matters: Microsoft's first in-house reasoning model, announced by Mustafa Suleyman — strong topic signal. But zero benchmarks, params, or pricing disclosed, so information density is too low to score higher. Parked at the featured threshold; will adjust once real numbers surface.
