微软首款高级推理AI模型MAI-Thinking-1发布
Microsoft’s first advanced reasoning AI is here
微软在Build 2026上发布了其首款高级推理AI模型MAI-Thinking-1。该模型被定位为“中等规模”，能在“关键”软件工程基准测试中达到领先模型的水平。微软称其完全从头使用干净数据进行训练，未涉及从第三方模型进行知识蒸馏。这标志着微软在自研AI模型上迈出重要一步，此前其主要依赖OpenAI。近期两家公司已重新协商合作协议，关系有所松绑。
微软自己从头训练的推理模型，不用任何第三方蒸馏数据，这可能是微软系 Agent 和 Copilot 底座更换的信号，值得盯着看。
MAI-Thinking-1 is one of seven new models announced at Build 2026.
Microsoft announced a bunch of new in-house AI models at Build 2026, including a new “flagship” model: MAI-Thinking-1. It’s an ambitious step into model development for Microsoft, which introduced its initial in-house models last year — before then, it had relied on OpenAI’s models. The two companies recently renegotiated their deal to loosen ties.
According to Microsoft, MAI-Thinking-1 is a “medium-sized model” that “matches leading models” on “key” software engineering benchmarks. Microsoft says the company “trained it from the ground up on clean data, without distillation from third-party models.”
As for other models announced today, they’re focused on image generation, transcription, voice, and coding.
MAI-Image 2.5 and the flash version can do text-to-image and image editing. MAI-Transcribe-1.5 is “five times faster than competing models.” MAI-Voice-2 and the flash version of that model (which Microsoft says is “coming soon”) add 15 new languages and new options for voices. The new coding model, MAI-Code-1-Flash, is “inference-efficient” and is integrated into GitHub Copilot and Visual Studio Code.
