[AINews] 微软Build大会：MAI-Thinking-1与MAI系列模型
英文摘要
Microsoft at Build 2026 announced seven new MAI models, including the flagship MAI-Thinking-1 reasoning model with 35B active parameters, 256K context, and strong benchmark scores like 97% on AIME 2025. The company released a highly transparent 109-page technical report that impressed researchers, emphasizing clean data lineage and no use of synthetic data or distillation. Build also focused on local AI with Windows as an agent runtime, the RTX Spark Dev Box, and Project Solara/Scout agent hardware. The GitHub Copilot app was unveiled as a desktop home for agent-native development, and Web IQ was introduced as a new grounding API for agents. Overall, the event positioned Microsoft as both a first-party frontier model developer and a multi-tier AI platform company.
中文摘要
微软在Build 2026上发布了七款新的MAI模型，包括旗舰推理模型MAI-Thinking-1，具有35B活跃参数、256K上下文窗口以及AIME 2025 97%等强大基准测试成绩。公司发布了一份长达109页的高度透明技术报告，强调数据来源清晰、未使用合成数据或蒸馏技术，获得了研究界好评。Build还聚焦本地AI，将Windows打造为代理运行时，推出RTX Spark Dev Box和Project Solara/Scout代理硬件。GitHub Copilot应用作为代理原生开发的桌面中心亮相，Web IQ作为代理新型接地API推出。整体上，活动将微软定位为既是第一方前沿模型开发者，又是多层次AI平台公司。
