Microsoft AI announced a new large language model, MAI-Base-2, claiming it outperforms the OpenAI model behind GPT 5.6 Sol while using far less compute. The model is not fully open, but will be licensed to select partners.
Microsoft on October 12 unveiled Azure Maia 300, its third-generation in-house AI accelerator. The inference-focused chip promises 40% more tokens per megawatt than leading GPU systems, with production deployments starting in 2027.
On October 9, Microsoft released Decision-1, a scoring model for structured decisions. It writes no text — it picks the best option from a given set and returns probability scores. Built on Alibaba's Qwen3.5-9B, input costs $0.042 per million tokens, output is free. The decision-model track that startups heated up last month now has Microsoft, OpenAI, and Cloudflare all in.
Microsoft will hold an event in San Francisco at 1 AM Beijing time on October 8, with CEO Satya Nadella and NVIDIA CEO Jensen Huang sharing the stage to unveil the Surface Laptop Ultra powered by the RTX Spark chip — up to 128GB of unified memory, capable of running 120B-parameter models locally. Microsoft wants to move AI agents from the cloud back onto local devices.
