About
MAI-1 Preview is Microsoft AI’s first end-to-end trained foundation model, built entirely in-house as a mixture-of-experts architecture. Pre-trained and post-trained on approximately 15,000 NVIDIA H100 GPUs, it is designed to follow instructions and generate helpful, responsive text for everyday user queries, representing a prototype of future Copilot capabilities. Now available for public testing on LMArena, MAI-1 Preview delivers an early glimpse into the platform’s trajectory, with plans to roll out select text-based applications within Copilot over the coming weeks to gather user feedback and refine performance. Microsoft reinforces that it will continue combining its own models, partner models, and developments from the open-source community to flexibly power experiences across millions of unique interactions each day.

About
Trajectory is the platform for continual learning, built to turn real product usage into AI that continuously improves. It helps every product become a living system by treating every edit, retry, correction, re-prompt, and user acceptance as a signal. User behavior reflects real task success more accurately than any benchmark, and Trajectory gives teams a creative surface to observe, direct, and craft the intelligence behind their product. With a lightweight SDK, teams can plug Trajectory into an AI product and start capturing the signals users are already generating, including traces, corrections, re-prompts, and edits. It helps teams understand what the model is learning, steer it toward what matters, and deploy updates with confidence. It is designed for domains where model behavior shifts meaningfully from one setting to the next, making steerability a core operational requirement rather than just a research interest.
