Microsoft is reportedly evaluating Moonshot AI’s Kimi K3 model for integration into its Copilot service on Azure, a move that would push two of the biggest names in AI, OpenAI and Anthropic, at least partially to the sidelines on one of the world’s largest cloud platforms.
The timing is notable. Kimi K3 was only released on July 16, 2026, and it already has people paying attention for the right reasons.
What Kimi K3 actually is
Kimi K3 is a multimodal model built by Beijing-based Moonshot AI, packing 2.8 trillion parameters and a context window of one million tokens.
The model scored 1,679 points on LMArena’s Frontend Code Arena, landing in first place and beating out the current field of competitors.
