A Beijing-based AI startup just walked into Silicon Valley’s living room, rearranged the furniture, and argued the place looks better this way.

What Moonshot actually built Kimi K3 is multimodal out of the box, with native vision support baked into the architecture rather than bolted on as an afterthought. The model has topped certain specialized benchmarks, including the Arena.ai Frontend Code Arena for coding and agentic tasks.
