An open-weights Chinese model beat Claude, GPT-5.5, and Gemini in a coding contest
If you build with Claude or Claude Code, this is the kind of result that forces a reset. The interesting part isn’t just that an open-weights Chinese model won a programming challenge — it’s that the winner came from a messy, real-time, server-connected task where code quality, strategy, and failure modes all mattered. In Rohana Rezel’s ongoing AI Coding Contest, Day 12 used the Word Gem Puzzle: a sliding-tile word game with a TCP server, a 10-second limit per round, and objective scoring. Kimi
