In the latest Code Arena full-stack Web development leaderboard, Moonshot's Kimi K3 (Max) took 1st place with a score of 1664, beating OpenAI's GPT-5.6 and Anthropic's Claude Fable 5.
Developer @casperhansen noted after testing that Kimi K3's internal reasoning is quite pleasant to read, and the model feels very sharp overall. He believes that for ML frontier work, Kimi K3 performs closely to, or even better than, Claude Fable because it doesn't get "nerfed" like Opus.
