Kimi K3.1 Pro 编码基准超过 GPT-6 Astra
Moonshot 发布 Kimi K3.1 Pro，Terminal-Bench 4.0 得 65.7%，高于 GPT-6 Astra 的 58.2%，价格约为其七分之一。
A $50 billion Chinese AI startup just released a model that beats GPT-6 Astra on coding benchmarks. Most Americans have never heard its name. Moonshot AI released Kimi K3.1 Pro today October 24, 2026. It scored 65.7% on Terminal-Bench 4.0, the benchmark that tests coding agents on real-world tasks. GPT-6 Astra scored 58.2%. Claude Opus 5.5 scored 66.4%. Kimi K3.1 Pro sits between the two most powerful AI models on earth and costs a fraction of both. $2 per million input tokens. $10 per million output tokens. Claude Opus 5.5 charges $15/$75. GPT-6 Astra charges more. Kimi is 7-8x cheaper on input and 7.5x cheaper on output. The model is built on Kimi K3 the largest open-weight model ever released at 2.8 trillion parameters. Full model weights for K3.1 Pro will be open-sourced by November 4. Bloomberg called it “Moonshot’s first major upgrade since its own DeepSeek moment.” And most people in the West have never typed “http://kimi.ai” into a browser.
