Kimi K3 编码代理评测

Kimi K3 in Kimi Code CLI scores 57 and ranks #5 on the Artificial Analysis Coding Agent Index. Its performance is just behind Grok 4.5, in line with GPT-5.6 Terra and GPT-5.5, and ahead of Opus 4.8 Key results: ➤ Joint #5 overall on the Artificial Analysis Coding Agent Index: Kimi K3 scores 57, matching GPT-5.6 Terra max (57) and GPT-5.5 xhigh (57). It outperforms Opus 4.8 max (55), sits just behind Grok 4.5 high (58) and Fable 5 max (59), and trails GPT-5.6 Sol max (61). ➤ Strong performance across all three coding evaluations: K3 scores 84% on Terminal-Bench v2, 64% on DeepSWE, and 23% on SWE-Atlas-QnA. It outperforms Fable 5 on Terminal-Bench, Grok 4.5 and Opus 4.8 on DeepSWE, and GPT-5.6 Terra and GPT-5.5 on SWE-Atlas-QnA. ➤ Cost-efficient frontier coding performance: K3 costs an average of $3.18 per task. It is 55% cheaper than GPT-5.6 Sol max ($7.08), 73% cheaper than Fable 5 max ($11.72), 37% cheaper than GPT-5.5 xhigh ($5.07), and 59% cheaper than Opus 4.8 max ($7.70). Grok 4.5 high ($2.59) and GPT-5.6 Terra max ($2.76) are slightly cheaper. ➤ Leads open weight coding models (assuming weights are released): K3’s score of 57 is substantially ahead of other tested open-weight configurations, including GLM-5.2 at 40 and DeepSeek V4 Pro at 29.
