Moonshot的Kimi K3在前端代码上超越Fable 5，但在复杂数学上大幅落后

Moonshot's AI model Kimi K3 is getting a lot of attention in the Western AI community. The big question is how close it actually gets to the best Western models. Two new data points paint a mixed picture. In the Code Arena: Frontend benchmark, which ranks models based on human preference ratings , Kimi K3 scores 1,679, beating Claude Fable 5 (1,631), GPT-5.6 Sol (1,618), and every other tested model by a wide margin. It's the first time a Chinese model has claimed the top spot on this benchmark. The picture looks different for hard math. According to data from Epoch AI , Kimi K3 hits only about 39 percent accuracy on FrontierMath Tier 4, the benchmark's hardest expert-level math tasks. Models from OpenAI and Anthropic score close to 90 percent there in some cases.
