According to CoinMeta, a foreign AI blogger da7em has put forward a rather controversial view: since Anthropic began to strictly prevent other companies from distilling Claude, Chinese large models seem to have collectively fallen silent. He listed the performances of four manufacturers: Kimi's K3 took about 100 days to release before K3.1 Pro was released, but the new model did not achieve any major breakthroughs. DeepSeek has been slow to launch a flagship model that satisfies him, and the interval between the releases of Zhispu's flagship models has exceeded three months. Alibaba's feedback on the preview version of Qwen4-Max was mostly disappointing. He believes that the performance of these manufacturers is attributed to Anthropic having strengthened anti-distillation measures.
