Moonshot AI claims Kimi K3 is second only to OpenAI's GPT-5.6 Sol and Anthropic's Claude Fable 5 in performance, priced at $15 per million output tokens, compared to about $30 for GPT-5.6 Sol and $50 for Fable 5. Alibaba's Qwen3.8 claims to be 'second only to Fable 5'. Both companies plan to open-source their models, allowing developers to download, use, and modify them, in stark contrast to the closed proprietary approaches of leading US AI labs like OpenAI, Anthropic, and Google.
Notably, token prices are not directly comparable; more expensive models may generate better responses with fewer tokens, and companies often subsidize inference costs to attract customers. Thus, cheaper does not automatically mean better or lower overall cost. But with the performance gap narrowing, Chinese models have a clear price advantage, which has already prompted some US startups to switch to cheaper Chinese models.
