Chinese startup Moonshot AI's new model, Kimi K2 Thinking, has claimed superior performance over both OpenAI's GPT-5 and Anthropic's Claude Sonnet 4.5 in key reasoning and agentic benchmarks. The open-source model achieved 60.2% on the BrowseComp agentic search test and 44.9% on Humanity’s Last Exam, signaling a major breakthrough for Chinese foundational models. This open-weight release intensifies the global AI capabilities race, shifting the focus beyond US-based closed models. The new benchmark for agentic reasoning capacity is now set outside of Silicon Valley.
