🌙 China’s Moonshot: Kimi K2 Thinking Challenges GPT-5 and Claude 4.5

NewBits Digest feature image for article on Kimi K2 Thinking, highlighting Moonshot AI’s reasoning model and benchmark gains.

🤖 What’s New — Kimi K2 Thinking


Alibaba-backed Moonshot AI has unveiled Kimi K2 Thinking, a reasoning model that reportedly matches or surpasses top systems like GPT-5 and Claude 4.5 Sonnet—at a fraction of the cost.


📊 The Details


  • Kimi K2 Thinking is said to outperform GPT-5 and Claude 4.5 on multiple agentic reasoning benchmarks.


  • Achieved a reported 44.9% on Humanity’s Last Exam 🧩.


  • Shows major progress in coding vs. its predecessor from four months ago.


  • Can autonomously chain 200–300 tool calls and exhibits advanced creative writing skills.


  • Reported training cost: under $5 million, far below typical frontier model budgets.


⚙️ Why Kimi K2 Thinking Matters


NVIDIA’s Jensen Huang said days ago that China is only “nanoseconds behind” in AI—and Kimi K2 Thinking is being held up as evidence. With near-frontier capability, an emphasis on efficiency, and aggressive benchmark gains, Moonshot AI is positioning China as a serious contender in the global AI race.


🌍 The Bigger Picture


If the reported results hold up under independent evaluation, Kimi K2 Thinking could pressure Western labs on price-performance and accelerate the pace of open evaluation standards across reasoning and agentic workflows.
