Decrypt is proud to see Kimi-k2.5 provide the foundation., Kimi.ai March 20, 2026.
Key facts
- The latest version, K2.6, released in April 2026, now scores 58.6% on SWE-Bench Pro—a benchmark measuring real-world software engineering on actual GitHub issues—putting it ahead of GPT-5.4 at 57.7%
- Moonshot says K2.6 supports up to 300 parallel sub-agents executing across 4,000 coordinated steps simultaneously—the architecture WebBridge taps into when handling complex, multi-step browser tasks
- For example, you could ask your agent to browse Amazon for mechanical keyboards under $150 with at least 4.5 stars and return a ranked comparison, and it would understand your instruction and search
- The announcement lasted less than 24 hours before a developer named Fynn intercepted API traffic and found a model identifier: kimi-k2p5-rl-0317-s515-fast
Summary
Kimi WebBridge runs entirely on your machine using Chrome DevTools Protocol, so your login sessions and page content never touch Moonshot's servers. The model driving it, Kimi K2.6, currently ranks first on the SWE-Bench Pro benchmark with a 58.6% score, ahead of GPT-5.4 and Claude Opus 4.6. Beijing-based Moonshot AI has released Kimi WebBridge, a browser extension that lets AI agents interact with websites the way a person would—searching, clicking, typing, scrolling, and extracting data—all while running locally on your device. Right now most AI browser automation pipes your data through cloud infrastructure, which means your logged-in sessions and private page content go with it. But Kimi WebBridge does something different.
