๐ ๏ธ Technical Deep Dive
- Kimi WebBridge operates as a Chrome/Edge browser extension paired with a local background service, often referred to as "Kimi Claw."
- Communication between the extension and the local agent process is facilitated via the Chrome DevTools Protocol (CDP).
- The agent performs visual, click-and-scroll interactions, mimicking human behavior rather than relying on direct API calls, allowing it to "see" websites as a user would.
- It is powered by Moonshot AI's Kimi K2.6 model, an open-source native multimodal agentic model.
- Kimi K2.6 is built on a Mixture-of-Experts (MoE) architecture, featuring 1 trillion total parameters with 32 billion active parameters per inference.
- The model supports long-horizon coding capabilities and advanced agentic task orchestration, capable of scaling to 300 parallel sub-agents executing up to 4,000 coordinated steps.
- Kimi K2.6 accepts multimodal inputs, including text, images, and video, processed through its MoonViT (400M) vision encoder.
- In benchmarks, Kimi K2.6 achieved a score of 58.6% on SWE-Bench Pro, surpassing GPT-5.4 (57.7%) and Claude Opus 4.6 (53.4%).
