Nervos Expert

Fine-tuned LLMs that know Nervos CKB — cell model, scripts, Fiber, JoyID, light client, and the ecosystem. Running entirely in your browser via WebGPU.

Your browser does not support WebGPU. See browser setup below.
Browser Setup Guide (WebGPU required)

Chrome / Edge 113+ — Works out of the box. If not, enable at chrome://flags/#enable-unsafe-webgpu

Brave — Enable brave://flags/#enable-unsafe-webgpu and brave://flags/#enable-vulkan. Install vulkan-tools on Linux. Restart after enabling flags.

Safari 17+ (macOS / iOS) — WebGPU is enabled by default. Must be served over HTTPS (not http:// or file://). Private Browsing mode disables the Cache API which prevents model downloads.

Firefox — WebGPU is behind a flag. Enable dom.webgpu.enabled in about:config. Nightly builds recommended.

iOS Chrome / iOS Firefox — These use Safari's WebKit engine under the hood. WebGPU availability depends on iOS Safari support, not the browser app itself.

Linux (NVIDIA) — Ensure vulkan-tools is installed: sudo apt install vulkan-tools. Verify with vulkaninfo --summary.

How it works

Models are downloaded once to your browser cache via WebGPU. All inference runs locally on your GPU — no data leaves your device.

Training data

Fine-tuned on CKB RFCs, official docs, Fiber protocol specs, JoyID documentation, community posts, and open-source CKB codebases.

POC status

This is an early proof of concept. Answers may contain inaccuracies. The training data is AI-generated and has not yet undergone human review.

Source

Models, training scripts, and evaluation results are open source on GitHub and Hugging Face.
