Claude Code can run entirely on your local GPU now.

Unsloth AI published the complete guide.

The setup itself is straightforward - llama.cpp serves Qwen3.5 or GLM-4.7-Flash, one environment variable redirects Claude Code to localhost.

But the guide is valuable because of what it explains beyond the setup:

Why local inference feels impossibly slow: Claude Code adds an attribution header that breaks KV caching. Every request recomputes the full context. The fix requires editing settings.json - export doesn't work.

Why Qwen3.5 outputs seem off: f16 KV cache degrades accuracy, and it's llama.cpp's default. Multiple reports confirm this. Use q8_0 or bf16 instead.

Why responses take forever: Thinking mode is great for reasoning but slow for agentic tasks. The guide shows how to disable it.

The proof it all works: Claude Code autonomously fine-tuning a model with Unsloth. Start to finish. No API dependency.

Fits on 24GB. RTX 4090, Mac unified memory.

The cold is a teacher. It’s merciless. You don’t picnic when you go into the cold. You don’t think about your mortgage or your kid’s braces or your divorce; you just survive. You reactivate the deepest part of your brain.
