LM Studio can act as a direct replacement for Anthropic's servers when running Claude Code.

LM Studio version 0.4.1 introduced a special translation feature. It mimics Anthropic's own communication style, known as the messages endpoint. By changing a few settings on your computer, you tell the Claude command tool to talk to your local machine instead of the internet. This lets you run local models like Qwen or Gemma. It is like redirecting a phone call from a long-distance office to your neighbor next door.
