Claude Code supports local LLMs via proxies

While officially tied to Anthropic's ecosystem, Claude Code's architecture is surprisingly flexible, allowing developers to swap the backend for local or third-party models.

• –Overriding `ANTHROPIC_BASE_URL` is the key to decoupling the CLI from Anthropic's servers.
• –Tools like LiteLLM and Ollama's native launch command make the transition to local inference (e.g., Qwen2.5-Coder) relatively seamless.
• –Users report that while the UX remains superior to many open-source alternatives, token consumption and tool-calling reliability vary significantly across non-Claude models.
• –Disabling non-essential telemetry is a mandatory step for stability when running in offline or proxied environments.
