Claude Code

Claude Code and similar AI coding CLIs (aider, Continue.dev, Cursor) can use mycellm as their LLM backend via the OpenAI-compatible API.

Environment setup

Section titled “Environment setup”
Terminal window
export OPENAI_BASE_URL=http://localhost:8420/v1
export OPENAI_API_KEY=your-mycellm-key

Then run your coding CLI as normal — it will route through mycellm.

How it works

The coding CLI thinks it’s talking to OpenAI. mycellm routes the request to the best available model on the network — could be a local GGUF model, a QUIC-connected peer, or a fleet node.

Model selection

Section titled “Model selection”

For coding tasks, you may want to specify a capable model:

Terminal window
export OPENAI_MODEL=Mistral-Small-24B-Instruct-2501-Q4_K_M

Or use mycellm’s quality routing:

{
  "mycellm": {
    "min_tier": "capable",
    "required_tags": ["code"]
  }
}

Running headless

Section titled “Running headless”

If your mycellm node is on a remote GPU server:

Terminal window
# On the GPU server
mycellm serve --host 0.0.0.0


# On your laptop
export OPENAI_BASE_URL=http://gpu-server:8420/v1
claude-code  # or aider, continue, cursor, etc.

Other coding tools

Section titled “Other coding tools”

The same env vars work with any OpenAI-compatible coding tool:

  • aider — export OPENAI_API_BASE=http://localhost:8420/v1
  • Continue.dev — set base URL in VS Code extension settings
  • Cursor — custom API endpoint in settings
  • Tabby — configure as OpenAI-compatible backend
