Polpo supports 22+ LLM providers out of the box. Pick a provider, set the API key, then use provider:model in your config.

Quick Start

  1. Set the API key or login via OAuth:
export ANTHROPIC_API_KEY=sk-ant-...
  1. Reference the model in your agent config:
{
  "agents": [
    { "name": "coder", "model": "anthropic:claude-sonnet-4-6" }
  ]
}
For full details on model format, resolution order, and fallback chains, see Overview. For OAuth setup and auth profiles, see Authentication.
