Model Provider Quickstart: Connect and Configure LLMs

Learn how to connect a model provider to OpenClaw, complete authentication, and set your default model using the provider/model format. This page suits anyone configuring an LLM for the first time.

Read this when

  • You want to choose a model provider
  • You want quick setup examples for LLM auth + model selection

Select a provider, complete authentication, then assign the default model using provider/model.

Quick start (two steps)

  1. Log in to your chosen provider (typically through openclaw onboard).
  2. Define the default model:
{
  agents: { defaults: { model: { primary: "anthropic/claude-opus-4-6" } } },
}

Supported providers (starter set)

The complete list of providers plus settings for advanced use cases lives in Provider directory and Model providers.

Additional provider variants

  • anthropic-vertex - install @openclaw/anthropic-vertex-provider to get implicit Anthropic support on Google Vertex. That capability kicks in whenever Vertex credentials exist. No dedicated auth option appears during onboarding.
  • copilot-proxy - a local bridge to the VS Code Copilot Proxy. Use openclaw onboard --auth-choice copilot-proxy.
  • google-gemini-cli - an optional explicit runtime for canonical google/* models. A local gemini install is needed, along with a supported Google AI Studio API-key profile. Setting up Gemini CLI or Antigravity OAuth from scratch is not available.
