AI Provider Configuration

OpenQA supports multiple LLM providers.

Anthropic (Default)

Claude is the default provider with two authentication methods:

claude login

Uses Claude Code authentication. No API key needed.

export ANTHROPIC_API_KEY=sk-ant-...

Or in .env:

ANTHROPIC_API_KEY=sk-ant-...

Use GPT models via LangChain agent:

# .env
AGENT_TYPE=langchain
DEFAULT_PROVIDER=openai
OPENAI_API_KEY=sk-...

Or pass options directly:

await runAgent("Click submit", context, {
  agentType: "langchain",
  provider: "openai",
  model: "gpt-4o"  // optional
});

Use Gemini models via LangChain agent:

# .env
AGENT_TYPE=langchain
DEFAULT_PROVIDER=google
GOOGLE_API_KEY=...

Or pass options directly:

await runAgent("Click submit", context, {
  agentType: "langchain",
  provider: "google",
  model: "gemini-1.5-pro"  // optional
});

Configuration is resolved in this order:

// This overrides all env vars
await runAgent("Click", context, {
  agentType: "langchain",
  provider: "openai"
});
