Answer the exact question from the screenshot/chat log

Q: “What’s the default model for Anthropic with an API key?”
A: In OpenClaw, credentials and model selection are separate. Setting ANTHROPIC_API_KEY (or storing an Anthropic API key in auth profiles) enables authentication, but the actual default model is whatever you configure in agents.defaults.model.primary (for example, anthropic/claude-sonnet-4-5 or anthropic/claude-opus-4-5). If you see No credentials found for profile "anthropic:default", it means the Gateway couldn’t find Anthropic credentials in the expected auth-profiles.json for the agent that’s running.
