Use Claude subscription access from Pi when you want Claude models alongside Pi's normal workflow.
Select a klaus/* model and keep using Pi normally for prompts, tools, sessions, and UI.
Start
Install or update through Installation, then restart Pi after rebuilding.
Log in to Anthropic in Pi with /login, then choose a klaus/* model in /model.
Klaus needs Pi-managed Anthropic OAuth, so API-key-only Anthropic sign-in cannot use it.
/model
# choose klaus/claude-sonnet-…
/klaus-setup-token opens an Anthropic sign-in flow and gives you a long-lived OAuth token.
Use it only when you need that token, and treat the displayed or copied token like a password.
What to expect
Klaus shows current Claude model families available through Pi instead of dated snapshot IDs.
Your normal Pi conversation continues when switching or compacting sessions.
Claude Fable can consume separate Anthropic usage credits in some account configurations.
