Providers

One provider interface, many sign-in methods. Subscriptions and API keys coexist, and switching model or reasoning effort is a command away.

Signing in

/auth registers a provider. Subscriptions sign in through a browser device flow; API providers take a key. Built in: ChatGPT Codex subscription, Gemini Code Assist subscription, Grok subscription, Nous Research subscription, Fireworks AI, Anthropic API (pay-per-token), OpenRouter (pay-per-token), OpenCode (zen/go), and Mistral AI. Any other OpenAI-compatible endpoint can be registered from the REPL.

Models and effort

The default model is gpt-5.6-sol. Through the Codex provider, gpt-6-astra is also available with a 272,000-token context window. /models lists what is registered, /model picks one together with its reasoning effort, /effort changes the effort alone, and /fast toggles Codex Fast mode. /trace shows visible reasoning summaries, and /info reports the current model and runtime settings.

Where credentials live

Sign-in tokens and API keys are kept in your user configuration, outside saved cores, conversation files, and Git.
