Models and API keys

Settings → AI model lets you choose Claude Code or Codex. The selected engine builds and edits Studio projects. Changing the engine starts a fresh agent session, but keeps the same project files and chat.

Poko credits work without provider keys and route supported models for you. Bring your own key is entitlement-gated and enables direct provider billing. Settings are locked while an agent is running.

For Claude Code, an Anthropic API key takes priority over a connected Claude subscription. For Codex, an OpenAI API key takes priority over a connected ChatGPT subscription. Personal subscription connections and custom gateways require eligible Pro or Agency plans.

Claude Code requires an Anthropic Messages-compatible endpoint. Codex requires an OpenAI Responses-compatible endpoint. A Chat Completions-only server is not compatible with either of these gateway modes.

Background music and sound effects continue to consume Poko credits even when an AI model uses your own key. Check your selected billing mode before generation.
