October 2026

October 15, 2026

  • System Zero launch System Zero makes text decisions with boolean, choice and score questions. Existing users and people with a current invitation can sign in and manage keys under API keys. For more information, see Quickstart.
  • Playground launch Run a System Zero decision in Playground without pasting an API key. Open an example in your workspace's Playground, edit the state and questions, then run it. For more information, see Playground.
  • Billing and credits status The API is not charged, and the console takes no payment while billing is closed. Workspace usage limits still apply. For more information, see Billing and credits.
