Good to know before you start

  • Free tiers are for trying things. Most limit requests per minute or per day, and some are not licensed for business use.
  • Some free tiers learn from your prompts. Google and Mistral say free usage may be used to improve their models. Do not paste anything private.
  • Hit a limit? Wait a minute, switch the panel to another free provider, or read Quota and rate limit errors.
  • Your keys stay yours. They are saved only in your browser and go straight to the provider with each message.
