Gemini CLI will limit free users to the Flash model starting March 25, as announced by Ryan J. Salva, Head of the Gemini CLI product. This change is part of three new policy updates revealed on GitHub. Free users will lose access to Pro models, which will now require a paid Google AI subscription, starting at $19.99 per month for AI Pro and $249.99 per month for AI Ultra. Additionally, traffic will be prioritized based on license type and account status, potentially leading to capacity limits for some users during peak times. The service has also enhanced its abuse detection system, focusing on preventing unauthorized use of Gemini CLI OAuth authentication with third-party software. Developers are encouraged to obtain their own paid API keys through AI Studio or Vertex AI to manage quotas and billing independently.
