Google Officially Launches Gemini 3 Series Models for Gemini CLI Users

Google has officially announced the launch of its latest Gemini 3 series models for Gemini CLI users, including Gemini 3 Pro and Gemini 3 Flash. This release is available to all paid tier users, such as Google AI Pro or AI Ultra subscribers, as well as users accessing via paid API keys. Free users who previously registered for Gemini 3 preview access can now also directly use these two models. The newly introduced Gemini 3 Flash model is the most efficient model to date, helping users learn, build, and plan faster, balancing professional-grade coding capabilities with low latency to support daily development workflows. Users need to update their Gemini CLI to the latest version 0.21.1, ensure preview features are enabled, and use the /model command to route tasks or rely on automatic routing for simple tasks. Google provides detailed documentation links and GitHub repository support to help developers solve problems and explore applications of these cutting-edge AI technologies.
