Gemini 3 has been released and is progressively being made available to Gemini Code Assist users in VS Code and IntelliJ. Initially, Gemini 3 is only being made available in agent mode.
Once enabled, Gemini Code Assist tries to use Gemini 3 unless otherwise configured using the model selector (VS Code only). When Gemini Code Assist tries to use Gemini 3, it falls back to other models, such as Gemini 2.5 Pro, if capacity is unavailable or quotas are exceeded. Responses include a label when they are generated using Gemini 3.
