Gemini 3 Flash

Gemini 3 Flash launched on December 17, 2025 as the speed-optimized sibling of the Gemini 3 Pro flagship. Google positioned it as delivering frontier-class performance at a fraction of the cost and latency, and it became the default model in the Gemini app shortly after launch. It is available across the Gemini API, AI Studio, Vertex AI, and Gemini Enterprise.

Flash is aimed at real-time and agentic workloads: chatbots, virtual assistants, and coding agents that need fast iteration loops. Third-party coverage of Google's launch materials notes upgraded visual and spatial reasoning plus agentic coding capabilities, with multimodal function responses and code execution with images among the new API features. It handles text, code, and images with up to a 1M-token context window.
