Gemini 3 Flash Preview is Google's high-speed, high-value thinking model, released on 2025-12-17 for agentic workflows, multi-turn chat, and coding assistance. It delivers near Pro-level reasoning and tool-use performance with substantially lower latency than larger Gemini variants, which suits interactive development, long-running agent loops, and collaborative coding. Compared with Gemini 2.5 Flash it improves broadly across reasoning, multimodal understanding, and reliability, and it accepts image, audio, video, and PDF input alongside function calling, prompt caching, and web search. Context window: 1M tokens, output: 64K. Available via OpenAI and Gemini protocols.
