Google DeepMind Launches Gemini 3.1 Flash-Lite, Its Cheapest Model Yet

Google DeepMind released Gemini 3.1 Flash-Lite, positioning it as the most cost-efficient model in the Gemini 3 series — aimed squarely at high-volume, latency-sensitive API applications.

Google DeepMind shipped Gemini 3.1 Flash-Lite on Tuesday, describing it as "our most cost-efficient Gemini 3 series model," as @GoogleDeepMind announced. The release targets developers building applications where per-token cost and response latency matter more than peak reasoning ability — classification tasks, structured extraction, lightweight chat, and similar high-volume use cases.
