Gemini Flash
Lightweight models, two variants, both optimized for speed and efficiency
Lightweight, fast and cost-efficient models featuring multimodal reasoning and a breakthrough long context window of up to one million tokens.
Small, smaller
Flash now comes in two compact variants, giving you the flexibility for whatever you choose to build.
Performance in a flash
Designed to be fast and efficient to serve at scale.
-
Built for speed
Sub-second average first-token latency for the vast majority of developer and enterprise use cases.
-
Quality at lower cost
On most common tasks, 1.5 Flash models achieve comparable quality to larger models, at a fraction of the cost.
-
Long-context understanding
Process hours of video and audio, and hundreds of thousands of words or lines of code.
Longer context
Flash models have a one-million-token context window by default, which means you can process one hour of video, 11 hours of audio, codebases with more than 30,000 lines of code, or over 700,000 words.
Relentless innovation
Our research team is continually exploring new ideas at the frontier of AI, building innovative products that show consistent progress on a range of benchmarks.
