Capabilities, design details, and architectural traits
Gemini 3.1 Flash Lite - high-volume multimodal model
Gemini 3.1 Flash Lite is built for high-frequency tasks that need low latency. It is framed as a lightweight model for scale, with controls for thinking and structured task handling.
| Distinctive trait | What is documented |
|---|---|
| High-volume focus | Optimized for high-frequency, lightweight tasks and high-volume traffic. |
| Multimodal inputs | Supports text, image, video, audio, and PDF inputs. |
| Thinking control | Supports thinking, with selectable thinking levels in AI Studio and Vertex AI. |
| Task routing use | Documented for model routing, where it can classify task complexity. |
Scale pattern
The model is described as a lightweight option for straightforward work at scale. Documented uses include translation, transcription, data extraction, document processing, and routing tasks.
Supported workflow
Its API documentation also lists function calling, structured outputs, code execution, file search, search grounding, URL context, and Google Maps grounding. The model is presented as a practical choice when speed and throughput matter more than broad general-purpose depth.
