Start building free
gemini-3.1-flash-lite is a lightweight, cost-optimized member of Google’s Gemini 3.1 family, designed for very fast, inexpensive inference in applications that need high request volume or must run on more constrained hardware. It sits below the general Gemini 3.1 Flash tier in size and capability, trading some raw reasoning depth and multimodal sophistication for lower latency and better efficiency. Typical uses include high-traffic chatbots, simple agents, UI helpers, autocomplete, and other tasks where responsiveness and throughput matter more than advanced creativity or complex multi-step reasoning. It is generally intended as a practical, production-friendly workhorse model rather than a flagship frontier system.

Every request must include an Authorization: Bearer <TOKEN> header. Generate a token from your account's API Keys page — its access to models is set automatically from your active plans and redeemed codes, and you can set its rate limit and IP restrictions.
| Parameter | Type | Description |
|---|---|---|
model | string, required | This model's ID, exactly as shown above. |
messages | array, required | Conversation history as role/content objects (system, user, assistant). |
temperature | number, optional | Sampling randomness, typically 0–2. |
max_tokens | integer, optional | Upper limit on tokens generated in the reply. |
top_p | number, optional | Nucleus-sampling threshold, as an alternative to temperature. |
stream | boolean, ignored | Responses are always returned in full so the exact cost can be billed; streaming is not available. |
