Gemini 2.5 Flash Lite
VerifiedGoogle's fast, lightweight multimodal model for text, image, audio, and video tasks.
About Gemini 2.5 Flash Lite
Built as a streamlined member of the Gemini family, the model prioritizes speed and resource efficiency while supporting multiple input types. Its architecture enables simultaneous handling of text, images, audio, and video within one large context window. This design suits scenarios where rapid multimodal integration is required without open-weight access.
Strengths center on balanced performance for real-time applications and large-scale input processing. Typical usage includes content analysis, media summarization, and interactive tools that combine visual, auditory, and textual data streams in a single query.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "google/gemini-2.5-flash-lite",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: google/gemini-2.5-flash-lite
