Gemini 3 Flash Preview
VerifiedGoogle's fast multimodal model for text, image, audio and video tasks.
About Gemini 3 Flash Preview
Gemini 3 Flash Preview belongs to Google's Gemini model family and emphasizes low latency while supporting multiple input types. Its architecture integrates vision, audio and language capabilities into a single system that handles long contexts efficiently. As a preview release, it offers early access to these features ahead of wider deployment.
The model is not open-weight, keeping its parameters proprietary to Google. Strengths include native handling of diverse modalities and a large context window that allows processing of lengthy documents or extended media sequences. These traits make it suitable for applications requiring both speed and broad input support.
Typical usage covers real-time chat interfaces, media analysis tools and content generation pipelines that combine text with visual or audio data. Developers integrate it via Google's APIs to build assistants or automation workflows that benefit from its multimodal reach.

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-3-flash-preview",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: google/gemini-3-flash-preview
