Google Launches Gemini 3 Flash, Its Fastest AI Model Yet, With High Performance at Low Cost

Google has unveiled Gemini 3 Flash, its fastest AI model to date, designed to process text, images, audio, and video instantly. Optimized for low latency and cost-efficiency, the model is particularly suited for real-time applications, coding tasks, and agent-based workflows.

Multimodal and Superfast Reasoning
Gemini 3 Flash supports multimodal inputs, enabling it to provide immediate results based on multiple data types. This feature makes the model ideal for applications ranging from coding to complex analysis. Low latency ensures faster responses, while optimized costs make it accessible for a wide range of users. Gemini 3 Flash is now the default engine in the Gemini app as well as the AI mode in Google Search.

AI-Generated Fake Video Detection
With the rise of AI-generated fake videos, distinguishing real content from manipulated videos has become challenging. To address this, Gemini 3 Flash includes a new feature that identifies videos created or edited using Google AI tools. Users simply upload a video and query the model, which checks for a digital marker called Synth ID. This feature supports videos up to 100 MB and 90 seconds in length and is available globally across all languages.

Default Model and Enhanced Features
The Gemini app now uses Gemini 3 Flash as its default model. Users can still select a Pro model for advanced tasks in mathematics, coding, and complex queries. The model can interpret multimodal content—images, tables, audio—and provide precise responses. For example, users can upload a short pickleball video to get tips for improving their game, submit sketches for analysis, or upload audio recordings for quizzes and insights.

Prototype Apps From Simple Prompts
One of the standout features of Gemini 3 Flash is its ability to create app prototypes from simple prompts. The model understands user intent more effectively and generates answers enriched with visual elements such as images and tables, allowing users to rapidly prototype apps without coding.

With Gemini 3 Flash, Google has pushed the boundaries of AI, combining speed, versatility, and accessibility, making it a powerful tool for developers, creators, and everyday users alike.
