Today, we're expanding the Gemini 3 model family with the release of Gemini 3 Flash, which offers frontier intelligence built for speed at a fraction of the cost. With this release, we’re making Gemini 3’s next-generation intelligence accessible to everyone across Google products. Last month, we kicked off Gemini 3 with Gemini 3 Pro and Gemini 3 Deep Think mode, and the response has been incredible. Since launch day, we have been processing over 1T tokens per day on our API. We’ve seen you use Gemini 3 to vibe code simulations to learn about complex topics, build and design interactive games and understand all types of multimodal content . With Gemini 3, we introduced frontier performance across complex reasoning, multimodal and vision understanding and agentic and vibe coding tasks. Gemini 3 Flash retains this foundation, combining Gemini 3's Pro-grade reasoning with Flash-level latency, efficiency and cost. It not only enables everyday tasks with improved reasoning, but also is our most impressive model for agentic workflows. Starting today, Gemini 3 Flash is rolling out to millions of people globally: For developers in the Gemini API in Google AI Studio , Gemini CLI and our new agentic development platform Google Antigravity For everyone via the Gemini app and in AI Mode in Search For enterprises in Vertex AI and Gemini Enterprise

Gemini 3 Flash: frontier intelligence at scale Gemini 3 Flash demonstrates that speed and scale don’t have to come at the cost of intelligence. It delivers frontier performance on PhD-level reasoning and knowledge benchmarks like GPQA Diamond (90.4%) and Humanity’s Last Exam (33.7% without tools), rivaling larger frontier models, and significantly outperforming even the best 2.5 model, Gemini 2.5 Pro, across a number of benchmarks. It also reaches state-of-the-art performance with an impressive score of 81.2% on MMMU Pro, comparable to Gemini 3 Pro.

In addition to its frontier-level reasoning and multimodal capabilities, Gemini 3 Flash was built to be highly efficient, pushing the Pareto frontier of quality vs. cost and speed. When processing at the highest thinking level, Gemini 3 Flash is able to modulate how much it thinks. It may think longer for more complex use cases, but it also uses 30% fewer tokens on average than 2.5 Pro, as measured on typical traffic, to accurately complete everyday tasks with higher performance.

Gemini 3 Flash pushes the Pareto frontier on performance vs. cost and speed. Performance, here, is measured by LMArena Elo Score.

Gemini 3 Flash’s strength lies in its raw speed, building on the Flash series that developers and consumers already love. It outperforms 2.5 Pro while being 3x faster (based on Artificial Analysis benchmarking) at a fraction of the cost. Gemini 3 Flash is priced at $0.50/1M input tokens and $3/1M output tokens (audio input remains at $1/1M input tokens).

Gemini 3 Flash outperforms 2.5 Pro in speed and quality .

For developers: intelligence that keeps up Gemini 3 Flash is made for iterative development, offering Gemini 3’s Pro-grade coding performance with low latency — it’s able to reason and solve tasks quickly in high-frequency workflows. On SWE-bench Verified, a benchmark for evaluating coding agent capabilities, Gemini 3 Flash achieves a score of 78%, outperforming not only the 2.5 series, but also Gemini 3 Pro. It strikes an ideal balance for agentic coding, production-ready systems and responsive interactive applications.

Gemini 3 Flash’s strong performance in reasoning, tool use and multimodal capabilities is ideal for developers looking to do more complex video analysis, data extraction and visual Q&A, which means it can enable more intelligent applications — like in-game assistants or A/B test experiments — that demand both quick answers and deep reasoning.

Gemini 3 Flash enables multimodal reasoning in a hand-tracked "ball launching puzzle game" game providing near real-time AI assistance .

Gemini 3 Flash builds and A/B tests new loading spinner designs in near real-time , streamlining the design-to-code process.

Gemini 3 Flash uses multimodal reasoning to analyze and caption an image with contextual UI overlays in near real-time, ultimately transforming a static image into an interactive experience.

Gemini 3 Flash takes a single instruction prompt and codes three unique design variations .

We’ve received a tremendous response from companies using Gemini 3 Flash. Companies like JetBrains, Bridgewater Associates, and Figma are already using it to transform their businesses, recognizing how its inference speed, efficiency and reasoning capabilities perform on par with larger models. Gemini 3 Flash is available today to enterprises via Vertex AI and Gemini Enterprise.

For everyone: Gemini 3 Flash is rolling out globally Gemini 3 Flash is now the…
