Google has unveiled Gemini 3 Flash, a faster and more cost-efficient model built on last month’s Gemini 3 release. It has become the default model in the Gemini app and Google Search’s AI mode, fully replacing Gemini 2.5 Flash.
The new model delivers a significant performance boost and, in several benchmarks, approaches flagship systems such as Gemini 3 Pro and GPT-5.2. On Humanity’s Last Exam, which measures cross-domain expertise without tool use, Gemini 3 Flash scored 33.7%, compared with just 11% for its predecessor. It also achieved the top result on the multimodal MMMU-Pro benchmark, scoring 81.2%.
Gemini 3 Flash is positioned as a fast, multimodal workhorse model. It supports video, image, audio, and sketch analysis, better interprets user intent, and generates more visually rich responses, including tables and images. In the Gemini app, the model can also be used to create application prototypes through prompts.
For enterprises and developers, Gemini 3 Flash is available via Vertex AI, Gemini Enterprise, and a preview API and is already used by companies such as JetBrains and Figma. Pricing is set at $0.50 per million input tokens and $3.00 per million output tokens. While slightly more expensive than Gemini 2.5 Flash, Google says the model offers higher speed, more efficient token usage, and better suitability for large-scale workloads.
