About Gemini 3.5 Flash
Learn about Gemini 3.5 Flash's capabilities, features, and how it can help you achieve better results.
High-Efficiency Agentic Performance
Gemini 3.5 Flash is a multimodal model designed for speed and complex reasoning. It supports a 1-million-token context window, enabling users to process massive data sets including hour-long videos and entire code repositories in a single prompt. The architecture is optimized for sub-second latency, targeting developers building interactive AI agents and automated workflows.
Native Multimodality and Reasoning
This model introduces a Thinking mode for advanced chain-of-thought logic. It natively processes text, images, audio, video, and PDFs, which removes the need for separate preprocessing pipelines. Benchmarks indicate that it outperforms the previous Gemini 3.1 Pro in coding and tool-use tasks while maintaining the efficiency of the Flash tier.
Production-Ready Scaling
At a cost of $1.50 per million input tokens, it provides a cost-effective path for high-volume applications. It is specifically tuned for function calling and terminal-based tasks, achieving high scores on agentic benchmarks like SWE-bench and Terminal-Bench. This makes it a primary choice for real-time coding assistants and data curation systems.

Use Cases

Community Feedback
See what the community thinks about Gemini 3.5 Flash
“Gemini 3.5 Flash is the clear leader on the Intelligence vs Speed Pareto frontier and makes large gains on real-world agentic tasks.”
“Gemini 3 is brilliant for UK business use. It captures nuanced politeness levels and UK-specific tax assumptions better than US-centric models.”
“This model is so like it loves music stuff. It is very, very fast and the audio synthesizer it generated had me completely sold.”
“Gemini 3.5 Flash is definitely outperforming the previous Pro model on coding related things, which is huge for agentic developers.”
“Google just released Gemini 3.5 Flash. The interesting part is not just that it’s faster. Google is positioning this as the agentic king.”
“Gemini 3.5 Flash is super strong model for its class. Beats Gemini 3.1 Pro on so many benchmarks.”

“Gemini 3.5 Flash has been released from Google. And this is hypothetically a pretty big leap in performance.”
“This is the best one that I've seen, period. Even if it doesn't work, this model is so like it loves music stuff.”
“I noticed it is very, very fast and it really does seem to like music.”
“The reasoning capabilities for such a small, fast model are genuinely impressive during these code tests.”
“It managed to create a working three-dimensional synth environment from a single prompt without errors.”
“Gemini 3.5 Flash completely shocked me. Not only was it insanely fast but it actually completed the task better than Opus.”
“Gemini 3.5 Flash finished this task within a minute. This is really insane. The speed of Gemini 3.5 Plus is insane.”
“Gemini 3.5 Flash did it in just $0.36, whereas Claude Opus did it in almost double price.”
“The multi-modal understanding here is clearly a step up from the previous Flash version.”
“You are getting near flagship intelligence for a fraction of the token cost.”
“This is a model that's positioned as Google's strongest agentic coding model yet, above the Gemini 3.1 Pro.”
“The quality jump is very noticeable. Hallucination rates have reportedly reduced from 91% to 61% which is remarkable.”
“Gemini 3.5 Flash excels obviously for its price and quality SVG art as well as working in 3JS.”
“It natively processes video and audio, allowing for much more accurate extraction of temporal data.”
