Google bets its next AI wave on agents, not chatbots, with Gemini 3.5 Flash

Google on Tuesday launched Gemini 3.5 Flash, a new AI model that the company says is its strongest yet for coding and autonomous AI agents. Introduced at the annual I/O developer conference, the model can independently execute coding pipelines, manage research projects, and, in internal tests, build an operating system entirely from scratch. The release signals a clear strategic shift: Google is moving beyond conversational chatbots toward AI as an agentic tool — one that plans, builds, and iterates on real work with minimal human input.

Speed and performance at the core

According to Koray Kavukcuoglu, DeepMind’s chief technologist, Gemini 3.5 Flash offers a combination of quality and low latency that outperforms Google’s previous frontier model, 3.1 Pro, on nearly all benchmarks, including coding, agentic tasks, and multimodal reasoning. The model is four times faster than other frontier models, and an optimized version runs 12 times faster while maintaining the same quality. That speed is central to Flash’s design for agentic work, where multiple AI agents operate simultaneously on long-running tasks.

Antigravity: A native environment for agents

Kavukcuoglu said Flash 3.5 was co-developed with Antigravity, Google’s agentic development platform and IDE, to provide a native environment where agents can live, work, and execute. At I/O, Google released Antigravity 2.0 as a standalone desktop application designed around agent-first development. During a demonstration, Google engineer Varun Mohan showed agents spawning off to work on separate components before coming together to build a full operating system inside Antigravity.

Real-world impact and safety considerations

Google says 3.5 Flash’s agentic capabilities are already showing results among partners, including banks and fintechs automating multi-week workflows and data science teams finding insights in complex data environments. The model can run autonomously for multiple hours, though Tulsee Doshi, Google’s senior director and head of product, said it will pause and ask for user input when it hits decision points or permission issues requiring human judgment. Google also emphasized that Gemini 3.5 has strengthened cyber and CBRN safeguards and is better calibrated to engage with sensitive questions rather than refuse them outright. The safety updates come amid ongoing scrutiny, including a lawsuit related to a Gemini user incident last year.

What this means for consumers and developers

Gemini 3.5 Flash is now the default model in the Gemini app and in AI Mode in Search globally. At I/O, Google also announced agentic capabilities coming to Search, letting users create, customize, and manage AI agents directly on the platform. The new model will also power Gemini Spark, Google’s personal AI agent designed to run 24/7 to help consumers manage their digital life. When Google releases its forthcoming 3.5 Pro model, the two are designed to work in tandem: 3.5 Pro as the orchestrator and planner, and Flash as the sub-agents handling specific tasks.

Conclusion

With Gemini 3.5 Flash, Google is making a clear bet that the next wave of AI will be defined by autonomous agents, not conversational chatbots. The combination of speed, agentic capability, and integration with platforms like Antigravity and Search positions the company to lead in this emerging category. However, the broader availability of powerful autonomous agents also raises important questions about safety and oversight — questions Google says it is addressing through strengthened safeguards and human-in-the-loop design. Gemini 3.5 Flash is available today via Antigravity, the Gemini API, Gemini Enterprise, the Gemini app, and AI mode in Search.

FAQs

Q1: What is Gemini 3.5 Flash?
A: It is Google’s latest AI model, optimized for coding and autonomous agent tasks. It can execute multi-step projects independently and is significantly faster than previous models.

Q2: How is this different from previous Gemini models?
A: Gemini 3.5 Flash is designed for agentic work — planning, building, and iterating with minimal human input — rather than just answering questions like a chatbot. It also offers major speed improvements and outperforms the previous 3.1 Pro model on most benchmarks.

Q3: Where can I access Gemini 3.5 Flash?
A: The model is available through Antigravity, the Gemini API, Gemini Enterprise, the Gemini app, and AI mode in Google Search globally.
