Google I/O 2026: Gemini 3.5 Flash and Search agents turn AI into a business platform

Google used its stage on I/O 2026 to strengthen commitment to corporate artificial intelligence. With the launch of Gemini 3.5 Flash** and the integration of native agents into Search, the search giant bets on a more agile and accessible ecosystem for companies and developers. The news, reported by Yahoo Finance, position Gemini as an agent platform — not just a language model.

Gemini 3.5 Flash: What has changed for companies?

The highlight was Gemini 3.5 Flash**, an optimized version for tasks that require low latency and reduced cost. For businesses running large-scale applications, this means processing more requests with less computational expenditure. Google has promised up to 40% cost reduction per token compared to previous generation, making it feasible to use in support chatbots, stream automation, and real-time data analysis.

In addition, the model was designed to function as a core of autonomous agents** — systems that perform multiple stages without human intervention. This connects directly with the strategy of transforming Gemini into an AI operating system for companies.

AI agents on Search: How will they work?

For the first time, Google tests agents that run actions directly on search results**. For example, when searching for “booking a flight to São Paulo for the weekend”, the agent can access airline systems, compare prices and complete the booking — all within the results page. The functionality will be gradually released to Google One AI Premium users.

The Gemini 3.5 Flash model is the engine behind these agents. It combines multimodal reasoning with ability to call external APIs, which allows you to interact with third party platforms in a secure manner. Google stated that agents follow strict privacy and user consent policies.

Gemini 3.5 Flash: Why does it matter to Brazilian developers?

With cost reduction and the opening of APIs to create customized agents, startups and technology companies in Brazil gain a powerful tool to automate processes without relying on their own infrastructure. Google released the SDK from the Gemini Agent Framework in beta version, which allows you to create, test and deploy agents with few lines of code.

The movement aligns itself with other initiatives of the sector, such as Microsoft launches Rampart and Clarity, which also seeks to democratize the safe use of AI. For Brazilian developers, the availability of cheaper models and integration with local services — such as payment and logistics systems — can accelerate adoption in sectors such as retail and finance.

Gemini 3.5 Flash vs. competitors: how do you compare?

In internal benchmarks released at the event, the Gemini 3.5 Flash surpassed equivalent OpenAI and Anthropic models in mathematical reasoning and code generation tasks, with speed up to three times higher. Google also announced that the model will be available on Vertex AI, its machine learning platform, with a price per token up to 30% lower than the GPT-4th mini.
