Our Computer Use model is a specialized model built on Gemini 2.5 Pro’s capabilities to power agents that can interact with user interfaces, Available in preview via the Gemini API in Google AI Studio and Vertex AI.
Earlier this year, we mentioned that we're bringing computer use capabilities to developers via the Gemini API. Today, we are releasing the Gemini 2.5 Computer Use model, our new specialized model built on Gemini 2.5 Pro’s visual understanding and reasoning capabilities that powers agents capable of interacting with user interfaces (UIs). It outperforms leading alternatives on multiple web and mobile control benchmarks, all with lower latency. Developers can access these capabilities via the Gemini API in Google AI Studio and Vertex AI.
While AI models can interface with software through structured APIs, many digital tasks still require direct interaction with graphical user interfaces, for example, filling and submitting forms. To complete these tasks, agents must navigate web pages and applications just as humans do: by clicking, typing and scrolling. The ability to natively fill out forms, manipulate interactive elements like dropdowns and filters, and operate behind logins is a crucial next step in building powerful, general-purpose agents.
How it works
The model’s core capabilities are exposed through the new \computer_use\ tool in the Gemini API and should be operated within a loop. Inputs to the tool are the user request, screenshot of the environment, and a history of recent actions. The input can also specify whether to exclude functions from the full list of supported UI actions or specify additional custom functions to include.

The model then analyzes these inputs and generates a response, typically a function call representing one of the UI actions such as clicking or typing. This response may also contain a request for an end user confirmation, which is required for certain actions such as making a purchase. The client-side code then executes the received action.
After the action is executed, a new screenshot of the GUI and the current URL are sent back to the Computer Use model as a function response restarting the loop. This iterative process continues until the task is complete, an error occurs or the interaction is terminated by a safety response or user decision.
The Gemini 2.5 Computer Use model is primarily optimized for web browsers, but also demonstrates strong promise for mobile UI control tasks. It is not yet optimized for desktop OS-level control.

How it performs
The Gemini 2.5 Computer Use model demonstrates strong performance on multiple web and mobile control benchmarks. The table below includes results from self-reported numbers, evaluations run by Browserbase and evaluations we ran ourselves. Evaluation details are available in the Gemini 2.5 Computer Use System Card and in Browserbase’s blog post. Unless otherwise indicated, scores shown are for computer use tools exposed via API.

How we approached safety
We believe that the only way to build agents that will benefit everyone is to be responsible from the start. AI agents that control computers introduce unique risks, including intentional misuse by users, unexpected model behavior, and prompt injections and scams in the web environment. Thus, it is critical to implement safety guardrails with care.
We have trained safety features directly into the model to address these three key risks (described in the Gemini 2.5 Computer Use System Card).
Further, we also provide developers with safety controls, which empower developers to prevent the model from auto-completing potentially high-risk or harmful actions. Examples of these actions include harming a system's integrity, compromising security, bypassing CAPTCHAs, or controlling medical devices. The controls:
- Per-step safety service: An out-of-model, inference-time safety service that assesses each action the model proposes before it’s executed.
- System instructions: Developers can further specify that the agent either refuses or asks for user confirmation before it takes specific kinds of high-stakes actions. (Example in documentation).
Additional recommendations for developers on safety measures and best practices can be found in our documentation. While these safeguards are designed to reduce risk, we urge all developers to thoroughly test their systems before launch.
How early testers have used it
Google teams have already deployed the model to production for use cases including UI testing, which can make software development signficantly faster. Versions of this model have also been powering Project Mariner, the Firebase Testing Agent, and some agentic capabilities in AI Mode in Search.
Users from our early access program have also been testing the model to power personal assistants, workflow automation, and UI testing, and have seen strong results. In their own words:
“A lot of our workflows require interacting with interfaces meant for humans where speed is especially important. Gemini 2.5 Computer Use is far ahead of the competition,
often being 50% faster and better
than the next best solutions we’ve considered.”

“Our agents run fully autonomously, performing work where small mistakes in collecting and parsing data are unacceptable. Gemini 2.5 Computer Use outperformed other models at reliably parsing context in complex cases,
increasing performance by up to 18%
on our hardest evals.” —
