Grok 4.5 has become the leader among AI agents for browser-based work: a new standard of autonomy
The market for AI agents capable of independently interacting with web pages is developing rapidly. This is not just about chatbots, but about full-fledged assistants that can open websites, click buttons, fill out forms, and collect data — from booking tickets to complex web scraping. And, as recent tests show, the Grok model from xAI has surged ahead in this segment, leaving giants like OpenAI and Anthropic behind.
Gregor Zunic, founder of the Browser Use service, conducted a comparative analysis of five tools, evaluating them on a key parameter: the percentage of successfully completed tasks on real websites without errors. Here, Grok demonstrated an outstanding result — 76.42% successful operations. This places it in first place, ahead of OpenAI's assistant (72.70%) and two agents from Anthropic (70.75% and 67.92%). Closing the ranking is GPT via the OpenClaw plugin with a score of 60.38%.
Why did Grok prove to be more effective?
The key factor is the artificial intelligence model itself that makes decisions. In this comparison, Grok runs on Grok 4.5, while competitors use GPT 5.5 and Opus 4.8. It is the AI's "brains" that determine how correctly the agent interprets the task, reacts to dynamic content, and corrects errors on the fly. It is important to note that even with the same developer, as in the case of Anthropic, the method of connecting to the browser can affect the result — the difference was nearly three percentage points.
This test clearly demonstrates that the AI agent race is just beginning, and leadership can change with the release of each new model version. For users, this means the emergence of increasingly reliable tools for automating routine online operations.
Expert commentary: The AI agent market is essentially a new battle for the user's "periphery." Grok 4.5 proves that xAI is capable not only of catching up but also of setting trends in the practical application of AI. For the crypto community, this is especially important: autonomous agents could become the foundation for a new generation of DeFi interfaces and analytics tools, where speed and accuracy of command execution are crucial.
