Grok 4.5 surpasses competitors in browser management: Browser Use test results
Modern AI assistants are rapidly evolving: they no longer just answer questions but are capable of independently visiting websites and performing actions on behalf of the user—opening pages, clicking buttons, filling out forms, and collecting data. Simply give a command, such as "book a ticket" or "gather information from a portal," and the neural network does everything on its own.
A recent comparative study conducted by Gregor Zunic, founder of the Browser Use service, showed that among five tested AI tools, the assistant based on the Grok model delivered the best results. The key metric was the accuracy of task completion on websites without errors. The higher the score, the more reliable the tool in real-world use.
The leader was Grok with an impressive result—76.42% of tasks correctly completed. Next came the assistant from OpenAI with a score of 72.70%. Two tools from Anthropic took third and fourth places with results of 70.75% and 67.92%, respectively. Bringing up the rear was GPT via the OpenClaw plugin—only 60.38%.
What Lies Behind the Numbers
Each assistant operates on its own underlying AI model: Grok uses the Grok 4.5 model, OpenAI tools use GPT 5.5, and Anthropic solutions use Opus 4.8. It is the model—the "brain" of the assistant—that makes decisions and thinks, while the assistant itself merely adds the ability to control the browser. The results clearly show that, given equal interface choices, the quality of the model becomes the decisive factor. Grok 4.5 confidently outperforms all competitors.
It is also important to note that the method of connecting to the browser affects the final accuracy. For the same assistant from Anthropic, the difference in results was nearly three percentage points depending on the integration method. This indicates that optimizing the "wrapping" around the model is no less critical a task.
My analysis: The market for AI assistants for web automation is entering a phase of maturity, and Grok 4.5's leadership is a serious signal for the entire industry. xAI's technology is not only catching up but also outperforming the giants in a key scenario—practical interaction with the internet. For the crypto community, this is especially important: autonomous agents capable of working with DeFi protocols and exchanges are becoming increasingly realistic.
