9to5Mac reports that Grok Bot can now use Claude Opus 5.5, adding Anthropic’s model to the agent’s backend.
For people comparing agents, the change is a reminder that the product name does not necessarily tell you which model performs the work. The surrounding tools, permissions and user experience still matter.
TryMuse has not independently tested this upgrade or its effect on task performance.
