Grok Bot Backend Upgrade Swaps in Anthropic's Claude Opus 5.5
The change replaces SpaceXAI and Cursor's models with Claude for Grok Bot's intelligence, according to 9to5mac.com.
Grok Bot has received a backend upgrade that lets the app use Anthropic's Claude Opus 5.5 model to power its intelligence, according to 9to5mac.com. The change replaces SpaceXAI and Cursor's models with Claude.
Grok Bot runs on iPhone, iPad and Mac. The upgrade applies to the backend rather than to a new app release, so the apps themselves continue to be distributed through the same platforms.
The switch puts Anthropic's Claude Opus 5.5 behind a product that until now relied on models from SpaceXAI and Cursor for its intelligence.
Earlier releases
Grok Bot launched in August with dedicated apps for the iPhone and iPad, and an iPad version plus more affordable plans arrived in September 2025. Anthropic became a SpaceX customer this year as it shopped for compute to power Claude usage.
