Musk Claims that Grok-4 is Better Than Cursor

Elon Musk led ​​xAI has launched Grok 4 and Grok 4 Heavy, two versions of its latest AI model. The company described Grok 4 as a single-agent version, while Grok 4 Heavy is the multi-agent version. 

CEO Musk took to X to claim that Grok-4 outperforms the AI coding tool Cursor.

“You can cut & paste your entire source code file into the query entry box on grok.com and Grok 4 will fix it for you!” he said in a post on X. “This is what everyone at xAI does. Works better than Cursor,” he added. 

As announced by Musk, the company also plans to launch a coding model focused on being “both fast and smart,” expected to be released in a few weeks.

Both models are available immediately and come bundled with access to Super Grok tiers, where users can direct a network of Grok agents to assist with research and productivity.

Grok 4 is also accessible via API, and xAI claims the model leads key reasoning benchmarks, including ARC-AGI-2.

Meanwhile, over the past few days, users have been cancelling their Cursor subscriptions en masse, voicing outrage over what they see as an abrupt and poorly communicated change, particularly to the company’s heavily promoted “unlimited” Pro plan.

Users claim that Cursor’s Pro plan, which once promised unlimited usage, has effectively been capped. “Cursor constantly changing their pricing without any proper announcement or documentation recently is a pretty bad and frustrating move for users,” said one user.

Cursor has issued a clarification, admitting they “missed the mark” with the updated pricing and are fully refunding affected users. But that hasn’t quelled the criticism, as Reddit threads are filled with complaints that go beyond pricing alone.
