Grok 4.6 Spotted in Cursor Then Pulled, Unconfirmed by xAI
On Aug 11, multiple users spotted Grok 4.6 in Cursor's model picker, but it was quickly pulled, leaving only a non-clickable option. The listing showed 256k context and a 'strongest model' tag, yet xAI has released no official info. The incident fuels speculation about rapid iteration.
Confirmed
- Grok 4.6 briefly appeared in Cursor's model picker on Aug 11, showing 256k context and a 'strongest model' tag, according to user reports.
- The model was subsequently rolled back, leaving only a non-clickable option.
Unconfirmed
- Whether the model is fully developed and imminent. @eyishazyer found no official info, and rumored specs like 1.5T parameters and 1M context lack official basis.
- Whether this was an accidental early deployment by Cursor or a small-scale test by xAI remains undetermined.
Why it matters
- If Grok 4.6 launches within weeks, it would mark a major acceleration in xAI's iteration pace, less than a month after Grok 4.5.
- Developers have praised Grok 4.5's capability and efficiency, raising expectations for the new version.
