"Support" is defined as the same level of support that the current Grok models have. Available for business plans with zero data retention.
Will resolve when Grok 4.1 Fast is retired on the API OR Cursor supports it.

Hey all.
Thanks for the feedback.
For the moment, we don’t have plans to add Grok 4.1, though you might find Grok Code Fast 1 works well for your needs—it’s xAI’s model explicitly built for coding tasks!
Grok Code, as of today, is also free for users of Cursor.

My comment from the linked forum post:
> It seems to me at this point it must be a business decision to not add the model. Perhaps xAI is not extending their zero data retention agreement for Grok 4.1 Fast or something. Maybe with the release of Composer, xAI views Cursor as a competitor and is being uncooperative.
