How to Install / Upgrade: SpaceXAI releases Grok 4.6, claiming GPT-5.6 Sol and Claude Fable 5-level…

What happened

SpaceXAI released Grok 4.6 and says the model has intelligence comparable to OpenAI GPT-5.6 Sol and Anthropic Claude Fable 5. The release follows the Cursor acquisition and the Grok Bot agent release from the day before, as SpaceXAI works to repair Grok’s reputation and get more serious about its models.

The technical detail

To move to this release, switch your Grok usage to Grok 4.6 from SpaceXAI. If you run agent workflows, use the Grok Bot agent that SpaceXAI released with this same effort. If you work in a coding environment, use Cursor after the SpaceXAI acquisition so Grok 4.6 sits with the rest of that product set.

Market and competitive context

The comparison to GPT-5.6 Sol and Claude Fable 5 is SpaceXAI’s claim as reported by 9to5Mac, so treat it as a vendor claim until you check it on your own work. Confirm the Grok 4.6 release, the Cursor acquisition, and the Grok Bot agent release against that 9to5Mac report before you change production traffic. SpaceXAI is still in the process of repairing Grok’s reputation, so verify the new model on a real task after you switch.
