Grok 4.6, the new flagship from SpaceXAI, is built for agents that stick with a task across many steps, and the company released it the same week its Grok Bot service put always-on AI workers on their own cloud computers.
SpaceXAI, which used to operate under the xAI name, priced the model at $2 per million input tokens and $6 per million output. It went live August 12 in Cursor, Grok Build, and the API. The company says its Artificial Analysis Intelligence Index score of 61 ties OpenAI’s GPT-5.6 Sol, trails Anthropic’s Fable 5 Max by a point, and leaves Grok 4.5 High at 56. On DeepSWE v1.1, the coding benchmark, it improved from 54 to 65.9 percent.
Grok Bot, in beta since August 11, gives each agent a cloud computer plus access to the apps and websites a customer already uses. Bots handle multi-step jobs without supervision, message each other in group chats, and can be taught a routine by watching a human do it once. The service is bundled into SuperGrok Heavy, Cursor Ultra at $200 a month, and Cursor Teams Premium at $120 a seat.
The launch puts SpaceXAI against OpenAI’s ChatGPT Work, Anthropic’s Claude Cowork, and Microsoft’s Copilot Tasks in the race to sell digital labor rather than chat.
