SpaceXAI seems to be in the process of repairing Grok’s reputation. From the recent Cursor acquisition to yesterday’s Grok Bot agent release, the company is getting more serious about its models. Today’s Grok 4.6 release builds on that effort with what SpaceXAI says is intelligence comparable to OpenAI’s GPT-5.6 Sol and Anthropic’s Claude Fable 5.
SpaceXAI says Grok 4.6 delivers frontier intelligence at a steep discount
According to SpaceXAI’s announcement, Grok 4.6 is designed for long-running agents, coding, knowledge work, and more ambitious visual projects.
The company says it can stay on task across many steps, work through an unfamiliar codebase, and increasingly test its own output before moving forward.
On the Artificial Analysis Intelligence Index, Grok 4.6 scored 61. That matches GPT-5.6 Sol at its maximum reasoning level and trails Fable 5 Max by one point.
