Models & Research

xAI Releases Grok 4.6 With a Focus on Long-Running Agents — xAI has released Grok 4.6, a successor to Grok 4.5 built for multi-step agentic work and interactive or visual projects. xAI reports a score of 61 on the Artificial Analysis Intelligence Index, matching GPT-5.6 Sol Max and trailing Fable 5 Max at 62. The model is available now in Cursor, Grok Build, and the xAI API, starting at 2 US dollars per million input tokens and 6 US dollars per million output tokens. arXiv ↗

My takeaway: Grok 4.6 matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index, both at 61, and runs cheaper per task at $0.84 against $1.23. Plenty of models cost less, but among those scoring 61 or above, Grok 4.6 is the cheapest. I think price is the model's strongest selling point. It is worth evaluating for your own use cases.
