xAI releases Grok 4.6, targeting agentic tasks and trading benchmark leads

By PulseAugur Editorial · [1 sources] ·

xAI has released Grok 4.6, a model designed for long-running agents and complex interactive tasks, rather than a raw intelligence leap. The company claims it matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index and trades leads with GPT-5.6 Sol and Fable 5 on other benchmarks, though it shows weaknesses in areas like real terminal work. Pricing for Grok 4.6 starts at $2 per million input tokens and $6 per million output tokens, with a faster version available at double the cost. AI

IMPACT This release signals a continued focus on agentic capabilities and benchmark competition among frontier models.
