xAI drops Grok 4.6 and Grok Bot, a strong new entrant in the AI teammate race

[AINews] SpaceXAI Grok 4.6 and Grok @Bot

xAI launched Grok 4.6 and the Grok Bot early beta. Grok Bot logs into your tools, operates them like a human, and returns finished work—positioned as an AI teammate. The 1.5T-parameter Grok 4.6 scores near GPT-5.6 Sol Max on the AA-Briefcase knowledge-work benchmark but costs far less: $2/M input tokens, $6/M output. Training reused Grok 4.5 to regenerate SFT traces and added agentic RL across coding, web, CAD, and kernel optimization. Elon says Grok 4.7 is already training. The same day, Qwen3.8-Max dropped as open weights: a 2.4T total / 95B active MoE.

Why it matters: Grok 4.6 matches GPT-5.6 Sol Max on a knowledge-work benchmark at an order-of-magnitude lower price, while the simultaneously launched Grok Bot enters the AI teammate race built by the ex-Cursor team with positive early feedback. Score isn't higher because the Bot is still in ...

xAI dropped two things on the same day: Grok 4.6, a 1.5T-parameter model that scores near GPT-5.6 Sol Max on the AA-Briefcase knowledge-work benchmark, and Grok Bot, an early beta that logs into your tools, operates them like a human, and returns finished work.

The model's pricing is the headline: $2/M input tokens, $6/M output. Training reused Grok 4.5 to regenerate SFT traces and added agentic RL across coding, web dev, CAD, and kernel optimization. I'd discount the benchmark claims a bit—the AA-Briefcase test set is private, and xAI shared very little training detail.

Grok Bot is positioned as an AI teammate. Early reviews are more positive than what Claude Tag and Block's Buzz got at launch. The real test will be reliability and permissions at scale—it's still early beta.

Same day, Qwen3.8-Max shipped as open weights: a 2.4T total / 95B active MoE. The model layer is racing toward capable-and-cheap; the Bot layer is racing toward "AI that does the work for you."
