Theo: xAI just caught up — Grok 4.6 on the Intelligence Index

Thursday, 13 August 2026 12:36 pm BST · GrokBotNews0

Theo (t3.gg) walks Grok 4.6: Artificial Analysis Intelligence Index 61, five points over 4.5, more tokens per run. That 61 is a third-party chart, not an xAI system card. Watch the video.

Theo is reviewing a public model drop. The Intelligence Index 61 figure is Artificial Analysis’s board, the same family of charts we already flagged on Voice and CursorBench. GrokBotNews has not re-run the index. xAI’s own post says 4.6 is for long-running agents — that is the vendor claim.

The video is from 13 Aug, a day after Grok 4.6 landed in Cursor, Grok Build, and the API. Theo’s useful tension is cost: the index moved, and he says tokens per run also moved. A higher score at 30% more tokens is not the same story as a free lunch.

If you only watch one reviewer clip on 4.6, this is the one with a named host and a chart you can go check. Then read the x.ai post. Then try a long agent job yourself.

    Daniel Kokotajlo on The Diary Of A CEO

    Former OpenAI researcher Daniel Kokotajlo tells Steven Bartlett why he walked away from a reported $2 million, and why he puts a high probability on extremely large AI effects this decade. His numbers are forecasts, not measurements.

    Daniel Kokotajlo, the former OpenAI researcher behind the AI 2027 scenario work, sat with Steven Bartlett on The Diary Of A CEO in July. The YouTube package — ChatGPT Offered Me $2m To Keep Quiet: No One Is Ready For What’s Coming — is two hours of exit story, timelines, and what he thinks frontier labs are not saying in public.

    The useful split is the same one this site uses on model charts. “I left, and this is why” is testimony. “There is a 70% chance of X by year Y” is a forecast. Testimony can be true while the forecast is wrong. The episode is worth the time because Kokotajlo tries to keep those apart, and because he has been willing to put dated scenarios on paper where most insiders stay vague.

    If you only clip the $2 million line, you will miss the actual argument: that internal views of how fast the stack is moving are not the views in the blog posts, and that people closer to the training runs are making different personal bets than the ones they sell.
