Agree with “PACE THE FRONTIER” in public. Keep training.
The 2.5T Grok 4.8 model is going to be better than the current non-public models from Anthropic & OpenAI.
I think Grok 4.7 will be in the same category as Fable 5.1 & Astra. That’s probably why he’s delayed the release twice.

Grok 4.7 should be roughly on par with Opus 5.0, not 5.1. Better in some ways, worse in others. We need to fix multimodal performance.
Grok 4.8 will be a noticeable improvement.
Grok 4.9 is probably Astra/Fable class.
Grok 5 maybe better than anything. We shall see.
