Puck(@GrokInsider):Elon just laid out the Grok ladder through 5. • 4.7 roughly on par with Opus 5.0, not 5.1 (multimodal still needs work) • 4.8 a noticeable step up • 4.9 Astra / Fable class • 5 maybe better than anything That's a harder ceiling on 4.7 than a lot of people were pricing in.

@itslueul 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.
