Elon Musk revealed the Grok iteration roadmap in a reply:
- Grok 4.7: roughly on par with Claude Opus 5.0 (not 5.1), better in some ways, worse in others; multimodal performance needs fixing
- Grok 4.8: a noticeable improvement
- Grok 4.9: probably Astra/Fable class
- Grok 5: "maybe better than anything. We shall see."
A rare firsthand statement on capability gradients from xAI's core figure, useful as a reference for generational model competition.
