[Musk: Grok 5 May Surpass All Current Products] Musk stated on social media: 'The level of Grok 4.7 should be roughly equivalent to Opus 5.0, but not 5.1. It is better in some aspects and weaker in others. We need to improve multimodal performance. Grok 4.8 will bring significant improvements. Grok 4.9 might reach the Astra/Fable level. Grok 5 may surpass all current products. Let’s wait and see.'
