Musk said Grok 4.7 should be roughly equivalent to Opus 5.0, not 5.1, adding that it is stronger in some areas and weaker in others. He said multimodal performance still needs improvement, with Grok 4.8 expected to bring significant upgrades. Musk added that Grok 4.9 may reach the Astra/Fable level, while Grok 5 may surpass all current products.
