On September 14, Musk revealed on a social platform that the performance of Grok 4.7 is roughly comparable to that of Opus 5.0, rather than 5.1, with both having their own strengths and weaknesses in performance. He stated that there is a need to improve Grok's multimodal capabilities. Grok 4.8 will see significant enhancements, 4.9 may reach the level of Astra/Fable, and Grok 5 is expected to surpass all existing products, which is something to look forward to.
