Grok 4.6
On SpaceX’s June earnings call, Elon highlighted that the upcoming Grok 4.6 would yield meaningful advancement in intelligence. That’s exactly what happened 8 days later when the new model went live. Within a day, the model showed its best performance on the AI leaderboard, highlighted by Artificial Analysis’s Intelligence Index, which is considered the gold standard, ranking Grok 4.6 in 4th place, behind Claude Opus 5, Claude Fable 5, and GPT-5.6 Sol.
The reason for the improvements fell into the category of training improvements and was not the result of the inclusion of Cursor or SpaceX data. The bottom line is the improvements to Grok 4.6 were a function of general model advancements, rather than the inclusion of key new data.
