Elon Musk has reiterated a rather shocking tidbit about xAI’s impressive scores at the ARC-AGI benchmark.
He also announced that xAI’s upcoming model, Grok 5, will begin training very soon.
xAI results on the ARC-AGI benchmark
In a recent post on social media platform X, Greg Kamradt, President of the ARC Prize Foundation, noted that Grok 4 has been used in two SOTA submissions to the ARC-AGI V1 and V2 benchmarks. The submissions, which were the best that the foundation has encountered to date, were done using xAI’s large language model, Grok 4.
As per Kamradt, when asked about why the submissions were done using Grok 4, the authors stated that “It was the best model I used in testing.” Musk was evidently proud of this accomplishment, though he also highlighted that these accomplishments were attained with just Grok 4. This suggests that once Grok 5 is in the picture, xAI’s lead in the AI sector could become notable.
That’s just Grok 4 https://t.co/KCgZLdPkPG

Grok 5 incoming
Elon Musk has shared a number of tidbits about Grok 5 as of late. In recent comments on X, the Tesla and SpaceX CEO stated that he believes Grok 5 has the potential to actually reach artificial general intelligence (AGI). This suggests that Grok 5 would be nothing short of a monster, as it could be capable of matching or surpassing human-level intelligence across tasks such as thinking, reasoning, and other domains by a substantial margin.
Grok 5 may also be coming soon. As per Musk in another post on X, xAI will be starting the training of Grok 5 in a few weeks. Musk definitely seems to be highly optimistic about the capabilities of Grok 5, with the CEO stating late last month that the update would be coming before the end of the year and that it will be “crushingly good.”
