A GPU count, not a benchmark score

In the posts we checked, he backed it with a GPU count and a growth-rate line, not a benchmark score.

“Elon Musk posted on X that he is cautiously optimistic SpaceX will have a Fable/GPT-6 level AI model in 2 to 3 months, and that SpaceX will reach 'pole position' in about 6 months, as headlined by Yahoo Finance.”

Nothing in the posts we checked ties either number to a benchmark score or a released model. What Musk offered was a GPU count, with Colossus 2 headed toward 1.2 million Blackwell GPUs by year end per Electronics Weekly, and a comparison of how many years each lab has existed.

The twist

Wccftech reported that Musk told China Media Group catching up to the frontier was most likely next year, not in months, and Benzinga reported that he agreed a chart ranking Grok behind Anthropic and OpenAI's models was accurate, adding for now.

Say this in tomorrow's meeting“Musk did not publish a benchmark behind the 2-to-3-month or 6-month calls. He also told China Media Group that catching up to the frontier was most likely next year, and he agreed a chart ranking Grok behind Anthropic and OpenAI was accurate, for now.”
