Musk Admits Grok 4.7 Trails Anthropic's Opus 5.5, Expects Frontier Catch-Up Next Year

Elon Musk made the rare admission that his own Grok 4.7 ranks second: it trails Anthropic's newest Opus 5.5, he says, because xAI has been building AI for only 3 years versus Anthropic's 6. He expects Grok to reach the frontier most likely next year.

Commenters noted how unusual it is for a founder to rank his own model second — and argued that if the catch-up lands, the best model for your agent changes again, so keep the model a config line, not a rewrite.
