elonmusk · x · 2026-07-13
Elon Musk stated that the publicly available version of Mythos (Fable, with Claude as a fallback) is "noticeably nerfed," though it's the only version most people can access right now.
He added that Grok 4.5 is slightly higher than Fable on some software benchmarks, and that Fable itself is already a "very good model."
