Grok 4.7 mocked for overconfidence; Musk's fix is turning on xhigh mode

teortaxesTex · x · 2026-09-23

User teortaxesTex jokes that Grok 4.7 isn't the best model this week by any means, but "feels THE BEST about itself." The quoted context notes the team may have penalized response length too much in RL, so the model still gives up on hard tasks it can actually do. Elon Musk's solution: Grok 4.7 xhigh and Grok Build. More of an AI-circle meme, but it surfaces the length-penalty tuning issue behind models abandoning hard problems early.
