Anthropic Engineer Weighs In as Users Say Opus 5.5 Won Them Back from Codex

Anthropic engineer Boris Cherny replied agreeing that Opus 5.5 is a good model. User kimmonismus praised Opus 5.5 as the best model he's used — good taste, comparatively fast, smart, and finally precise instead of verbose — and said he's eager for 'Fable 5.5.' After switching entirely to OpenAI's Codex, he says he now has to go back to Anthropic, noting how quickly sentiment on X has flipped in the model's favor.
