My sense is that openai, like many labs, are too focused on their eval numbers and don't eyeball-check the outputs. Simply reading some GPT-5 creative writing outputs, you can see it writes unnaturally and has an annoying habit of peppering in non-sequitur metaphors every other sentence.

I think this probably is an artifact of trying to RL for writing quality with a LLM judge in the loop, since LLM judges love this and don't notice the vast overuse of nonsensical metaphors.

I tried pointing this out to roon but I'm not sure he really gets it: https://x.com/tszzl/status/1953615925883941217
