I don't mind too much about ChatGPT's writing style, I find it a smidge better than the Fable/Opus outputs I have read.

However, it makes me rather frustrated when it says stuff like "You accidentally <did, stumbled on, implemented, etc> <something good>" e.g "You accidentally stumbled on the cleanest way!"

Or when it sends a shell command to run, and when it fails (due to a hallucinated flag or similar), it phrases it as if I got it wrong...this has gotten better with GPT-5.6, thankfully.
