Claude s Opus 5 is a recent model and has been very problematic as a drop-in replacement for Opus 4.8, including ignoring our well-documented deploy process (clearly described in our short claude.md file and short architecture file) and breaking production immediately upon being activated.Currently, I added a supervisor layer where an Opus 4.8 instance supervises Opus 5 and corrects it. It helped a little. I am thinking of downgrading to Opus 4.8 but want to give Opus 5 a chance.Do you think this model will improve or will it stay stuck at its current level of capabilities?You can see complaints from other people:https://www.reddit.com/r/ClaudeAI/comments/1v92csh/opus_5_extremely_rlfried_and_mistakeprone_for/ Opus 5 is truly not good for any task, imo. i have thoroughly tried it in every possible role in a large, complicated project. it is bad for all tasks. Claudebot s summary of the thread: The overwhelming consensus in this thread is that Opus 5 is a buggy, overconfident mess and a significant regression from Opus 4.8 for complex coding.
