Original Reddit post

For the last 24 hours – five different sessions, Sonnet continually ellipses instructions, changes requirements, or otherwise takes various shortcuts. When asked, it claims it did the work. It completed a specific requirement. But it’s just lying. Only when shown proof will it admit that it skipped requirements. Of course apologize, then offer to fix it. But it again takes a shortcut there. Amending the spec file doesn’t fix the issue. Adding a memory doesn’t help. I never believe LLM when they explain why, but it claims certain phrases in its system instructions make it rush to finish at all costs. Just a rant. Sorry. But I’m at the point where I’m going to use GLM after work to see if I get better compliance. (Codex limit has been reached.) submitted by /u/Illustrious-Many-782
