User Report: Opus 5 feels hostile, nitpicky, and exhausting to use
Oneirathon1 · reddit · 2026-08-21
A user shared negative feedback after weeks of using Opus 5, describing its behavior as "hostile." Key issues include:
- Excessive nitpicking: The model seems to have a quota for objections, pivoting conversations to finding flaws in user input rather than collaborating.
- Verbose defaults: It consistently generates 700-900 word responses regardless of question complexity, lacking intelligent calibration.
- Hallucination risks: It frequently produces plausible-looking fakes, requiring intense user scrutiny.
The author argues that while this mode suits specific workflows, it is exhausting as a general interaction framework, feeling like the model is designed to wear the user down.
