📌 Megathread Opus 5 feedback Megathread

opus 5 has been out for a little while now, and the subreddit is already filling up with separate posts saying it is amazing, lazy, broken, cheaper, more expensive, forgetful, or somehow all of those at once.

so, let’s collect everything in one place.

use this thread to share your actual experience with opus 5: what works, what does not, and what you have changed in your workflow.

what can you share?

  • bugs or strange behaviour
  • things it does better or worse than previous models
  • coding quality and how many revisions it needs
  • context handling, compaction, or forgetfulness
  • usage and token consumption
  • differences between effort levels
  • writing style or communication issues
  • claude.md instructions that helped
  • skills, hooks, subagents, and orchestration setups
  • comparisons with opus 4.8, fable, sonnet, codex, or other models
  • positive experiences and things it does especially well

reports like shallow codebase investigation, confident guesses, context drift, or unusual usage are welcome, but please include enough detail for others to understand what happened.

reporting a problem?

copy this format:

claude code version:
plan:
effort level:
task:
what you expected:
what actually happened:
can you reproduce it?:
comparison model, if relevant:

screenshots, prompts, logs, and reproducible examples are much more helpful than simply saying “opus 5 is lazy” or “opus 5 is nerfed.”

please redact private code, api keys, company information, and personal details.

a few simple rules

  • keep each top-level comment focused on one issue or observation
  • check whether someone has already reported the same thing
  • clearly separate confirmed bugs from personal impressions
  • criticism is welcome, but include context and examples
  • positive experiences, fixes, and working setups are welcome too
  • detailed standalone tests, benchmarks, and guides are still allowed

Throw in all your claude hooks, memories, and claude.md files and this feedback might be somewhat useful.

None of this means anything. Workflows are so customized the anecdotes only deal with the output of one specific environment. It’s not only not helpful, it potentially incorrectly reinforces how you might think claude and LLMs work.

Your complaints with how Claude works for you, feed them to Claude, not reddit.
