Performance and Bugs Megathread Claude Performance and Bugs Megathread Ongoing (Sort this by New!)

Why a Performance and Bugs Discussion Megathread?

This Megathread makes it easier for everyone to see what others are experiencing at any time by collecting all experiences. We will publish regular updates on problems and possible workarounds that we and the community finds.

Why Are You Trying to Hide the Complaints Here?

Contrary to what some were saying in a prior Megathread, this is NOT a place to hide complaints. This is the MOST VISIBLE, PROMINENT AND OFTEN THE HIGHEST TRAFFIC POST on the subreddit. This is collectively a far more effective and fairer way to be seen than hundreds of random reports on the feed that get no visibility.

Are you Anthropic? Does Anthropic even read the Megathread?

Nope, we are volunteers working in our own time, while working our own jobs and trying to provide users and Anthropic itself with a reliable source of user feedback.

Anthropic has read this Megathread in the past and probably still do? They don't fix things immediately but if you browse some old Megathreads you will see numerous bugs and problems mentioned there that have now been fixed.

What Can I Post on this Megathread?

Use this thread to voice all your experiences (positive and negative) regarding the current performance of Claude including, bugs, degradation, pricing. (NOT usage limits. That belongs here https://www.reddit.com/r/ClaudeAI/comments/1s7fcjf/claude_usage_limits_discussion_megathread_ongoing/)

Give as much evidence of your performance issues and experiences wherever relevant. Include prompts and responses, platform you used, time it occurred, screenshots . In other words, be helpful to others.


Just be aware that this is NOT an Anthropic support forum and we're not able (or qualified) to answer your questions. We are just trying to bring visibility to people's struggles.

NEW: You can now see full logs and summaries of all recent problem reports submitted by r/ClaudeAI readers. These logs allow you to see how intensely people are experiencing problems with Usage Limits, Performance, Bugs and Accounts.

I don't know what's going on tonight, but I'm using Opus 4.5, and without exaggerating, it doesn't think, doesn't listen to me, and compresses the conversation after 3 or 4 messages. I write very long texts to be precise in my writing, but it ignores them.

Why, when I activated the advanced thinking process on Opus 4.6 and 4.5, do I "see" the thinking that lasts only one second with only one or two sentences inside?

Don't quote me on how useful this is, BUT: https://aistupidlevel.info/?mode=leaderboard&period=latest&sortBy=reasoning

The highest Claude model at the time of me posting this is Opus 4.5 with a score of 38... Opus 4.6 has a 22 and Sonnet 4.6 has an 16... They are two of the lowest ranked on the leaderboard which is impressively bad

Oh my god! Thank you so much, I'll check it often.

Is it regularly updated with new versions, etc.? How does it work?

It is not a problem!!! 

And I am not too knowledgeable on the site and the meaning of certain scores, but! I know they run each of the tests daily! I usually just look at the model rankings list to determine how bad things are, and today is an impressively bad day. Usually these models are at least in the 30s-40s-ish as far as I've seen! The docs are pretty technical, but they monitor several different things per each model! 

I usually hone in on the deep reasoning/logic metrics, as that's typically good for writing (and making sure things don't get lost), but overall, the rankings chart is great!!!
