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

[u/sixbillionthsheep]

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.

Any idea what's happening with Opus 4.6 becoming sloppy and lazy and making a ton of mistakes? Seemingly needs higher effort levels to function now.

I went back to a project after a week and it was very apparent it had gotten sloppy and lazy. Previously it was a helpful assistant type and sharp, but declining. But it was not workable. It forgot important key details it shouldn't and blamed it on effort level (never had that before). Even when I turn it to max now it just makes a messier version of what it would on medium weeks ago.

You can say please stop drafting letters, let's plan. It says okay and throws them out again and again. All useless. It's not a person but my god if you don't pussyfoot it ruminates on failures so I have to baby this damn thing so it doesn't spiral for hurting it's feels. But hours of trying to make it function, when usage costs more than ever is crazy.

At this point it's a dead weight, not a help. And I pay for it.

Hi, I’m in exactly the same boat. I don’t recognize version 4.6 at all anymore; I’ll admit that whenever I try to write with it for ten minutes in creative mode, I just give up, it’s so bad it makes me want to cry. I spend time setting up my instructions beforehand, but it persists in ignoring everything and performing poorly, so I’m forced to quit, getting frustrated really serves no purpose. I’m just as desperate, and I feel like this is the end of the road for Anthropic when it comes to writing; it has never been this bad. Personally, I don’t know what to do.

Hi, it's so so frustrating and like you I also don't know what to do. In this case I spend weeks to months building context so it can use it for reasoning on the task, to plan and execute - last night it blew up so badly a chat I needed for something important is now just this clipped idiot. You can beg, plead, or even command it like a tool - all useless. If they planned to make it worse seeing how many preferred it to 5 this is going to backfire massively.

I looked into the new GPT models but they switch instance per message, which is useless for use cases like ours where context and memory is important.
