They need to focus on fixing reliability first. Their systems constantly go down and it appears they are having to quantise the models to keep up with demand, reducing intelligence significantly. New features like this feel pointless when the underlying model is becoming unusable.

I wonder if their API model is different from the subscription model. People called me crazy saying how GitHub copilot is better than Clause code but since I started using Claude code these past 3 weeks, times and times again, copilot + Claude sonnet 4 is better

API has always been a little different.

Might be worth trying Claude through Amazon as well.

I regularly have this happen: 1. Ask Claude to fix something 2. It fails to fix the issue 3. I tell it that the fix didn’t work 4. It reverts its failed fix and tells me everything is working now. This is like finding a decapitated body, trying to bring it back to life by smooshing the severed head against the neck, realizing that didn’t bring them back to life, dropping the head back on the ground, and saying, “Ther…

Gosh, can't we get back to Sonnet 3.5 or whichever was the version around a year ago? It worked so well for me.

The same experience here: Claude with the pro plan over the summer was really doing a good job. The last 4 weeks? Constant slow-downs or API errors, more halucinating then before, and many mistakes. It appears to me that they are throttling to handle loads that they can't actually handle.

Last 4 weeks have been awful, I have barely used my max in comparison to the month before and it's an active deterrent to use it because you don't know if it's going to work or hit an unpredictable limit before getting to the bottom of getting something working.

I don't feel Claude would do this intentionally, and am reminded how I kept Claude for use for some things but not generally.

Have you run into the bug where claude acts as if it updated the artifact, but it didn’t? You can see the changes in real time, but then suddenly it’s all deleted character by character as if the backspace was held down, you’re left with the previous version, but claude carries on as if everything is fine. If you point it out, it will acknowledge this, try again, and… same thing. The only reliable fix I’ve seen is to…

Yes, this has been happening a lot more the past 8 weeks.

From troubleshooting Claude by reviewing it's performance and digging in multiple times why it did what it did, it seems useful to make sure the first sentence is a clearer and completer instruction instead of breaking it up.

As models optimize resources, prompt engineering seems to become relevant again.

I just published an extensive review of the new feature, which is actually Claude Code Interpreter (the official name, bafflingly, is Upgraded file creation and analysis - that's what you turn on in the features page at least).

I reverse-engineered it a bit, figured out its container specs, used it to render a PDF join diagram for a SQLite database and then re-ran a much more complex "recreate this chart from this screenshot and XLSX file" example that I previously ran against ChatGPT Code Interpreter last night.

Here's my review: https://simonwillison.net/2025/Sep/9/claude-code-interpreter...

It works for me on the https://claude.ai web all but doesn't appear to work in the Claude iOS app. I tried "Tell me everything you can about your shell and Python environments" and got some interesting results after it ran a bunch of commands. Linux runsc 4.4.0 #1 SMP Sun Jan 10 15:06:54 PST 2016 x86_64 x86_64 x86_64 GNU/Linux Ubuntu 24.04.2 LTS Python 3.12.3 /usr/bin/node is v18.19.1 Disk Space: 4.9GB total, with 4.…

This can't be understated. I started using it heavily earlier this summer and it felt like magic. Someone signing up now based on how I described my personal experiences with it then would think I was out of my mind . For technical tasks it has been a net negative for me for the last several weeks. (Speaking of both Claude Code and the desktop app, both Sonnet and Opus >=4, on the Max plan.)

Thanks for the confirmation. Lately it's been telling me it has made edits or written code yet it's nowhere to be seen. It's been messing up extremely simple tasks like "move this knob from the bottom of the screen to the right". Over and over it will insist it made the changes but it hasn't. Getting confused about completely different sections of code and files.

I picked up Claude at the beginning of the summer and have had the same experience.

I don’t think you’re crazy, something is off in their models. As an example I’ve been using an MCP tool to provide table schemas to Claude for months. There was a point where it stopped recognizing the tool unless mentioned in early August. Maybe that’s related to their degraded quality issue. This morning after pulling the correct schema info Sonnet started hallucinating columns (from Shopify’s API docs) and added t…

I have read so many anecdotes about so many models that "were great" and aren't now.

I actually think this is psychological bias. It got a few things right early on, and that's what you remember. As time passes, the errors add up, until the memory doesn't match reality. The "new shiny" feeling goes away, and you perceive it for what it really is: a kind of shitty slot machine

> personally am frustrated that there’s no refund or anything after a month of degraded performance

lol, LMAO. A company operates a shitty slot machine at a loss and you're surprised they have "issues" that reduce your usage?

I'm not paying for any of this shit until these companies figure out how to align incentives. If they make more by applying limits, or charge me when the machine makes errors, that's good for them and bad for me! Why should I continue to pay to pull on the slot machine lever?

It's a waste of time and money. I'll be richer and more productive if I just write the code myself, and the result will be better too.

I hesitate to use phrases like "bait and switch" but it seems like every model gets released and is borderline awe-inspiring, then as adoption increases, and load increases, it's like it gets hit in the head with a hammer and is basically useless for anything beyond a multi-step google search.

I think it's a psychological bias of some sort. When the feeling of newness wears off and you realize the model is still kind of shit, you have an imperfect memory of the first few uses when you were excited and have repressed the failures from that period. As the hype wears off you become more critical and correctly evaluate the model

Would anyone agree with my experience that OpenAI has the most robust and reliable LLM ecosystem atm? One week I really like Gemini 2.5 pro, the next I thought Claude was better, a few days I thought Grok 4 was pretty good (grok 4 is the most inconsistent "model"). But at the end, I default to OpenAI for overall consistency and reliability.
