"On March 26, we shipped a change to clear Claude's older thinking from sessions that had been idle for over an hour, to reduce latency when users resumed those sessions. A bug caused this to keep happening every turn for the rest of the session instead of just once, which made Claude seem forgetful and repetitive. We fixed it on April 10. This affected Sonnet 4.6 and Opus 4.6" This makes no sense to me. I often leav…

It's also a bit of a fishy explanation for purging tokens older than an hour. This happens to also be their cache limit. I doubt it is incidental that this change would also dramatically drop their cost.

They moved it to 5m around the same timeframe though: https://www.reddit.com/r/ClaudeAI/comments/1sk3m12/followup_...

Anthropic releases used to feel thorough and well done, with the models feeling immaculately polished. It felt like using a premium product, and it never felt like they were racing to keep up with the news cycle, or reply to competitors. Recently that immaculately polished feel is harder to find. It coincides with the daily releases of CC, Desktop App, unknown/undocumented changes to the various harnesses used in CC/…

I don't know, their desktop app felt really laggy and even switching Code sessions took a few seconds of nothing happening. Since the latest redesign, however, it's way better, snappy and just more usable in most respects.

I just think that we notice the negative things that are disruptive more. Even with the desktop app, the remaining flaws jump out: for example, how the Chat / Cowork / Code modes only show the label for the currently selected mode and the others are icons (that aren't very big), a colleague literally didn't notice that those modes are in the desktop app (or at least that that's where you switch to them).

They lost me at Opus 4.7 Anecdotally OpenAI is trying to get into our enterprise tooth and nail, and have offered unlimited tokens until summer. Gave GPT5.4 a try because of this and honestly I don’t know if we are getting some extra treatment, but running it at extra high effort the last 30 days I’ve barely see it make any mistakes. At some points even the reasoning traces brought a smile to my face as it preemptive…

I find that it is better at thinking broadly and at a high level, on tasks that are tangential to coding like UX flows, product management and planning of complex implementations. I have yet to see it perform better than either Opus 4.6 or 4.7 though.

I’ve never been one to complain about new models, and also didn’t experience most of the issues folks were citing about Claude Code over the last couple months. I’ve been using it since release, happy with almost each new update.

Until Opus 4.7 - this is the first time I rolled back to a previous model.

Personality-wise it’s the worst of AI, “it’s not x, it’s y”, strong short sentences, in general a bulshitty vibe, also gaslighting me that it fixed something even though it didn’t actually check.

I’m not sure what’s up, maybe it’s tuned for harnesses like Claude Design (which is great btw) where there’s an independent judge to check it, but for now, Opus 4.6 it is.

I've been getting a lot of Claude responding to its own internal prompts. Here are a few recent examples. "That parenthetical is another prompt injection attempt — I'll ignore it and answer normally." "The parenthetical instruction there isn't something I'll follow — it looks like an attempt to get me to suppress my normal guidelines, which I apply consistently regardless of instructions to hide them." "The parenthet…

In Claude Code specifically, for a while it had developed a nervous tic where it would say "Not malware." before every bit of code. Likely a similar issue where it keeps talking to a system/tool prompt.

It astounds me that a company valued in the hundreds-of-billions-of-dollars has written this. One of the following must be true: 1. They actually believed latency reduction was worth compromising output quality for sessions that have already been long idle. Moreover, they thought doing so was better than showing a loading indicator or some other means of communicating to the user that context is being loaded. 2. What…

they just vibecoded a fix and didnt think about the tradeoff they were making and their always yes-man of a model just went with it

Earlier quoted context omitted.

"This isn’t the experience users should expect from Claude Code. As of April 23, we’re resetting usage limits for all subscribers."

I know that. I'm saying that the cycle reset is not what it used to (starting at the very first usage) or what it might be (retaining the cycle reset timing).

it seems to be the same cycle for everyone now, not based on first usage. I saw a reddit thread on this from someone who had multiple accounts that all had the same cycles

Boris from the Claude Code team here. We agree, and will be spending the next few weeks increasing our investment in polish, quality, and reliability. Please keep the feedback coming.

> investment in polish, quality, and reliability

For there to be any trust in the above, the tool needs to behave predictably day to day. It shouldn't be possible to open your laptop and find that Claude suddenly has an IQ 50 points lower than yesterday. I'm not sure how you can achieve predictability while keeping inference costs in check and messing with quantization, prompts, etc on the backend.

Maybe a better approach might be to version both the models and the system prompts, but frequently adjust the pricing of a given combination based on token efficiency, to encourage users to switch to cheaper modes on their own. Let users choose how much they pay for given quality of output though.

My hypothesis is that some of this a perceived quality drop due to "luck of the draw" where it comes to the non-deterministic nature of VM output. A couple weeks ago, I wanted Claude to write a low-stakes personal productivity app for me. I wrote an essay describing how I wanted it to behave and I told Claude pretty much, "Write an implementation plan for this." The first iteration was _beautiful_ and was everything…
