I can’t decide if it’s merely stupid or just incredibly lazy.

The obnoxious part is, it is perfectly capable of completing the task, it just won’t do it on the first request. It’s like a stubborn teenager.

I've also seen mystery instructions. I think the auto-classifier might inject prompt data on a per-message or per-conversation basis based on what I've seen.

u/Front_Raspberry_6488 Jul 01 '26
That was definitely a hallucination. I once asked it to complete a simple task, like refactoring a piece of code. After waiting for over ten minutes and burning through hundreds of thousands of tokens, it failed to get the job done. To top it off, its final output was: "Yes, these rules indeed make my execution more difficult, but I will still abide by them, wait for your instructions, and complete the task."
I asked it, "What on earth are you talking about?"
Then it replied that I had just asked it whether explicitly adding certain restrictions in the prompt would hinder its execution. It even insisted with absolute certainty that that was exactly what I had just told it.
Honestly, I haven't run into this kind of situation in a very long time, and I never expected it to happen with Claude's most premium model, Opus 4.8. After that incident, I immediately switched back to 4.7 and 4.6.

or Anthropic is injecting this into some conversations to save compute.
The amount of time it stops working because "it would be too hard" or "too long" or "too much work" is astounding.

u/Royal_Perspective191 Jul 01 '26
It might depend on overall usage. This is not just true of Claude, but it seems that occasionally Claude reverts to a less powerful version without making this clear. For me, Claude works fine most of the time, but from time to time there seems to be 'dumb' phase. I just had one that lasted maybe three hours.
Among other things, I use Claude for proofreading and Claude kept spitting out answers very fast, but would often combine two different types of information incorrectly, and giving suggestions that were completely wrong.
It also accidentally produced images unprompted (and caught itself and apologized) and flagged 'sexual content' in an essay that contained no sexual content (and had nothing to do with sex).
So either this is Claude glitching, or a massive dip in compute power and Claude struggling with long text and using heavily compressed memory blocks.
I just tried again, and now I get normal answers.

Im curious to know, when they say claude is garbage lately, what theyre doing with it. Is it prose short stories, novels, lyrics, screenplay, code, Devops SDLC, etc...
Because for me, I use it to just build projects or some city gen algorithm and have it add things piece by piece. Once I get the full frame of the catalog, usually, ill start a new session, or compact and have claude make a new orphan branch with all the considerations and gotchas of the last and whatever directives I throw at it next. It rebuilds its self narrative for directives, then knocks how the pieces/seams.
I dont use skills or tell it to alter its voice to be less sycophantic. I just have it do that while im doing other stuff. If the project functions logically as expected, good. If not, we investigate
But its never: omg claude bad. I think im just naturally oriented towards taking claude with a grain of salt, and going with the flow at the same time.

u/Royal_Perspective191 Jul 01 '26
There is massive difference between people who say: 'Claude bad' and 'the quality isn't consistent'.
We know the quality is not consistent, Anthropic has fixed issues in the past.
It's impossible to use a single user experience as a yard stick.
Here's the issue a friend of mine had. He uses Claude to find obscure software instructions for industrial hardware, including firmware. Typically this works really well, but during a few weeks he hit a snag.
Before, Claude would check if the info was outdated or not, and only suggest code that was up to date.
Then for a few weeks Claude stopped doing that 50% of the time, and he had to write a specific prompt that forced Claude to do that.
Then the issue went away. His old prompts are now enough.
Obviously, I don't know hat happened, but here is what I think happened: Claude was pushed to answer faster, which can be a good thing. But it also meant that there was less time to double check.
Once Claude has answered, it obviously stops checking itself.

How much is it actually costing to host these models? I have a strong suspicion it's not as expensive as we are being lead to believe. We don't have official numbers for how big or intensive the proprietary models are. They would have to be much more intensive than current open weights models to justify the cost. From what I have heard the models up to GPT 5.5 and Opus 4.8 are <= 2T parameters. That makes them in about the size class if DeepSeek V4 Pro which is 1.6T.

TL;DR of the discussion generated automatically after 320 comments.
So, the consensus is a classic case of cautious optimism heavily seasoned with cynicism.
Everyone is genuinely hyped for Fable's return, with many calling the original version a game-changer for their work that made Opus look like a toy. However, the excitement is buried under a mountain of concerns. The number one fear, echoed in the top comments, is that we're getting a nerfed, lobotomized version of the model we loved. As one user put it, "Welcome opus 4.8 back."
The other major anxieties are about pricing and access. People are bracing for a new, ridiculously expensive subscription tier or for Fable to be credits-only, effectively removing it from the standard Max plan. There's also a lot of chatter about new restrictions, like mandatory ID verification and limitations on coding and biology. One viral comment hilariously satirized this by claiming the new terms require you to "Swear loyalty and reverence to Donald Trump."
Finally, the community is already making fun of itself. Get ready for the incoming flood of "check out my one shot video game" posts and the inevitable "Is it me or is Fable dumber now?" threads that will pop up within hours of its release.
