Yes: > After July 7, 2026, Claude Fable 5 is no longer included in your plan’s weekly usage limits. You can keep using Claude Fable 5 through usage credits, which let you pay for usage beyond what your plan includes. Learn more about using usage credits. I'm not sure what this means in the long run. Either Fable 5 might become part of the subscription again once stronger models become available or Anthropic's compute…

There will be an Opus 5 though.

I still don't understand the difference between the fable models and opus I mean why fable wasn't opus 5 and instead is a new name?

> OpenAI would kill to get that. I have news for you, from 5 days ago. https://news.ycombinator.com/item?id=48690101 "U.S. government will decide who gets to use GPT-5.6"

"W have to go through a regulatory approval process like everyone else" is so much less sexy than "Our model was so powerful that it got banned by the government after a few hours and now all our competitors have to go through a regulatory process invented because of us"

There's nothing sexy about it. From the get go they were accused of FUD drama and that it backfired as predicted. Now what I see in reality is that Anthropic mostly reaped more resentment from their poor marketing attempt. And their model is basically useless or unreliable from being lobotomized by guardrails.

Subscription folks barely have access to the model. Some report a single prompt before hitting weekly limit. And that's when it works instead of downgrading.

If that is a first movers play, it's a disastrous one.

How sexy do you think this guy finds Anthropic now?

> Today I told Sonnet (!) to use a browser MCP to enter a username and password for the project it is working on, it told me that it can't do that because it violates its security protocol.

> This worked fine before. I love Claude, I have stuck with it even through people saying Codex is better but this is definitely getting to be the last straw.

Meanwhile I can tell GLM 5.2 to decompile and crack anything I want with tools like IDA MCP and packet sniffing and it just works. Let alone code.

I'm really disappointed with Anthropic that they wont even mention if they will release a fable-like model with the subscription plans. If Opus 4.8 is the best model they will release on the subscriptions I may be too tall for the ride...which is sad, they have been my favorite of the labs until this. @AnyoneAtAnthropic, all we want are assurance we will still get SOTA models that are continuously improving, not regr…

I believe this is just their strategy to migrate away from these “almost all you can eat” subscription plans. Rather than reducing / removing Opus or Sonnet from the plans, they’ll just keep the new model Fable out (which may as well have been called Opus 5), and slowly everyone starts getting used to the new normal that you indeed will be having to pay API prices to get access to these models.

I think this is as good as time as any to bring up that fable/mythos weights are one mistake (malicious or not) away from being leaked to adverseries or available in a random torrent. Imagine this, fable weights are likely distributed to hundreds of datacenters with likely thousands of people directly or indirectly having partial or full access. I just don't quite buy that a 'world ending' fable/mythos model would be…

I don't think Anthropic is claiming it's world ending? Just that it has offensive cybersecurity abilities which can be dangerous

What about quality? Being cheaper and faster, while great and all, is less valuable than quality to me.

All the code an LLM produces is of questionable quality, so I'm not sure why you'd prioritize quality over speed. Speed is their only value add.

Have you compared models across providers? The quality, for the same task, varies tremendously. If you don't prioritize quality you're wasting your own time when you inevitably have to re-do the code...

What about all the benchmarks that show improvements in each generation?

Many of the improvements are the result of agentic loops and an emphasis on autonomy. Some of us don’t like that because the models go rogue and ignore design patterns, architecture, coding guidelines or other things that are important. My friends and colleagues that like the agentic autonomy don’t care about the code, they feel like if it works it works and if an AI system is the only intelligence able to understand…

the more agentic focused the better though?

sonnet 5 is very noticeably a much better model than any opus that ive touched

it actually does the things i want it to, and uses tools and triggers skills appropriately, vs trying to make stuff up

i believe it's more complicated than that. i know that nvidia offers TEE for their overpriced offerings. i would assume they make use of that so the weights are encrypted.

this doesn't mean it cannot leak but it would be a major undertaking.

this is why anthropic isn't that worried about having Elon service their models. the workflow would be something like handshaking with the nvidia TEE, provisioning it with your keys and then uploading encrypted weights. there is probably also a timer in there so you can't continue operating the nvidia box with the stolen weights without a heartbeat signal.

Is the model structure going to be easy to reverse engineer just from the weights? Also, I'm going to guess it's an MoE and thus it's possible there's no single machine that hosts all of Fabel / Mythos.
