The loss of trust in using US based model's is unlikely to come back though. Anthropic with it's hyped doomsday messaging, and the administration falling for it (at best), has eroded a lot of trust and has triggered an arms race of sorts.

Here's to OpenAI and a chinese firms bringing some much needed competition.

Amusing to see OpenAI being the "good guy" in the end

Maybe, for some projects, instead of generating code with it, it would be useful to generate a plan and the loop(tests/formal verification),because those take much less tokens than a full project, and than use the loop using the older models ?

I think that's the idea, I saw some outrage on reddit about Fable using Opus to do code writing, another comment said exactly my reaction, why do you want to pay double for tool calling when Opus is just fine for the task?

It won't even review a cyber security blog post I wrote. Absolutely worthless and pitiful guardrails.

I'm having it review a project Opus 4.8 created. No security review, just "look for general issues, performance problems, missing features, etc." It spawned about twenty background tasks. It's still going, but so far, one has completed, and four have failed with guardrail messages. Nothing special, just stuff like reviewing the API:

Fable 5's safeguards flagged this message (https://www.anthropic.com/legal/aup). They may flag safe, normal content as well. These measures let us bring you Mythos-level capabilities sooner, and we're working to refine them. Claude Code can't respond to this request with Fable 5.

Try rephrasing the request in a new session or change your model.

This is incredibly stupid, particularly because I didn't write the request in the first place. Fable wrote it when it spawned the background task. How am I supposed to rephrase it?

Fable probably told itself to do a security review, and then failed itself for trying to do a security review, and now it's telling me not to tell it to do a security review.

Anthropics marketing dept were a tad overzealous with how they positioned this model, now it's biting them back.

If this was just another model without the hype doom marketing, I don't think we'd be where we are.

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.

If Opus 5 is capable enough, it will have the same guardrails with blocks/downgrades as Fable.

So now we are supposed to cheer for Opus 5 to be just a mild improvement at best?

Can the harness to auto-rephrase? I imagine, doing so will burn through tokens though.

This makes me think they really are quite capacity constrained at the moment. I had assumed they were primarily limiting it to entice people to upgrade, but I feel like these limits are so low and so temporary (especially over July 4th weekend in the US) that people will barely get a chance to get "used to it" and then think: "man, I can't live without this, I'll pay for API pricing".

If it's API pricing, I'm going to ditch Claude Code and switch to a harness that can jump between GLM and Claude Code. Cheap pricing is why I use Claude Code. The minute they fumble that, I'm using Chinese models for 90% of the work.

Yeah. Their cheap subscriptions are the only reason to keep using them. If they ruin the plans there's nothing holding us back anymore.

Not super impressed, but I doubt my requests are getting routed to Opus -- it just doesn't seem to be as good at mathematics as it is at code (I found this to be the case last time it was released as well).
