> When Claude Fable 5 declines a request, the Messages API returns stop_reason: "refusal" as a successful HTTP 200 response, not an error This is precisely what comes to mind when I think “successful”.

Is refusal something that can happen mid-stream, after status and headers have been received? I haven't looked at the API

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 ). Th…

yeah I'm also getting this for standard dev work, anything with kubernetes etc

completely nerfs the model because you can't let it do stuff over a few hours unattended because 90% it's going to switch to opus in first 10 minutes anyway

so seems best thing now is to have it write plans and then default to using opus for work anyway?

It's time for gpt 5.6 to come out too now.

That’s also going to be limited most likely. I don’t like governments deciding who can have the best products. I can’t shake the feeling there is money changing hands for getting on the access list as well with this administration.

Look, even if in this one instance Trump isn’t simply asking get his beak wet, that is the less believable scenario.

When “not cartoonishly corrupt” becomes hard to believe due to firmly established character and endless precedent, then it almost doesn’t matter if everything is on the level in this one matter.

The trust has been lost, undermining the ability to govern.

The fact that he’s still in power with firm support from everyone else that matters is all you need to know about how rotten to the core things are in your country.

America is no longer the greatest, or the best.

Except at grift…

I am only a casual Clause (Pro) user and I am confused by the messaging, maybe I'm missing something obvious. > Until July 7, you can use up to 50% of your plan's weekly usage limit on Fable 5. Does this mean that being able to use Fable on my subscription is a time-limited promotion? I have a subscription, why can't I just... use the model? Is it the case that going forward a subscription will only give you access t…

That didn't take long... Dynamic workflow "Multi-lens review of docs/membership-and-friends-model.md with adversarial verification" completed · 25m 59s You've reached your Fable 5 limit You've used your included Fable 5 usage for this week. Continuing on Fable 5 uses usage credits

Wow, practically totally useless.

> Fable wrote it when it spawned the background task. How am I supposed to rephrase it? Can the harness to auto-rephrase? I imagine, doing so will burn through tokens though.

Maybe set up Codex to rephrase stuff and remote control the Claude Code terminal?

What a surprisingly beneficial consequence for Anthropic.

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.

OTOH: “our product is so good it was banned for being too good” is the best advertising possible. OpenAI would kill to get that. I’m not falling over myself to test out Sonnet 5, but I am very interested in Fable.

I have news for you, from 5 days ago.

Not exactly. Every time I ask something using Fable, it switches to Opus. The subjects (and I tried many) seem to be irrelevant. Basically, I can't use Fable.

Check your CLAUDE.md, etc. for any of the banned topics or anything adjacent. Also check your recent Git commit history, if you're running the agent in a repository, as well. The classifier trips on anything anywhere in context, so those could be sources of rejections.

If the future of SOTA is handicaped models, then what's the point?

Writing code is already okay for current open models like GLM, QWEN.

I only need SOTA models for slop reviews, clean-ups and helping me with things I am not good at.

I have been extremelly happy with the results of cheaper models recently.

Composer 2.5 is a beast, fast and cheap. The upcoming Grok will probably be even better, since cursor helped trainning it.

Anthropic will lose market share quickly if they can't do better than this fable shit show...
