The strangest part is that it won't just reject ML research, which I can understand, it will sabotage it silently by using a worse model without revealing it is doing so.

It's just an insane level of deception and trust destruction for a company that at most is like 1 year ahead of its competition.

Edit; to be clear they tell you when they degrade it for cybersecurity and bio

The thing that I keep thinking about is the accounting / charging when it downgrades automatically.

Do they adjust the price of the api request so that only the tokens that were utilized by fable get charged at that price and the remaining tokens that the cheaper / nerfed (fable) model utilizes get charged at that price?

If the answer is no, could that be construed as fraud?

Can you imagine if AMD or Intel throttled your cpu if it detected you were working on "cybersecurity" or if you were designing a cpu?

Hey guys,

check out this technique https://github.com/0xSufi/fable-jailbreak/

It works with security audits and other workflows that are currently blocked.

Yeah people are saying they don't tell you and yet when I got the pop-up on the app notifying me about Fable's release, there was a switch to just automatically downgrade you or whether to just stop when it hits safeguards. The toggle was defaulted to the former, which isn't great, but to say they'll just sabotage you silently is kind of a bad faith comment.

I've seen this claim a few times, but when I triggered the guardrails in Claude Code, it clearly notified me that it had switched to a different model ("something something for security purposes...").

Are you using Fable in Claude Code or in the browser?

Making it look like you have something worth protecting is better for share prices than making something worth protecting.

I’m a noob about laws but isn’t this abusing its dominant market position and violates some antitrust law?

One year ahead of it's competition in what exactly? Vibe coding?

From Opus 4.7 onwards each following model is becoming less useful as an assistant and turning you as the assistant.

But I guess that's normal when it's trained to pass benchmarks end to end.

In fact it has become extremely good at pushing against feedback with extremely convincing and intelligent takes, even when it's completely wrong.

I have extensively tested it against Opus 4.8, gpt 5.5 and there's still many coding tasks gpt 5 is better. But vibe coding?

Sure, it's definitely slightly ahead, even compared to gpt 5.5 pro (through api, not pro plan).

By saying they are 1 year ahead of their competition, it shows you don't know much about the pace LLM's and OpenAI's models.

It's the dumbest thing ever, I sometimes edit code for custom AI related tooling I've built, so I run the risk of getting a worse model, and being billed for it? I'll stick to Opus, but at this point I'm about to just invest in fully local inference instead.
