I never hit Anthropic's safety filter when I'm doing something illegal, only when I'm not.
Honestly, unless what you are doing is frankly illegal, it usually is possible for you to get around most safeguards for coding things if you also know how to write code. Most problems have a separable completely innocuous core that Fable would gladly do. Then you can implement the problematic parts yourself. Particularly things like copyright issues, web scraping etc.
I hit the safety feature when I ask something I saw that blocked other biologists: "why did the chicken cross the road?"
Due to my standard cancer research work I'm blocked from Fable.
That said, with how execrable all the 5 models have been, I can't imagine I'm missing much. It's impossible to get an intelligible explanation in text out of the 5 models, and the mistakes are just comically bad on anything that's not code.
Cancelled my subscription, and can't imagine going back since OpenRouter gives me a consistent model that I can trust won't change underneath me.
