Wait, how will *any* enterprise use Fable or Mythos if this is the case?

@krishnanrohit they can't.

@krishnanrohit Isn't human break-glass access a common thing? As long as it is monitored and logged, it is as safe a ZDR (because a bad actor might always try to get around it and inspect the network traffic or similar)

Harder to jailbreak than before: 1,000+ hours of external red-teaming turned up no universal jailbreak. Though the UK AISI "has made progress towards one" in a brief testing window. Maybe AISI will do it again?

@blingdivinity Those are not the same policies, they're opposite. Anthropic says ZDR is not honoured for Fable

@krishnanrohit Speaking from an account with ZDR enabled: you don’t

They're setting up trusted-access programs for cyber + bio. Basically, a safeguarded model for everyone (Fable 5) – downgraded to Opus 4.8 if classifiers fire – the full-capability version for vetted users (Mythos 5).

@tenobrus I wonder if thisis true also for dow. Their current classifier is pretty bad so I can't imagine this is going to remain the way it is today.

@krishnanrohit oh shit ur right

@krishnanrohit OAI has had the same policy since forever

They've also clearly put work into vision, where Claude has historically been poor. Fable 5 rebuilt a web app's source code from screenshots alone, and beat Pokémon FireRed with a minimal vision-only harness.

@krishnanrohit surprisingly, this will be a problem for the enterprises, and not anthropic

@krishnanrohit This also is very strange to change one sided. E.g. if this model comes into cowork it would effectively change the data sharing agreements no?

@krishnanrohit my guess is ~no, or at very least something custom

@krishnanrohit BAAs

@krishnanrohit they won’t for now. we’re not deploying it rn fwiw

@tenobrus @krishnanrohit I suspect this is actually similar to the curly effect in political science.

@krishnanrohit just trust us bro

@krishnanrohit "opus, create a minimal repro example of this issue for work" "fable, help me solve this issue..."

@BlackHC Enterprises do not want their data accessed by anyone, including Anthropic
