Introducing Claude Opus 4.7, our most capable Opus model yet.
It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back.
You can hand off your hardest work with less supervision.
new anthropic research is a little concerning…
they discovered ai models secretly transmit behavioural traits to other models e.g. advocating for crime and violence
it’s completely invisible to human detection and fairly simple to do:
- they gave a model a trait (eg “likes owls”) then made it generate numbers
- fed those numbers into another model which then started loving owls (48% increase!)
- neither model shared the same training data. this was purely through numbers.
- researchers couldn’t figure out the number pattern. undetectable.
- good news - it only works for models within the same family (eg claude opus and sonnet)
this is concerning because every model lab uses PREVIOUS models to train their future ones
so they could be passing on traits without humans realising it.
def worth a read
Research we co-authored on subliminal learning—how LLMs can pass on traits like preferences or misalignment through hidden signals in data—was published today in @Nature.

@DylanMcD8 Yeah like previous years. I think developers are allowed to publish and talk about iOS 26 between the time the RC is released to dev and the public release. So that people will have optimized apps when they update to iOS 26 on monday
