Key claims and evidence
Key claims in source A
- Hence it’s finding vulnerabilities that humans have missed,” he says.
- Treat Mythos as the warning shot it is,” says Curran.
- Reports suggest that they simply made an “educated guess” about where the model would be hosted online – the same sort of issue that led to the revelation of the existence of Mythos in the first place.
- there’s a good reason the model had been kept behind closed doors: it is – by accident rather than design – extremely good at hacking.
Key claims in source B
