I didn't mean that - I meant that when, for example, Anthropic started, then later finished their Mythos/Fable pre-training run that people at OpenAI and elsewhere would have heard about it, probably knew some details such as the size of the model etc - people from these companies go out and socialize with each other, attend parties, share houses ...

So, it's not coincidence when they respond to each others models with something roughly equivalent - because they know what each other are working on.
