Why ask me? Anyway, Mythos is not 10T. Anthropic confirmed the training run was under 10^26 flops. You can't train 10T to chincilla and stay under 10^26.

Anthropic also confirmed they will not release Mythos, only a "Mythos-class" model, whatever that means.

I don't think Anthropic have said anything of the sort.

Microsoft published it as 6.1*10^27 FLOPs[1]

Elon has claimed the are also training a 10T model because "Some catching up to do"[2]

I must have confused mythos with opus 4.7. One of their recent model cards confirmed that training flops was under the EO reporting requirement of 10^26 flops.
