From the model card:

  Model                AECI   95% CI (global)
  Claude Opus 5.5    174.78   170.33-180.29
  Claude Mythos 5.2  177.12   172.42-182.94
  Internal model     178.78   173.75-185.18
Considering the IPO is planned in a week, I doubt they are holding much back.

According to their S-1:

In H1 2026, cost of revenue is $2.3B.

In the same period, R&D was $9.4B. That is primarily spent on compute.

This is not a company that is optimizing for OpEx. OpEx is barely relevant to their plans. The only thing relevant to their plans is achieving AGI/ASI first, everything else is peanuts.
