Claude Fable 5.2 and Mythos 5.2

I feel like I'm increasingly reading AI current events is more like learning about historical events. By the time information has entered my head, there is even newer information out there that already makes what my brain is only currently actively processing, obsolete.

Also, the frontier labs are probably always internally using a model more advanced than what has been publicly released.

Because they do months of testing. Also, if they have models that are really good at AI research, I’d not expect full versions to ever be released, precisely because of their love of money.

Inference on the research models they have is likely more expensive than the released ones.

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.

Welcome to Singularity.

Now imagine feeling like this, except not just about "AI events" but about everything around you.

I have to imagine if I worked for one of these companies on the frontier models it would be very difficult to leave for that reason. Thee pay is also pretty good.
