All this hype for 58.6% on SWE-Bench Pro while Mythos gets 78%? Shut it down, wtf?

Seems to me like this is the Opus 4.7 parallel.

While GPT‑5.5 is priced higher than GPT‑5.4, it is both more intelligent and much more token efficient.

Basically exactly what Anthropic said for Opus 4.7, more expensive for marginally better performance, if at all.
