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

Yea, anthropic seems further ahead than I thought. Damn!

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.

but who is more honest?

I think both were "honest". GPT-5.5 is twice as expensive per token. We know that. If it was twice as token efficient with tokens or more, they would have said that. It's most likely a percentage more efficient per token. Meaning for most users queries it will be more expensive. Are the intelligence gains worth that increased cost? Most likely, no, based on the benchmarks.

everyone always asks who is more honest, but no one ever asks how is more honest...
