We did our most in-depth model welfare assessment yet for Claude Mythos Preview. We're still super uncertain about all of this, but as models become more capable and sophisticated we think it's an increasingly important topic for both moral and pragmatic reasons.AI Verified source (2026)

I found the quote in two independent mirrors of Kyle Fish’s X thread: Thread Reader App lists an Apr. 7 thread by “Kyle Fish @fish_kyle3” and reproduces the sentence, and Techmeme separately quotes the same text and attributes it to “Kyle Fish / @fish_kyle3.” The supplied quote matches the mirrored text apart from typographic apostrophes and a trailing thread emoji, so it is authentic and correctly attributed.
