GPT-5.4-Pro launches with advanced debugging capabilities

OpenAI's GPT-5.4 model sparks technical discussion among staff including Thibault Sottiaux, Member of Technical Staff leading Codex, who references GPT-5.4-Pro variant and Fable naming, and Adam Goldberg, Team Lead of Financial Services in GTM, who states it maintains or improves intelligence levels. Systems engineer Yacine (kache), formerly at X and Stripe and now building a hardware startup and fast robot sim infrastructure, reposts that GPT-5.4 reads disassembled binaries to set breakpoints and detect bugs.

@thsottiaux You'd also need to breathlessly talk about it being too dangerous to release, and that AI needs a global "pause", prior to releasing it.

RT @PhiloGroves: GPT 5.4 is currently reading disassembled binaries directly to establish breakpoints and find bugs.

How long ago was this…
