I’ve been doing decompilation with LLMs for 4 months, and 5.5 is so insanely good I now can finish Windows 95-98 games in just a week. And by finish I mean get byte-to-byte exact output from your decompiled code to retail with clear names, semantics and no “Ghidra smell”. With older Opus models you would have to manually guide them and inspect ASM yourself otherwise they will just burn through your tokens (which also used to cost more!)

And I have way more on my gh.
