In the thread “Ask HN: What was the last task where only a frontier model could do it?”
Helped: High reasoning model for complex security scanning
Got in the way: Older models produced false positives and nit-picking
… Feed something like that to, say, Gemini Pro 3.1 and you'll get a bunch of false positives back, nit-picking, or variants of "this could be insecure if the code around it changes in unreasonable ways in the future". Feed the same thing into GPT 5.5 x-high and then tens of minutes later it'll find half a dozen unauthenticated remote code execution vulnerabilities, arbitrary file read/write vulnerabilities, or similar. Until it got nerfed, Mythos was similarly a huge step up for a lot of people working on code security.
