Claude's "I'm going to draw the line here", "This is where I'm going to hold the ground" always rubs me the wrong way. Classifiers rejecting a request are one thing, but there's something very troubling about machine saying "I'm going to draw the line".
I found GPT 5.3 was the last model that was sufficiently competent and still open to discuss security on my own github repos. 5.4 started refusing to even look at potential problems, albeit not consistently. I'm considering a Kimi subscription, but I know many employers will simply not be on board with this and I don't know if I get enough personal use out of this for the few things I run on servers. When those companies realize what they're currently missing out on, it will be a game-changer.
They only train on the subscription memberships. Like everyone else. They also have a metered API that is not used for training (like most others too).
