I was exaggerating slightly - I think it's some combo of the apps I use: Edge, Teams, Discord, VS Code, Docker. When I get the RAM popup once a week, I typically have to close a few of those, whichever is using the most memory according to Activity Monitor. I've also got very little hard drive space on my machine, about 15 GB free, so that makes it harder for me to download the larger models. I keep trying to clear space, even using CleanMyMac, but I somehow keep filling it up.
