How?? I'm using sol Extra High 24/7 and it eats up about 1% per hour reliably, so it lasts about 4 days for me.
Sub-agents. I have 7 20x accounts and I burn them within 1-2 days if I go fully parallel. In some scenarios I use 50 sub-agents for a session which is literally hours of usage for a single 20x account. I'm at the point where I need to parallelize over multiple machines because I just don't have enough CPU and RAM.
These folks are probably using crazy plugins or crazy sub agent spams. They probably just run everything on max + fast mode which is ridiculous.
