Just saw a lot of people saying they want to take advantage of Brother Sun, teach him a lesson. Checked it out, Brother Sun's platform gives 100,000 points upon registration, it's a trial amount. Based on the current gpt-5-mini usage records on the page: 100,000 points ≈ over 90,000 tokens Converted to API costs, that's roughly about 0.7 RMB. You probably can't even say 'Hi' Other valuable models also require payment to use.
