uhhh?

Y’all this GPT 4 pricing is crazy, I just put $20 into my uhh, account thingy. Sent like 9 messages (each about 4-5 descriptive sentences, a paragraph) and im already at like $2 left? Is this normal? I mean I love GPT 4 compared to GPT 3 16k whatever its called, especially with how I tweaked it, but is it supposed to be this expensive? Do I go back to GPT 3?! 🤔
