I simply don't get how it could have run for quite a while and only cost $3. Z.ai offers some of the best model out there. Several dollars per million tokens, this sort of bot to generate code would burn millions in less than 30 minutes.

The flagship, glm-5, is $1/M input tokens. glm-4.7 is $0.60/M input tokens.

They have a coding plan

And the $3 plan also has significant latency compared with their higher tier plans.
