What pricing changes? As far as I can tell they've all been coming down for the past few months. Currently the cost is pennies per day with gpt3.5-turbo. Though I probably would be using one of the locally runnable models if I didn't have a terrible integrated GPU or Hetzner had more affordable GPU servers. Probably not going to share the source because someone would just spam obnoxiously with it and end up getting my accounts banned too.
