Where this lands

Cheap enough to ship. At this volume inference cost is not your bottleneck.

Estimated from public list prices, model inference only. Actual pricing follows each provider. Excludes hosting, database, development and operations.

Want someone to bring this number down?

I have taken AI cost from ‘too expensive to ship’ to ‘a few dollars a month’ using model tiering, prompt caching and a fixed-answer library. Tell me your case.
