Transparent USD usage

Prism bills AI usage in real dollars based on the models and services used for your request. Before materially expensive operations, Prism shows an estimated cost. After completion, you see the final charge.

Illustrative pricing example
If the AI services used for a Pro request cost Prism $0.10, the usage charge is $0.20. If those same services cost Prism $0.10 on Free / PAYG, the usage charge is $0.25.
This is an illustration, not a claim that $0.10 is a typical provider cost.
