You only pay from what you save
60 / 40 split — no hidden margin

LexiCo takes 40% of the savings the STONE engine delivers on your token consumption. You keep 60%. You never pay more than provider cost with no savings - meaning LexiCo only earns when you save.

Calculate savings View account types

Here is the formula

provider_cost = tokens_input_sent × pIn + tokens_output × pOut
gross_savings = max(0, tokens_input_saved × pIn)
savings_to_customer = gross_savings × 0.60
savings_to_lexico = gross_savings × 0.40
customer_charge = provider_cost + savings_to_lexico

Example: you would have paid 0,86 EUR at the provider without STONE. With 80% savings it costs you 0,45 EUR at LexiCo - 0,41 EUR in pure savings.
