The rates above are per unit. Your bill is those rates times how hard your code leans on AWS Lambda, plus everything around it. PrePrice scans your project, finds where you call AWS Lambda, and computes your real cost per user and what to charge.
Find your real cost — freeAWS Lambda is billed per metered unit of usage. See the table above for each dimension and its rate, and the official pricing page for plan minimums and included allowances.
The per-unit rate is only one of the four numbers that set your bill. The others are how much your app uses AWS Lambda, how often, and across how many users. Long prompts, retries, multi-step agents, and uncached repeated context all multiply the rate. PrePrice models that usage from your code so the number is real, not a guess.
