+ How should I estimate the total cost of Modal Sandboxes? Because Modal Sandboxes are billed based on active resources, you should estimate total cost differently than you would with other Sandbox providers who charge based on fixed reservations. For CPU, you can estimate by calculating: Sandbox duration × rate × average CPU cores used. For memory, you can estimate by calculating: Sandbox duration × rate × average GiB used. It's important to use the average resource consumption instead of the peak because Modal Sandboxes are charged based on the max(request, usage). For most Modal Sandboxes, the guidance is to not request any resources, defaulting to a small reservation of 0.125 cores and 128 MiB of memory. Modal Sandboxes are designed to burst above their reservation as needed. Since Sandboxes typically have bursty resource consumption, the difference between peak usage and average usage can be significant. Calculating the price of Modal Sandboxes by using peak resource consumption will usually significantly overestimate the total cost.
