Frequently asked questions
Which LLM is cheapest for my workload?
It depends on your mix of input and output tokens and how many requests you run per month. Enter your volumes and the comparison highlights the model with the lowest projected monthly cost, and shows how much each alternative costs versus that winner.
How is the monthly cost calculated?
Each model applies its own per-million input and output token rates to the shared token volumes you enter, multiplied by your monthly request count. Cached-input and batch pricing modifiers are applied when enabled.
Are the prices up to date?
Model prices are maintained from each provider’s published API pricing and dated in the calculator. Deprecated models are excluded from the comparison picker.
