Why would I need a batch cost calculator?

Most AI applications make calls to multiple models — for example, a cheap model for classification and an expensive one for generation. A batch calculator lets you estimate the combined monthly cost before committing to an architecture.

How do I estimate monthly request volumes?

Start with your daily active users and estimate calls per user per day. Multiply by 30 for monthly totals. Add overhead for retries, background jobs, and evaluation pipelines — typically 10-20% more than user-facing calls.

Can I compare self-hosted vs API costs?

This calculator covers hosted API pricing. For self-hosting, estimate GPU cost per token based on your hardware (typically $0.10-0.50 per hour per GPU) and throughput (tokens per second), then calculate cost per million tokens.
