How is monthly cost calculated?

Cost = (input tokens × input price/M) + (output tokens × output price/M), then × calls per day × 30 days. Token counts are approximate — actual cost depends on tokenization specifics.

How big is an average prompt?

Heuristic: 1 token ≈ 0.75 words in English. A 500-word system prompt + 100-word user message ≈ 800 input tokens. Output varies hugely — short JSON ≈ 50 tokens, long-form ≈ 500–2,000.

Why is self-hosted Llama "estimated"?

Self-hosting has no per-token pricing — your cost is GPU time. We approximate $0.30/M tokens both directions based on a typical H100 deployment at common throughput. Real cost depends on hardware utilization.
