Questions
Claude API pricing FAQ
How should I compare Claude API prices?
Use the same input and output token counts across Claude models, then account for any caching or batch behavior specific to your workload.
Why can two Claude workloads using the same model cost differently?
Token mix, prompt caching, batch eligibility, context length, and tool use can change the effective price even when the base model is the same.
