How much does the Claude API cost?
Start with the work unit you can measure: one conversation, document, article or agent run. Record both prompt and response length, then multiply by real monthly volume. Output often costs more than input, so a concise answer can matter more than a short prompt.
Price is only one constraint. Check context length, modalities, tool support, latency and output quality before choosing a production model. Test a small representative sample instead of relying on a single benchmark.
