* Example workload — chatbot, 100k requests/mo, 2,000 input / 300 output tokens per request, 70% of input cached. Computed by the same engine as the calculator. Batch: the −50% is Anthropic's verified Batch API discount; the ≈ $/mo column is computed without it.
Cached input is billed at 10% of the input rate across all Claude models we track — a major lever for chatbots and agents where most of the prompt repeats. The calculator models this with your cache share.
The Batch API runs asynchronous jobs at a verified −50% on both input and output across all models we track — flip the Batch toggle in the calculator to model it.
Claude Fable 5, Claude Opus 4.8 and Claude Sonnet 4.6 run a verified 1M-token context window; Claude Haiku 4.5 is 200k tokens.
