1,000,000 context tokens · max output 128,000. Local token counts are estimates; use the provider’s usage counts for an invoice estimate.
Text-only estimate. Local token counts are approximate; use provider-reported usage for billing. Tool, image, audio and video charges are excluded.
No long-context premium within the 1M context window. Cache writes: 5-minute and 1-hour retention are separate input billing operations.
US-only inference adds 10% to token rates and is excluded from this global-endpoint estimate. Newer Claude tokenization differs from the local estimator; no fixed conversion factor is applied.
Billed output includes reasoning/thinking tokens that cannot be inferred from pasted final text; use API-reported output usage for accurate billing.
Batch: Batch cache read/write combinations are not estimated here; use uncached input or consult the official source.
