Method and limitations

Cache discounts apply only to the percentage of input tokens entered as cached. Batch discounts apply to the eligible percentage of token charges. Estimates exclude taxes, retries, tool calls, embeddings, image/audio tokens, reasoning-token billing and provider-specific rules unless represented in fixed costs. Verify current pricing and discount eligibility before budgeting.
