222222Claude 4.6 and later models (except Claude Haiku 5.5) and [Claude Mythos Preview](https://anthropic.com/glasswing) include the full [1M token context window](https://platform.claude.com/docs/en/build-with-claude/context-windows) at standard pricing. (A 900k-token request is billed at the same per-token rate as a 9k-token request.) Prompt caching and batch processing discounts apply at standard rates across the full context window.

224Claude Haiku 5.5 is priced by prompt length: a prompt of over 100,000 tokens pays higher prices. [Model pricing](https://platform.claude.com/docs/en/about-claude/pricing#model-pricing) and [Batch processing](https://platform.claude.com/docs/en/about-claude/pricing#batch-processing) list both sets of prices.
224Claude Haiku 5.5 is priced by prompt length: a request whose prompt is over 100,000 tokens pays higher prices. A request's prompt length counts all of its input tokens, including cache reads and cache writes. Each request is priced on its own: a request over the threshold pays the higher prices even when part of its prompt is a cache hit, and earlier requests keep the prices they were billed at. [Model pricing](https://platform.claude.com/docs/en/about-claude/pricing#model-pricing) and [Batch processing](https://platform.claude.com/docs/en/about-claude/pricing#batch-processing) list both sets of prices.
