119119**Example:** With a 2,000,000 ITPM limit and an 80% cache hit rate, you could effectively process 10,000,000 total input tokens per minute (2M uncached + 8M cached), because cached tokens don't count toward your rate limit.

122 Claude Haiku 3.5 (marked with † in the following rate limit tables) also counts `cache_read_input_tokens` toward ITPM rate limits.
122 Claude Haiku 3.5 (marked with footnote 4 in the following rate limit tables) also counts `cache_read_input_tokens` toward ITPM rate limits.

124 For all models without the † marker, cached input tokens do not count toward rate limits and are billed at a reduced rate (10% of base input token price). This means you can achieve significantly higher effective throughput by using [prompt caching](https://platform.claude.com/docs/en/build-with-claude/prompt-caching).
124 For all other models, cached input tokens do not count toward rate limits and are billed at the [cache read rate](https://platform.claude.com/docs/en/build-with-claude/prompt-caching#pricing), a fraction of the base input price. This means you can achieve significantly higher effective throughput by using [prompt caching](https://platform.claude.com/docs/en/build-with-claude/prompt-caching).

127127To make the most of your rate limits, cache repeated content such as system instructions and prompts, large context documents, tool definitions, and conversation history; see [prompt caching](https://platform.claude.com/docs/en/build-with-claude/prompt-caching) for guidance. With effective caching, you can substantially increase your actual throughput without raising your rate limits. Monitor your cache hit rate on the [Usage page](https://platform.claude.com/usage) to tune your caching strategy.
