Claude Haiku 5.5

Anthropic's claude-haiku-5-5, 1M tokens of context. Every number on this page was read off Anthropic's own pricing page — never estimated, never recalled from memory.

How Anthropic describes it

“Claude Haiku 5.5 is built for high-volume, latency-sensitive work such as classification, routing, extraction, and subagent tasks.”

From Anthropic's documentation

• Long prompts: “Claude 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.” (official pricing page, read October 11, 2026)
• Versus its predecessor: “It uses the same newer tokenizer as Claude 4.7 and later models, so the same text counts as approximately 30% more tokens than on Claude Haiku 4.5.” (model page, read October 11, 2026)
• Batch API: “On the Message Batches API , Claude Haiku 5.5 supports up to 300k output tokens with the output-300k-2026-03-24 beta header.” (model page, read October 11, 2026)

Pricing

Long-prompt tiers

Pricing changes above a prompt-size threshold. If your average request is near the boundary, the effective rate is not the headline rate.

At the calculator's starting volume, 1M input tokens and 200K output tokens with no cache hits, Claude Haiku 5.5 costs $0.20: $0.10 for input and $0.10 for output, at the prices above. Same formula as the calculator; change the volume there.

Where this price sits

$0.10 per 1M input tokens (for prompts up to 100K tokens) is the 3rd cheapest input price of the 68 current models with a verified price on this site, and the 1st of Anthropic's 15. Output costs 5.0× the input price.
