Claude Haiku 5.5 launches at a tenth of Haiku 4.5's price

Anthropic released Claude Haiku 5.5 at $0.10 / $0.50 per million tokens for prompts up to 100K tokens and $0.50 / $2.50 above, with a 1M-token context. Anthropic's launch table puts it ahead of GPT-6 Luna on every benchmark both were run on. Its tokenizer is the Claude 4.7+ one, which turns the same text into about 30% more tokens than Haiku 4.5's.

Every price re-checked against the providers — and retired models marked

All 44 models were checked against each provider's own pricing and deprecation pages. Twelve current models were added, thirteen retired ones are now labelled with the date they were shut down and what replaced them, and every cost estimate now accounts for tokenizer differences — Anthropic documents that Claude 4.7 and later produce about 30% more tokens for the same text.
