The short version
- Anthropic released Claude Haiku 5.5 on October 7.
- Input costs $0.10 per million tokens and output $0.50 per million for prompts under 100,000 tokens.
- The model has a 1 million-token context window.
What happened
Anthropic added a new small model to its Claude family. Haiku is the fast, cheap tier, and this release pairs low per-token prices with a context window large enough to hold whole codebases or long document sets.
Why it might matter
Cheap long-context models make it practical to run summarising and sorting jobs over large inputs, the kind of job this site runs four times a day.
What we don’t know yet
Pricing above 100,000 tokens per prompt was not in the sources swept.
