Anthropic releases Claude Haiku 5.5 with up to 90% lower token prices

Claude Haiku 5.5 jumps from 15.7 to 72.4 percent on the OSWorld computer-use benchmark versus its predecessor. Token prices drop by up to 90 percent. A new tokenizer uses more tokens per task, which offsets some of the savings.

Why it matters: A small, cheap model reaching this level on computer use makes agentic workflows far more affordable to run at scale. The tokenizer caveat means real-world savings will be smaller than headline prices suggest, so teams should re-measure cost per task. It continues the pricing pressure across vendors on small models.
