Anthropic Haiku 5.5 cuts AI run costs 75% while boosting OSWorld
Anthropic launched Claude Haiku 5.5 on Oct. 7, targeting high-volume enterprise workloads with lower costs and stronger performance. Anthropic says the model costs about 75% less to run than Haiku 4.5 on average. The company also reported a major improvement on OSWorld, where Haiku 5.5 scored 72.4%, versus 15.7% for its predecessor.
The pricing reduction is even larger for requests up to 100,000 tokens. Anthropic charges $0.10 per million input tokens and $0.50 per million output tokens, compared with $1 and $5 for Haiku 4.5. About 90% of Haiku 4.5 requests fell into that lower-cost category. Meanwhile, Haiku 5.5 adds adjustable effort settings for balancing cost and intelligence.
The launch strengthens Anthropic’s position in a rapidly intensifying AI pricing race. Reuters said Haiku 5.5 is the third Claude 5.5 model released within a month, as Anthropic prepares for a potential IPO.
Why it matters
