Anthropic launches third Claude 5.5 model, expanding AI lineup before planned IPO
On Wednesday, Anthropic launched Claude Haiku 5.5, described as its "fastest and most efficient model," marking the third Claude 5.5 upgrade in the past month.
Anthropic reports the model "costs around 75% less to run" than Haiku 4.5, with pricing starting at $0.10 and $0.50 per million tokens for requests under 100,000 tokens.
Featuring new effort controls, Haiku 5.5 scored 72.4% on OSWorld 2.1 benchmarks and includes updated cybersecurity safeguards for high-risk requests.
Alongside this launch, Anthropic introduced monthly API credits for Team and Max subscribers and cut Sonnet 5.5's cache-read price by half to $0.10 per million tokens.
Expanding its artificial intelligence lineup ahead of a planned IPO, the model is available on Amazon Web Services, Google Cloud, and Microsoft Azure, complementing Opus 5.5 and Sonnet 5.5.
