Anthropic has launched Claude Haiku 5.5, an upgraded version of its smallest and most affordable AI model. The new model is priced at $0.10 per million input tokens and $0.50 per million output tokens for requests up to 100,000 tokens, and $0.50 and $2.50 for larger requests. According to The New Stack, this represents a significant price drop compared to Haiku 4.5, which cost $1 and $5 per million input and output tokens.

The new model is designed for high-volume, cost-sensitive tasks such as summaries, database queries, and classification requests. According to 9to5Mac, Haiku 5.5 is also Anthropic's fastest model to date, making it suitable for speed-sensitive tasks like live customer support. Anthropic claims that Haiku 5.5 "costs around 75% less to run" than the previous model version.

This is the third Claude 5.5 model upgrade in the last month, following Opus and Sonnet upgrades. According to 9to5Mac, Anthropic is also making improvements to the value of its model range, including halving the price of Claude Sonnet 5.5's cache reads.
