Anthropic reveals Claude Haiku 5.5, its cheapest and fastest small model yet

Anthropic has released Claude Haiku 5.5, its smallest and most affordable AI model yet. According to 9to5Mac, this is the third Claude 5.5 model upgrade over the last month, following Opus and Sonnet upgrades. Haiku 5.5 is designed for high-volume, cost-sensitive tasks such as classification, summarization, and extraction, including live support, voice agents, and in-app assistants.

The new model costs around 75% less to run than its predecessor, Haiku 4.5, as reported by Economic Times Tech and Decrypt. Specifically, Techmeme states that Haiku 5.5 is priced at $0.10/1M input and $0.50/1M output tokens for requests up to 100K tokens, and $0.50 and $2.50 above. This makes it suitable for tasks like summaries, live customer support, and repetitive workloads.

Haiku 5.5 arrives 15 days after Opus 5.5, according to Decrypt. Anthropic's Haiku model range has been upgraded from version 4.5 to version 5.5, marking a significant improvement in speed and cost-effectiveness. The company has also made improvements to the value of its model range, including halving the price of Claude Sonnet 5.5's cache reads.
