Anthropic launches Claude Haiku 5.5 with effort controls, priced at $0.10/$0.50 per million tokens
Anthropic released Claude Haiku 5.5, its cheapest, fastest, and most capable small model, designed for high-volume, cost-sensitive tasks like summaries and classification. It is the first Haiku model with effort controls. Pricing is $0.10 per million input tokens and $0.50 per million output tokens for requests up to 100K tokens, rising to $0.50 and $2.50 above that threshold, matching GPT-6 Luna's price but with a less generous tokenizer.

As previously promised , here's Anthropic's new fast, low cost model: Introducing Claude Haiku 5.5 . The previous Haiku, 4.5, was very much showing its age. It came out almost a year ago , and was priced at $1/million input and $5/million output - relatively expensive even back then, and a full 10x the price of OpenAI's GPT-6 Luna , released last month. The new Haiku exactly matches the price of GPT-6 Luna - $0.10/$0.50 - up to 100,000 tokens. Beyond 100,000 tokens the price increases 5x to $0.50/$2.50. Luna itself has a price increase at 272,000 tokens but only to $0.20/$0.75. Haiku 5.5 also uses a new, less generous tokenizer. My Claude Token Counter tool shows that the same long prompt uses around 1.25x as many tokens with Haiku 5.5 compared to Haiku 4.5, so there's a hidden price increase there. If your workloads fit in 100,000 tokens, Haiku is the same price as Luna and reports higher benchmark scores. Above 100,000 tokens, Luna looks like a much better deal. The most recent relea
