Introducing Claude Haiku 5.5
Anthropic launched Claude Haiku 5.5, matching GPT-6 Luna at $0.10 input and $0.50 output per million tokens.
Anthropic released Claude Haiku 5.5, a fast, low-cost successor to Haiku 4.5, which launched nearly a year earlier at $1 per million input tokens and $5 per million output tokens. Up to 100,000 tokens, Haiku 5.5 matches OpenAI GPT-6 Luna at $0.10 input and $0.50 output per million tokens. Beyond that threshold Haiku pricing rises fivefold to $0.50/$2.50, while Luna only steps up at 272,000 tokens to $0.20/$0.75. Haiku 5.5 also uses a new, less generous tokenizer.
- Haiku 4.5 cost $1/$5 per million tokens and is nearly a year old.
- Haiku 5.5 matches GPT-6 Luna at $0.10/$0.50 up to 100,000 tokens.
- Above 100,000 tokens Haiku pricing rises fivefold to $0.50/$2.50.
- A new, less generous tokenizer counts the same prompt as more tokens.
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…
