Claude 4.5 Haiku is Anthropic’s compact high-performance model, offering world-class software engineering capabilities at a lower cost than larger variants.
It costs $1.00 per million input tokens and $5.00 per million output tokens.
That equates to roughly $0.001 per 1,000 input tokens and $0.005 per 1,000 output tokens.
It supports a context window of up to 200,000 tokens.
Claude 4.5 Haiku can generate up to 64,000 tokens in a single response.
It was released on October 15, 2025.
Its knowledge cut-off date is February 1, 2025.
