About
Claude Haiku 4.5, released by Anthropic in October 2025, is the speed-optimized model in the Claude 4.5 family — designed for high-throughput production applications where response latency and inference cost are primary constraints. It gives developers access to Claude 4.5-generation quality in a format suitable for interactive applications and high-volume API usage where the larger models in the family would be unnecessarily expensive.
