Anthropic announced the release of Claude Haiku 4.5 , a new, smaller language model. Officials claim its performance in core tasks like code generation is now approaching that of its flagship model , Claude Sonnet 4, released five months ago. Haiku 4.5 is reportedly designed for high-concurrency and cost-sensitive applications, running at just one-third the cost of Sonnet 4 while maintaining comparable performance. The model boasts over twice the inference speed.
Haiku 4.5 is now available on multiple platforms, including GitHub Copilot and Amazon Bedrock, and supports enterprise-grade deployments. The new model inherits the Claude series' multi-turn conversation capabilities and contextual understanding advantages while also being optimized for low-latency and high-throughput scenarios. Industry experts believe that the release of Haiku 4.5 signals Anthropic's accelerated development of its multi-layered model matrix, strengthening its market competitiveness through differentiated performance and pricing strategies.
