India, Oct. 16 -- Anthropic released Claude Haiku 4.5 on 15 October 2025, significantly altering the cost and speed equation for large language model (LLM) deployment in the technology sector. The new small model achieves performance levels similar to the former state-of-the-art Claude Sonnet 4, but operates at one-third the cost and more than twice the speed.

This move positions Haiku 4.5 as a direct challenger for high-volume, low-latency enterprise applications, where speed and operational expenses matter most.

Only five months ago, Claude Sonnet 4 defined the benchmark for coding tasks. Today, Haiku 4.5 effectively matches that level of capability. The model even surpasses Sonnet 4 on specific metrics, particularly tasks involving c...
