Claude Haiku
Also known as: Claude Haiku / Haiku / claude-haiku-4
Anthropic's lightweight, high-speed model series — ideal for low-latency, low-cost scenarios such as high-volume chatbots and document screening pipelines.
Overview
The fastest and cheapest model in the Claude family, frequently cited alongside Qwen3.5-9B and GPT-4o-mini as a baseline in SLM comparisons. See Qwen3.5-9B vs GPT-4o-mini vs Claude Haiku.
Best-fit tasks
Often matches Opus/Sonnet accuracy for simple NLP tasks like classification, summarisation, and keyword extraction, making it the first choice for cost optimisation.
