Haiku
TL;DR
The lightest and fastest model in the Claude family, optimised for instant, simple tasks like summarisation, categorisation, and straightforward extraction.
Definition
The lightest and fastest model in the Claude family, optimised for instant, simple tasks like summarisation, categorisation, and straightforward extraction. Haiku 4.5 rivals the reasoning capability of previous-generation Sonnet 4.0. It consumes the least rate limit — ideal for batch processing and mechanical tasks.
Exam Context
A trap claims Haiku is "too limited for professional use." It is not — it excels at speed-sensitive batch tasks and simple extraction at a fraction of the rate limit cost.
