I had to remind myself what Haiku is even for. Anthropic hasn't spent a lot of recent marketing on it.

When I need a light model, I reach for Sonnet. It is nearly free on the max plans, and quite fast. I don't see a place for Haiku in regular coding.

Haiku I guess is when you need summarization/categorization at scale.

Microsoft setting Haiku as the benchmark is a low bar.
