What is the usecase for Haiku?

A developer questioned the use case for Haiku, noting that it struggled with a simple math problem. The model provided an incorrect solution for the equation 10x - 15 - 2x - 8 = 3, calculating x = 3.25 instead of the correct x = 3. This led the developer to use Opus for generating questions, which still required significant refinement, highlighting Haiku's limitations for even basic tasks.

This report highlights Haiku's limitations in basic math, unlike more capable models such as Opus, which still required refinement for similar tasks.
