Anthropic Model Names

This is silly, but today I realized that all of the Claude models are based off of musical terms.

Haiku - Fastest model - 3 line short poem
Sonnet - Balanced Model - model - 14 line poem
Opus - Most intelligent model - Musical composition / Significant work of art (Magnum Opus)

In this vein, it seems Cursor is being a bit cheeky calling their model Composer 1.
