When to Use What

openai

Good default for structured generation and preset work.

codex

Useful if you want to experiment with a coding-optimized model anyway, but it is not the default recommendation for music generation.

anthropic

Kept for compatibility and alternative model behavior.

claude-cli

Useful when you want local Claude CLI auth without API keys in this project.

Chunking

For large style bundles, especially album-level bundles, use:

--sections 4 --chunk-size 2

This keeps prompt size and response latency under control.

Chunked generation keeps the selected style profile and tonal continuity lock active across chunks, so later chunks still receive role-presence and arrangement constraints.
