Vision Understanding

Bailian CLI command reference for vision understanding — image, document, and long video parsing with multilingual OCR.

A single command invokes Bailian's vision understanding capabilities from the terminal — parsing images, documents, and long videos.
Append --help to any command for full parameter details, e.g. bl vision describe --help. Every parameter that accepts a file URL also accepts a local path — the CLI auto-uploads it to temporary storage (valid for 48 hours), so you never need to host files as URLs yourself.
