PML (Prompt Markup Language) is the file format Infere uses to store prompts and evaluators in Git. YAML frontmatter declares the model, temperature, max tokens, and variables; the body holds the prompt itself. PML files deploy to the edge on push and are versioned like any other code.
Why it matters
Storing prompts as structured files makes them diffable, reviewable, and deployable - the difference between prompt engineering and prompt operations.
How it works
PML files use YAML frontmatter for model configuration and variables, and the body for the prompt itself. They are stored in Git, versioned, and deployed to the edge on push.
