Key takeaways · AI-distilled
v0 supports two shared-environment-variable mechanisms for private packages: NPM_tokenThe chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.Full definition → for simple auth against registry.npmjs.org, and NPM_RC for configuring custom or multiple registries.
NPM_RC supports scoped registries (e.g. an @acme GitHub Packages scope) and can reference other environment variables, letting teams point v0 at a private registry like JFrog Artifactory without hardcoding secrets.
Credentials can be marked sensitive in Vercel and scoped to Development and/or Preview; v0 never exposes them to the model or writes them to the sandboxAn isolated environment where AI-generated code or agent actions run without being able to touch anything real.Full definition → filesystem, and integration status is visible under Settings then Integrations.

context window — The maximum amount of text a model can consider at once — its working memory for the current conversation or task.

Why it matters
Removes a blocker for using AI app builders like v0 inside companies with private package registries, and keeps credentials out of the model context windowThe maximum amount of text a model can consider at once — its working memory for the current conversation or task.Full definition → and sandbox filesystem.
