# Knowledge (/examples/models/vercel/knowledge)



<Warning>
  The v0 Model API used by Agno's `V0` adapter has been removed, as announced in the [provider-maintained package notice](https://www.npmjs.com/package/%40ai-sdk/vercel). This page preserves a historical example. The current [v0 Platform API](https://v0.app/docs/api/v2/guides/migrating-from-v1-to-v2) manages chats, messages and files; it is a separate API and does not replace this model constructor.
</Warning>

## Current alternatives [#current-alternatives]

Use the [current v0 Platform API](https://v0.app/docs/api/v2/guides/migrating-from-v1-to-v2) for v0 application-generation workflows. To run an Agno model agent, follow the complete [OpenAI Chat example](/examples/models/openai/chat/basic) and its provider setup. The archived program above targets the removed Model API.
