CLI Quickstart For Embeddings

Walk through the core vai embedding commands: model discovery, embedding generation, explainers, and similarity.

Prerequisites

A valid VOYAGE_API_KEY is set in the environment.

Under the hood

See the exact VAI command, the matching Voyage AI layer, and the MongoDB query shape behind the demo.

vai embed "What is MongoDB Atlas?"

This is the one-liner developers see first in the demo. VAI wraps the request, formats the response, and prints the vector without forcing you to write any client code.

What Is an Embedding?

Start from first principles: generate a Voyage embedding, inspect its shape, and compare full-size versus Matryoshka-reduced vectors.
