Class EmbeddingInput

java.lang.Object

dev.langchain4j.model.embedding.request.EmbeddingInput

@Experimental
public class EmbeddingInput
extends Object

A single input to embed: one or more ordered Content parts that are fused into one Embedding.

A plain text input is simply a single TextContent. Multimodal models can accept an interleaving of text and image/video/audio parts (e.g. Cohere Embed v4, Voyage multimodal) — the whole interleaved list produces a single vector.

An EmbeddingRequest carries a list of EmbeddingInputs (the batch dimension), each of which carries a list of Content parts (the interleaving dimension).

Since:

1.18.0

Method Details

contents

public List<Content> contents()

contentTypes

public Set<ContentType> contentTypes()

The set of ContentTypes present in this input. An EmbeddingModel validates these against its supported content types.

text

public String text()

The text of all TextContent parts of this input, used by text-only models. For a plain single-text input this is just its text; when there are multiple text parts, they are joined with a newline.
