Usage

use synaptic::nomic::{NomicConfig, NomicEmbeddings};
use synaptic::core::Embeddings;

let config = NomicConfig::new("your-api-key");
let embeddings = NomicEmbeddings::new(config);

let docs = embeddings.embed_documents(&["Long document text...", "Another document."]).await?;
let query_vec = embeddings.embed_query("search query").await?;

Models

Task Types

Nomic uses task-type specific encoding. embed_documents() uses search_document and embed_query() uses search_query automatically.
