Morph

Chroma provides a convenient wrapper around Morph’s embedding API. This embedding function runs remotely on Morph’s servers and requires an API key. You can get an API key by signing up for an account at Morph.

Python
TypeScript

This embedding function relies on the openai python package, which you can install with pip install openai.

import chromadb.utils.embedding_functions as embedding_functions
morph_ef = embedding_functions.MorphEmbeddingFunction(
    api_key="YOUR_API_KEY",  # or set MORPH_API_KEY environment variable
    model_name="morph-embedding-v2"
)
morph_ef(input=["def calculate_sum(a, b):\n    return a + b", "class User:\n    def __init__(self, name):\n        self.name = name"])

// npm install @chroma-core/morph

import { MorphEmbeddingFunction } from "@chroma-core/morph";

const embedder = new MorphEmbeddingFunction({
    api_key: "apiKey", // or set MORPH_API_KEY environment variable
    model_name: "morph-embedding-v2",
});

// use directly
const embeddings = embedder.generate([
    "function calculate(a, b) { return a + b; }",
    "class User { constructor(name) { this.name = name; } }",
]);

// pass documents to the .add and .query methods
const collection = await client.createCollection({
    name: "name",
    embeddingFunction: embedder,
});
const collectionGet = await client.getCollection({
    name: "name",
    embeddingFunction: embedder,
});
