# 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](https://morphllm.com/?utm_source=docs.trychroma.com).

  <Tab title="Python" icon="python">
    This embedding function relies on the `openai` python package, which you can install with `pip install openai`.

    ```python theme={null}
    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"])
    ```

  <Tab title="TypeScript" icon="js">
    ```typescript theme={null}
    // 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,
    });
    ```
