    The maximum number of characters allowed for embedding in a single request varies by model:

    • Embedding-V1 model: up to 1000 characters
    • bge-large-zh model: up to 2000 characters
    • bge-large-en model: up to 2000 characters
    • tao-8k model: up to 28000 characters

    Note: These limits are model-specific and should be adhered to for optimal performance.

    modelName: "embedding-v1" | "bge_large_zh" | "bge_large_en" | "tao-8k" = "embedding-v1"

    Model name to use

    stripNewLines: boolean = true
