# cohere call
response = embedding(
    model="embed-english-v3.0", 
    input=["good morning from litellm", "this is another item"], 
)

Setting - Input Type for v3 models

v3 Models have a required parameter: input_type, it can be one of the following four values:

• input_type="search_document": (default) Use this for texts (documents) you want to store in your vector database
• input_type="search_query": Use this for search queries to find the most relevant documents in your vector database
• input_type="classification": Use this if you use the embeddings as an input for a classification system
• input_type="clustering": Use this if you use the embeddings for text clustering
