• guarantees consistent output, text responses will always be available at ['choices'][0]['message']['content']

usage

Read the docs - https://litellm.readthedocs.io/en/latest/

quick start

pip install litellm

from litellm import completion

## set ENV variables

messages = [{ "content": "Hello, how are you?","role": "user"}]

# openai call
response = completion(model="gpt-3.5-turbo", messages=messages)

Streaming Queries

liteLLM supports streaming the model response back, pass stream=True to get a streaming iterator in response.

for chunk in response:
    print(chunk['choices'][0]['delta'])
