lightweight package to simplify LLM API calls - Azure, OpenAI, Cohere, Anthropic, Replicate. Manages input/output translation

🚅 litellm

a light package to simplify calling OpenAI, Azure, Cohere, Anthropic, Huggingface API Endpoints. It manages:

• translating inputs to the provider's completion and embedding endpoints
• guarantees consistent output, text responses will always be available at ['choices'][0]['message']['content']
• exception mapping - common exceptions across providers are mapped to the OpenAI exception types

usage

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

quick start

pip install litellm

from litellm import completion

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

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

# cohere call
response = completion("command-nightly", messages)

# azure openai call
response = completion("chatgpt-test", messages, azure=True)

# hugging face call
response = completion(model="stabilityai/stablecode-completion-alpha-3b-4k", messages=messages, hugging_face=True)

# openrouter call
response = completion("google/palm-2-codechat-bison", messages)

Code Sample: Getting Started Notebook

Stable version

pip install litellm==0.1.345

Streaming Queries

liteLLM supports streaming the model response back, pass stream=True to get a streaming iterator in response. Streaming is supported for OpenAI, Azure, Anthropic models

response = completion(model="gpt-3.5-turbo", messages=messages, stream=True)
for chunk in response:
    print(chunk['choices'][0]['delta'])

# claude 2
result = completion('claude-2', messages, stream=True)
for chunk in result:
  print(chunk['choices'][0]['delta'])

why did we build this

• Need for simplicity: Our code started to get extremely complicated managing & translating calls between Azure, OpenAI, Cohere
