Call all LLM APIs using the OpenAI format [Anthropic, Huggingface, Cohere, TogetherAI, Azure, OpenAI, etc.]
📣1-click deploy your own LLM proxy server. Grab time, if you're interested!
LiteLLM 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
By default we provide a free $10 key to try all providers supported on LiteLLM.
pip install litellm
from litellm import completion

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