API Key

# env variable
os.environ['GITHUB_API_KEY']

Sample Usage

from litellm import completion
import os

os.environ['GITHUB_API_KEY'] = ""
response = completion(
    model="github/llama3-8b-8192", 
    messages=[
       {"role": "user", "content": "hello from litellm"}
   ],
)
print(response)

Sample Usage - Streaming

from litellm import completion
import os

os.environ['GITHUB_API_KEY'] = ""
response = completion(
    model="github/llama3-8b-8192", 
    messages=[
       {"role": "user", "content": "hello from litellm"}
   ],
    stream=True
)

for chunk in response:
    print(chunk)

Usage with LiteLLM Proxy

1. Set Github Models on config.yaml

model_list:
  - model_name: github-llama3-8b-8192 # Model Alias to use for requests
    litellm_params:
      model: github/llama3-8b-8192
      api_key: "os.environ/GITHUB_API_KEY" # ensure you have `GITHUB_API_KEY` in your .env

2. Start Proxy

litellm --config config.yaml

3. Test it

Make request to litellm proxy

curl --location 'http://0.0.0.0:4000/chat/completions' \
--header 'Content-Type: application/json' \
--data ' {
      "model": "github-llama3-8b-8192",
      "messages": [
        {
          "role": "user",
          "content": "what llm are you"
        }
      ]
    }
'

import openai
client = openai.OpenAI(
    api_key="anything",
    base_url="http://0.0.0.0:4000"
)

response = client.chat.completions.create(model="github-llama3-8b-8192", messages = [
    {
        "role": "user",
        "content": "this is a test request, write a short poem"
    }
])

print(response)

from langchain.chat_models import ChatOpenAI
from langchain.prompts.chat import (
    ChatPromptTemplate,
    HumanMessagePromptTemplate,
    SystemMessagePromptTemplate,
)
from langchain.schema import HumanMessage, SystemMessage

chat = ChatOpenAI(
    openai_api_base="http://0.0.0.0:4000", # set openai_api_base to the LiteLLM Proxy
    model = "github-llama3-8b-8192",
    temperature=0.1
)

messages = [
    SystemMessage(
        content="You are a helpful assistant that im using to make a test request to."
    ),
    HumanMessage(
        content="test from litellm. tell me why it's amazing in 1 sentence"
    ),
]
response = chat(messages)

print(response)
