Setup WatsonX

To set up WatsonX, follow these steps:
  1. Access WatsonX:
    • Sign up for WatsonX.ai.
    • Create an API_KEY and PROJECT_ID.
  2. Validate WatsonX API Access:
    • Verify access using the following commands:
Tip: Verify access to watsonX APIs before installing LiteLLM. Get Session Token: 
curl -L "https://iam.cloud.ibm.com/identity/token?=null"
-H "Content-Type: application/x-www-form-urlencoded"
-d "grant_type=urn%3Aibm%3Aparams%3Aoauth%3Agrant-type%3Aapikey"
-d "apikey=<API_KEY>"
Get list of LLMs: 
curl -L "https://us-south.ml.cloud.ibm.com/ml/v1/foundation_model_specs?version=2024-09-16&project_id=1eeb4112-5f6e-4a81-9b61-8eac7f9653b4&filters=function_text_generation%2C%21lifecycle_withdrawn%3Aand&limit=200"
-H "Authorization: Bearer <SESSION TOKEN>"
Ask the LLM a question: 
curl -L "https://us-south.ml.cloud.ibm.com/ml/v1/text/generation?version=2023-05-02"
-H "Content-Type: application/json"
-H "Accept: application/json"
-H "Authorization: Bearer <SESSION TOKEN>" \
-d "{
  \"model_id\": \"google/flan-t5-xxl\",
  \"input\": \"What is the capital of Arkansas?:\",
  \"parameters\": {
    \"max_new_tokens\": 100,
    \"time_limit\": 1000
  },
  \"project_id\": \"<PROJECT_ID>"}"
With access to watsonX API’s validated you can install the python library from here.

​
Run LiteLLM as a Docker Container

To connect LiteLLM with an WatsonX models, configure your litellm_config.yaml. Example 1: 
model_list:
    - model_name: llama-3-8b
    litellm_params:
    # all params accepted by litellm.completion()
    model: watsonx/meta-llama/llama-3-8b-instruct
    api_key: "os.environ/WATSONX_API_KEY"
    project_id: "os.environ/WX_PROJECT_ID"
Example 2: 
- model_name: "llama_3_2_90"
    litellm_params:
    model: watsonx/meta-llama/llama-3-2-90b-vision-instruct
    api_key: os.environ["WATSONX_APIKEY"] = "" # IBM cloud API key
    max_new_tokens: 4000
Before starting the container, ensure you have correctly set the following environment variables:
  • WATSONX_API_KEY
  • WATSONX_URL
  • WX_PROJECT_ID
Run the container using: 
docker run -v $(pwd)/litellm_config.yaml:/app/config.yaml \
-e WATSONX_API_KEY="your_watsonx_api_key" -e WATSONX_URL="your_watsonx_url" -e WX_PROJECT_ID="your_watsonx_project_id" \
-p 4000:4000 ghcr.io/berriai/litellm:main-latest --config /app/config.yaml --detailed_debug

Initiate Chat

To communicate with LiteLLM, configure the models in phi1 and phi2 and initiate a chat session. 
from autogen import AssistantAgent

phi1 = {
    "config_list": [
        {
            "model": "llama-3-8b",
            "base_url": "http://localhost:4000", #use http://0.0.0.0:4000 for Macs
            "api_key":"watsonx",
            "price" : [0,0]
        },
    ],
    "cache_seed": None,  # Disable caching.
}

phi2 = {
    "config_list": [
        {
            "model": "llama-3-8b",
            "base_url": "http://localhost:4000", #use http://0.0.0.0:4000 for Macs
            "api_key":"watsonx",
            "price" : [0,0]
        },
    ],
    "cache_seed": None,  # Disable caching.
}

jack = AssistantAgent(
    name="Jack(Phi-2)",
    llm_config=phi2,
    system_message="Your name is Jack and you are a comedian in a two-person comedy show.",
)

emma = AssistantAgent(
    name="Emma(Gemma)",
    llm_config=phi1,
    system_message="Your name is Emma and you are a comedian in two-person comedy show.",
)

jack.initiate_chat(emma, message="Emma, tell me a joke.", max_turns=2)
