IBM watsonx.ai

LiteLLM supports all IBM watsonx.ai foundational models and embeddings.

Environment Variables​

os.environ["WATSONX_URL"] = ""  # (required) Base URL of your WatsonX instance
# (required) either one of the following:
os.environ["WATSONX_APIKEY"] = "" # IBM cloud API key
os.environ["WATSONX_TOKEN"] = "" # IAM auth token
# optional - can also be passed as params to completion() or embedding()
os.environ["WATSONX_PROJECT_ID"] = "" # Project ID of your WatsonX instance
os.environ["WATSONX_DEPLOYMENT_SPACE_ID"] = "" # ID of your deployment space to use deployed models

See here for more information on how to get an access token to authenticate to watsonx.ai.

Usage​

Open In Colab
import os
from litellm import completion

os.environ["WATSONX_URL"] = ""
os.environ["WATSONX_APIKEY"] = ""

## Call WATSONX `/text/chat` endpoint - supports function calling
response = completion(
  model="watsonx/meta-llama/llama-3-1-8b-instruct",
  messages=[{ "content": "what is your favorite colour?","role": "user"}],
  project_id="<my-project-id>" # or pass with os.environ["WATSONX_PROJECT_ID"]
)

## Call WATSONX `/text/generation` endpoint - not all models support /chat route. 
response = completion(
  model="watsonx/ibm/granite-13b-chat-v2",
  messages=[{ "content": "what is your favorite colour?","role": "user"}],
  project_id="<my-project-id>"
)

Usage - Streaming​

import os
from litellm import completion

os.environ["WATSONX_URL"] = ""
os.environ["WATSONX_APIKEY"] = ""
os.environ["WATSONX_PROJECT_ID"] = ""

response = completion(
  model="watsonx/meta-llama/llama-3-1-8b-instruct",
  messages=[{ "content": "what is your favorite colour?","role": "user"}],
  stream=True
)
for chunk in response:
  print(chunk)

Example Streaming Output Chunk​

{
  "choices": [
    {
      "finish_reason": null,
      "index": 0,
      "delta": {
        "content": "I don't have a favorite color, but I do like the color blue. What's your favorite color?"
      }
    }
  ],
  "created": null,
  "model": "watsonx/ibm/granite-13b-chat-v2",
  "usage": {
    "prompt_tokens": null,
    "completion_tokens": null,
    "total_tokens": null
  }
}

Usage - Models in deployment spaces​

Models that have been deployed to a deployment space (e.g.: tuned models) can be called using the deployment/<deployment_id> format (where <deployment_id> is the ID of the deployed model in your deployment space).

The ID of your deployment space must also be set in the environment variable WATSONX_DEPLOYMENT_SPACE_ID or passed to the function as space_id=<deployment_space_id>. 

import litellm
response = litellm.completion(
    model="watsonx/deployment/<deployment_id>",
    messages=[{"content": "Hello, how are you?", "role": "user"}],
    space_id="<deployment_space_id>"
)

Usage - Embeddings​

LiteLLM also supports making requests to IBM watsonx.ai embedding models. The credential needed for this is the same as for completion.

from litellm import embedding

response = embedding(
    model="watsonx/ibm/slate-30m-english-rtrvr",
    input=["What is the capital of France?"],
    project_id="<my-project-id>"
)
print(response)
# EmbeddingResponse(model='ibm/slate-30m-english-rtrvr', data=[{'object': 'embedding', 'index': 0, 'embedding': [-0.037463713, -0.02141933, -0.02851813, 0.015519324, ..., -0.0021367231, -0.01704561, -0.001425816, 0.0035238306]}], object='list', usage=Usage(prompt_tokens=8, total_tokens=8))

OpenAI Proxy Usage​

Here's how to call IBM watsonx.ai with the LiteLLM Proxy Server

1. Save keys in your environment​

export WATSONX_URL=""
export WATSONX_APIKEY=""
export WATSONX_PROJECT_ID=""

2. Start the proxy​

$ litellm --model watsonx/meta-llama/llama-3-8b-instruct

# Server running on http://0.0.0.0:4000

3. Test it​

curl --location 'http://0.0.0.0:4000/chat/completions' \
--header 'Content-Type: application/json' \
--data ' {
      "model": "llama-3-8b",
      "messages": [
        {
          "role": "user",
          "content": "what is your favorite colour?"
        }
      ]
    }
'

Authentication​

Passing credentials as parameters​

You can also pass the credentials as parameters to the completion and embedding functions.

import os
from litellm import completion

response = completion(
            model="watsonx/ibm/granite-13b-chat-v2",
            messages=[{ "content": "What is your favorite color?","role": "user"}],
            url="",
            api_key="",
            project_id=""
)
