Drop Unsupported Params

Drop unsupported OpenAI params by your LLM Provider.

Quick Start​

import litellm 
import os 

# set keys 
os.environ["COHERE_API_KEY"] = "co-.."

litellm.drop_params = True # 👈 KEY CHANGE

response = litellm.completion(
                model="command-r",
                messages=[{"role": "user", "content": "Hey, how's it going?"}],
                response_format={"key": "value"},
            )

LiteLLM maps all supported openai params by provider + model (e.g. function calling is supported by anthropic on bedrock but not titan).

See litellm.get_supported_openai_params("command-r") Code

If a provider/model doesn't support a particular param, you can drop it.

OpenAI Proxy Usage​

litellm_settings:
    drop_params: true

Pass drop_params in completion(..)​

Just drop_params when calling specific models 

import litellm 
import os 

# set keys 
os.environ["COHERE_API_KEY"] = "co-.."

response = litellm.completion(
                model="command-r",
                messages=[{"role": "user", "content": "Hey, how's it going?"}],
                response_format={"key": "value"},
                drop_params=True
            )

Specify params to drop​

To drop specific params when calling a provider (E.g. 'logit_bias' for vllm)

Use additional_drop_params

import litellm 
import os 

# set keys 
os.environ["COHERE_API_KEY"] = "co-.."

response = litellm.completion(
                model="command-r",
                messages=[{"role": "user", "content": "Hey, how's it going?"}],
                response_format={"key": "value"},
                additional_drop_params=["response_format"]
            )

additional_drop_params: List or null - Is a list of openai params you want to drop when making a call to the model.

Specify allowed openai params in a request​

Tell litellm to allow specific openai params in a request. Use this if you get a litellm.UnsupportedParamsError and want to allow a param. LiteLLM will pass the param as is to the model.

In this example we pass allowed_openai_params=["tools"] to allow the tools param.

Pass allowed_openai_params to LiteLLM Python SDK
await litellm.acompletion(
    model="azure/o_series/<my-deployment-name>",
    api_key="xxxxx",
    api_base=api_base,
    messages=[{"role": "user", "content": "Hello! return a json object"}],
    tools=[{"type": "function", "function": {"name": "get_current_time", "description": "Get the current time in a given location.", "parameters": {"type": "object", "properties": {"location": {"type": "string", "description": "The city name, e.g. San Francisco"}}, "required": ["location"]}}}]
    allowed_openai_params=["tools"],
)
