Ollama

LiteLLM supports all models from Ollama

info

We recommend using ollama_chat for better responses.

Pre-requisites

Ensure you have your ollama server running

Example usage

from litellm import completion

response = completion(
    model="ollama/llama2", 
    messages=[{ "content": "respond in 20 words. who are you?","role": "user"}], 
    api_base="http://localhost:11434"
)
print(response)

Example usage - Streaming

from litellm import completion

response = completion(
    model="ollama/llama2", 
    messages=[{ "content": "respond in 20 words. who are you?","role": "user"}], 
    api_base="http://localhost:11434",
    stream=True
)
print(response)
for chunk in response:
    print(chunk['choices'][0]['delta'])

Example usage - Streaming + Acompletion

Ensure you have async_generator installed for using ollama acompletion with streaming

pip install async_generator

async def async_ollama():
    response = await litellm.acompletion(
        model="ollama/llama2", 
        messages=[{ "content": "what's the weather" ,"role": "user"}], 
        api_base="http://localhost:11434", 
        stream=True
    )
    async for chunk in response:
        print(chunk)

# call async_ollama
import asyncio
asyncio.run(async_ollama())

Example Usage - JSON Mode

To use ollama JSON Mode pass format="json" to litellm.completion()

from litellm import completion
response = completion(
  model="ollama/llama2",
  messages=[
      {
          "role": "user",
          "content": "respond in json, what's the weather"
      }
  ],
  max_tokens=10,
  format = "json"
)

Example Usage - Tool Calling

To use ollama tool calling, pass tools=[{..}] to litellm.completion()

SDK
PROXY

from litellm import completion
import litellm 

## [OPTIONAL] REGISTER MODEL - not all ollama models support function calling, litellm defaults to json mode tool calls if native tool calling not supported.

# litellm.register_model(model_cost={
#                 "ollama_chat/llama3.1": { 
#                   "supports_function_calling": true
#                 },
#             })

tools = [
  {
    "type": "function",
    "function": {
      "name": "get_current_weather",
      "description": "Get the current weather in a given location",
      "parameters": {
        "type": "object",
        "properties": {
          "location": {
            "type": "string",

          },
          "unit": {"type": "string", "enum": ["celsius", "fahrenheit"]},
        },
        "required": ["location"],
      },
    }
  }
]

messages = [{"role": "user", "content": "What's the weather like in Boston today?"}]


response = completion(
  model="ollama_chat/llama3.1",
  messages=messages,
  tools=tools
)

Setup config.yaml

model_list:
  - model_name: "llama3.1"             
    litellm_params:
      model: "ollama_chat/llama3.1"
    model_info:
      supports_function_calling: true

Start proxy

litellm --config /path/to/config.yaml

Test it!

        }
      }
    }
  ],
  "tool_choice": "auto",
  "stream": true
}'

Using ollama `api/chat`

In order to send ollama requests to POST /api/chat on your ollama server, set the model prefix to ollama_chat

from litellm import completion

response = completion(
    model="ollama_chat/llama2", 
    messages=[{ "content": "respond in 20 words. who are you?","role": "user"}], 
)
print(response)
