OpenWebUI Client

A client library for the OpenWebUI API, compatible with the OpenAI Python SDK but with extensions specific to OpenWebUI features.

Installation

pip install openwebui-client

Quick Start

from openwebui_client import OpenWebUIClient

# Initialize client
client = OpenWebUIClient(
    api_key="your_api_key",  # Optional if set in environment variable
    base_url="http://your-openwebui-instance:5000",
    default_model="gpt-4"
)

# Basic chat completion
response = client.chat.completions.create(
    model="gpt-4",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Hello, world!"}
    ]
)
print(response.choices[0].message.content)

Using Function Calling / Tools

The client supports OpenAI-compatible function calling with tools:

# Direct tool usage with chat completions
response = client.chat.completions.create(
    model="your_model",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "What is the current time?"}
    ],
    tools=[
        {
            "type": "function",
            "function": {
                "name": "get_current_time",
                "description": "Get the current time.",
                "parameters": {
                    "type": "object",
                    "properties": {},
                    "required": [],
                },
            },
        }
    ],
)

# Check if the model used tools
if response.choices[0].message.tool_calls:
    tool_call = response.choices[0].message.tool_calls[0]
    print(f"Tool called: {tool_call.function.name}")

Using the Tool Registry

The client includes a tool registry for easier management of tools:

# Define tool functions
def get_weather(location: str, unit: str = "celsius") -> str:
    """Get the current weather in a given location.

    Args:
        location: The location to get weather for
        unit: The temperature unit to use (celsius or fahrenheit)

    Returns:
        str: A string describing the current weather
    """
    return f"The weather in {location} is sunny and 25°{unit[0]}"

# Register tools with the client
client.tool_registry.register(get_weather)

# Use chat_with_tools for automatic tool handling
response = client.chat_with_tools(
    messages=[{"role": "user", "content": "What's the weather like in Toronto?"}],
    max_tool_calls=5,
)

print(response)  # Will contain the final response after any tool calls

File Operations

# Upload a file to OpenWebUI
uploaded_file = client.files.from_path(file)

# Upload multiple files to OpenWebUI
with open("document.pdf", "rb") as file:
    uploaded_files = client.files.from_paths(
        files=[
            (file1, None),
            (file2, {"xMetaField": "xMetaValue"})
        ]
    )

uploaded_files.append(uploaded_file)

# Use file with chat completion
response = client.chat.completions.create(
    model="gpt-4",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Summarize this document for me."}
    ],
    files=uploaded_files
)
