Python SDK for the Backboard API - Build conversational AI applications with persistent memory and intelligent document processing

Backboard Python SDK

A developer-friendly Python SDK for the Backboard API. Build conversational AI applications with persistent memory and intelligent document processing.

New to Backboard? We include $5 in free credits to get you started and support 1,800+ LLMs across major providers.

New in v1.4.8

• Multiple Embedding Models: Support for custom embedding providers and models (OpenAI, Google, Cohere, etc.)
• Configurable Embedding Dimensions: Set custom embedding dimensions for advanced use cases
• Memory Support: Add persistent memory to assistants with automatic context retrieval
• Memory Modes: Control memory behavior with Auto, Readonly, and off modes
• Memory Statistics: Track usage and limits
• Response parity: SDK now surfaces retrieved_files / memory_operation_id for non-streaming responses and parses metadata_ consistently.

Installation

pip install backboard-sdk

Quick Start

import asyncio
from backboard import BackboardClient

async def main():
    client = BackboardClient(api_key="your_api_key_here")

    assistant = await client.create_assistant(
        name="Support Bot",
        system_prompt="You are a helpful customer support assistant",
    )

    thread = await client.create_thread(assistant.assistant_id)

    response = await client.add_message(
        thread_id=thread.thread_id,
        content="Hello! Can you help me with my account?",
        llm_provider="openai",
        model_name="gpt-4o",
        stream=False,
    )

    print(response.content)

    # Streaming
    async for event in await client.add_message(
        thread_id=thread.thread_id,
        content="Stream me a short response",
        stream=True,
    ):
        if event.get("type") == "content_streaming":
            print(event.get("content", ""), end="", flush=True)

if __name__ == "__main__":
    asyncio.run(main())

Tool Integration (Simplified in v1.3.3)

Tool Definitions

# Use plain JSON objects (no verbose SDK classes needed!)
tools = [
    {
        "type": "function",
        "function": {
            "name": "get_weather",
            "description": "Get current weather",
            "parameters": {
