tensorchat-streaming 1.0.3

Framework-agnostic Python client for Tensorchat.io streaming API

Tensorchat Streaming Python Client

Framework-agnostic Python client for Tensorchat.io streaming API. Process multiple LLM prompts concurrently with real-time streaming responses using async/await patterns.

✨ Features

• Framework Agnostic: Works with asyncio, FastAPI, Django, Flask, or any Python framework
• Real-time Streaming: Get live updates as tensors are processed with async streaming
• Concurrent Processing: Handle multiple prompts simultaneously with true concurrency
• Type Safety: Fully typed with dataclasses and comprehensive type hints
• Configurable: Throttling, custom endpoints, and robust error handling
• Lightweight: Minimal dependencies (only aiohttp required)
• Multi-Tensor Support: Process up to 8 concurrent tensor requests

🚀 Quick Start

Installation

pip install tensorchat-streaming

Basic Usage

async def main():
    # Configure the client
    config = TensorchatConfig(
        api_key="your-api-key-from-tensorchat.io",
        base_url="https://api.tensorchat.io"  # Correct API endpoint
    )
    
    # Define callbacks to handle streaming data
    def on_chunk(data):
        print(f"Tensor {data.index}: {data.chunk}", end="", flush=True)
    
    def on_complete(data):
        print(f"\n✅ All {data.total_tensors} tensors completed!")
    
    callbacks = StreamCallbacks(
        on_tensor_chunk=on_chunk,
        on_complete=on_complete
    )
    
    # Create and execute request
    async with TensorchatStreaming(config) as client:
        request = StreamRequest(
            context="You are a helpful assistant.",
            model="google/gemini-2.5-flash-lite",
            tensors=[
                TensorConfig(messages="Explain quantum computing in simple terms"),
