Streaming Protocol Enhancements

WebSocket Streaming API

// Real-time streaming with WebSocket
const deepseekStream = new DeepSeekWebSocket({
  apiKey: 'your-api-key',
  endpoint: 'wss://stream.deepseek.com/v1/chat'
});

deepseekStream.onMessage((chunk) => {
  // Process streaming tokens in real-time
  console.log('Streaming token:', chunk.token);
  updateUI(chunk.token);
});

deepseekStream.onComplete((response) => {
  console.log('Stream complete:', response.full_text);
  console.log('Total time:', response.processing_time + 'ms');
});

// Start streaming conversation
deepseekStream.send({
  messages: [
    { role: "user", content: "Explain quantum computing" }
  ],
  stream: true,
  max_tokens: 1000
});

Server-Sent Events (SSE)

import asyncio
from deepseek import AsyncClient

async def stream_response():
    client = AsyncClient(api_key="your-api-key")
    
    async for chunk in client.chat.completions.create(
        model="deepseek-chat",
        messages=[
            {"role": "user", "content": "Write a story about AI"}
        ],
        stream=True,
        stream_options={"include_usage": True}
    ):
        if chunk.choices[0].delta.content:
            print(chunk.choices[0].delta.content, end="", flush=True)
            # Process each token immediately
            await process_token(chunk.choices[0].delta.content)

# Run the streaming function
asyncio.run(stream_response())

Performance Optimizations

Predictive Token Generation

# Advanced streaming with predictive generation
from deepseek import StreamingClient

client = StreamingClient(
    api_key="your-api-key",
    enable_prediction=True,
    prediction_depth=5  # Predict 5 tokens ahead
)

stream = client.chat.stream(
    messages=[{"role": "user", "content": "Explain machine learning"}],
    stream_config={
        "buffer_size": 10,
        "prediction_enabled": True,
        "adaptive_quality": True,
        "target_latency": 30  # Target 30ms latency
    }
)

for token in stream:
    print(f"Token: {token.content}")
    print(f"Confidence: {token.confidence}")
    print(f"Latency: {token.latency}ms")
    print(f"Predicted next: {token.predicted_tokens}")

Adaptive Quality Streaming

# Quality-aware streaming
stream_config = {
    "quality_mode": "adaptive",
    "min_quality": 0.85,
    "max_latency": 50,
    "fallback_strategy": "maintain_speed"
}

response = client.chat.stream(
    messages=messages,
    stream_config=stream_config
)

for chunk in response:
    print(f"Quality score: {chunk.quality_score}")
    print(f"Processing time: {chunk.processing_time}ms")
    if chunk.quality_score < 0.9:
        print("Quality adjusted for speed optimization")

Real-Time Applications

                this.showTypingIndicator(chunk.processing_time);
            }

Getting Started

Quick Start Guide

1. Enable Real-Time Streaming

# Install the streaming SDK
pip install deepseek-streaming

# Set up your API key
export DEEPSEEK_API_KEY="your-api-key-here"

2. First Streaming Request

from deepseek_streaming import StreamingClient

client = StreamingClient()

# Start your first real-time stream
for chunk in client.chat.stream(
    messages=[{"role": "user", "content": "Hello, world!"}],
    real_time=True
):
    print(chunk.content, end='', flush=True)

3. Monitor Performance

# Enable performance monitoring
stream = client.chat.stream(
    messages=messages,
    real_time=True,
    monitor_performance=True
)
