Step-by-Step Implementation Guide

3.1 Python Quickstart (3-Minute Setup)

# Requires transformers>=4.51.0
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen3-235B-A22B-Instruct-2507",
    torch_dtype="auto",  # Automatic precision selection
    device_map="auto"    # Automatic GPU allocation
)

# Build conversation format (supports 262K context)
messages = [{"role": "user", "content": "Analyze this genomics research report..."}]
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt")

# Generate response (recommended max_new_tokens=16384)
outputs = model.generate(inputs, max_new_tokens=16384)
print(tokenizer.decode(outputs[0]))

3.2 Production Deployment

# Option 1: vLLM Acceleration (Recommended)
vllm serve Qwen/Qwen3-235B-A22B-Instruct-2507 \
  --tensor-parallel-size 8 \
  --max-model-len 262144  # Full context support!

# Option 2: SGLang Deployment
python -m sglang.launch_server \
  --model-path Qwen/Qwen3-235B-A22B-Instruct-2507 \
  --tp 8 \
  --context-length 262144

Memory Optimization Tip: Reduce --max-model-len to 32768 if encountering OOM errors

Real-World Agent Implementation

4.1 Building a Research Assistant

from qwen_agent.agents import Assistant

# Configure tools (Code interpreter + document retrieval)
tools = [
    'code_interpreter',  # Built-in Python environment
    {'mcpServers': {
        "fetch": {
            "command": "uvx",
            "args": ["mcp-server-fetch"]  # Document retrieval tool
        }
    }}
]

# Create AI assistant
assistant = Assistant(
    llm={'model': 'Qwen3-235B-A22B-Instruct-2507'},
    function_list=tools
)

# Execute research task
response = assistant.run([{
    'role': 'user',
    'content': 'Analyze experimental data from https://arxiv.org/pdf/2405.1234.pdf and plot graphs using Python'
}])
