DeepSeek-V3.1 发布，迈向 Agent 时代的第一步
混合推理架构、更高思考效率与增强的 Agent 能力——DeepSeek-V3.1 的发布不仅是技术迭代，更是人工智能向智能体时代迈进的关键一步。
一、DeepSeek-V31 总体架构与核心特性
1.1 混合推理架构：思考模式与非思考模式的统一
DeepSeek-V3.1 引入了混合推理架构，使单一模型能够同时支持思考模式（Think Mode） 与非思考模式（Non-Think Mode）。这种架构的核心在于动态路径选择机制，模型根据任务复杂度自主决定是否启动思考链推理。
思考模式通过扩展的推理步骤处理复杂问题，显著提升了解题能力；非思考模式则优化了响应速度，适合简单查询和实时交互场景。用户可通过官方 App 或网页端的"深度思考"按钮自由切换这两种模式。
import requests
import json
# 非思考模式调用
def deepseek_chat_api(messages, model="deepseek-chat"):
url = "https://api.deepseek.com/v1/chat/completions"
headers = {
"Authorization": "Bearer YOUR_API_KEY",
"Content-Type": "application/json"
}
data = {
"model": model,
"messages": messages,
"max_tokens": 2048,
"temperature": 0.7
}
response = requests.post(url, headers=headers, json=data)
return response.json()
# 思考模式调用
def deepseek_reasoner_api(messages, model="deepseek-reasoner"):
url = "https://api.deepseek.com/v1/chat/completions"
headers = {
"Authorization": "Bearer YOUR_API_KEY",
"Content-Type": "application/json"
}
data = {
"model": model,
"messages": messages,
"max_tokens": 4096,
"temperature": 0.3,
"reasoning_effort": "high" # 控制推理强度的参数
}
response = requests.post(url, headers=headers, json=data)
return response.json()
# 使用示例
messages = [
{"role": "system", "content": "你是一个有帮助的AI助手"},
{"role": "user", "content": "请解释量子计算中的Shor算法及其对密码学的影响"}
]
# 根据需求选择模式
response = deepseek_reasoner_api(messages) # 复杂问题使用思考模式
# 或 response = deepseek_chat_api(messages) # 简单问题使用非思考模式
1.2 上下文窗口扩展至128K
DeepSeek-V3.1 将上下文长度扩展至 128K tokens，相比前代模型的32K有了显著提升。这一扩展使模型能够处理更长的文档、维持更复杂的多轮对话以及进行深度的上下文分析。
def process_long_document(document_text, query):
"""
处理长文档并回答问题的示例函数
"""
# 分割长文档以适应模型上下文（实际使用中可能需要更复杂的分块策略）
chunk_size = 120000 # 保留8K tokens给对话上下文
chunks = [document_text[i:i+chunk_size] for i in range(0, len(document_text), chunk_size)]
responses = []
for chunk in chunks:
messages = [
{"role": "system", "content": "你是一个文档分析专家，基于提供的文档内容回答问题"},
{"role": "user", "content": f"文档内容：{chunk}\n\n问题：{query}"}
]
response = deepseek_reasoner_api(messages)
responses.append(response['choices'][0]['message']['content'])
# 综合所有分块的回答（实际应用中可能需要更复杂的综合逻辑）
final_response = "\n\n".join(responses)
return final_response
二、思考效率的大幅提升
2.1 思维链压缩技术
DeepSeek-V3.1 通过思维链压缩（Chain-of-Thought Compression） 训练，在保持任务性能的前提下，将思考模式下的输出token数量减少了20%-50%。这一突破显著降低了推理成本并提高了响应速度。
import time
from collections import defaultdict
# 思考效率对比测试
def test_reasoning_efficiency(questions, model_type="reasoner"):
"""
测试不同模型的推理效率和效果
"""
results = defaultdict(list)
for question in questions:
messages = [{"role": "user", "content": question}]
start_time = time.time()
if model_type == "reasoner":
response = deepseek_reasoner_api(messages)
else:
response = deepseek_chat_api(messages)
end_time = time.time()
# 分析响应
content = response['choices'][0]['message']['content']
token_count = response['usage']['total_tokens']
processing_time = end_time - start_time
results['questions'].append(question)
results['responses'].append(content)
results['token_counts'].append(token_count)
results['processing_times'].append(processing_time)
return results
# 测试问题集
test_questions = [
"证明勾股定理并解释其历史意义",
"如何用Python实现一个简单的神经网络？",
"解释相对论的基本原理和现实应用",
"分析当前全球经济形势和未来趋势"
]
# 运行测试
reasoner_results = test_reasoning_efficiency(test_questions, "reasoner")
chat_results = test_reasoning_efficiency(test_questions, "chat")
# 输出效率对比
print("思考模式平均token数:", sum(reasoner_results['token_counts'])/len(test_questions))
print("非思考模式平均token数:", sum(chat_results['token_counts'])/len(test_questions))
print("思考模式平均响应时间:", sum(reasoner_results['processing_times'])/len(test_questions))
print("非思考模式平均响应时间:", sum(chat_results['processing_times'])/len(test_questions))
2.2 自适应推理机制
DeepSeek-V3.1 引入了自适应推理机制，模型能够根据问题复杂度动态调整推理深度：
class AdaptiveReasoner:
def __init__(self):
self.complexity_threshold = 0.7 # 复杂度阈值
def estimate_complexity(self, question):
"""
估计问题的复杂度（简化示例）
"""
complexity_indicators = [
len(question.split()) > 20, # 问题长度
any(keyword in question.lower() for keyword in
['解释', '分析', '证明', '如何实现', '为什么']), # 复杂问题关键词
'?' in question and ':' in question # 多子问题特征
]
return sum(complexity_indicators) / len(complexity_indicators)
def process_question(self, question):
"""
根据问题复杂度选择处理模式
"""
complexity = self.estimate_complexity(question)
if complexity > self.complexity_threshold:
print(f"问题复杂度高({complexity:.2f})，使用思考模式")
return deepseek_reasoner_api([{"role": "user", "content": question}])
else:
print(f"问题复杂度低({complexity:.2f})，使用非思考模式")
return deepseek_chat_api([{"role": "user", "content": question}])
# 使用自适应推理
reasoner = AdaptiveReasoner()
response = reasoner.process_question("请详细解释Transformer架构的自注意力机制及其数学基础")
三、增强的Agent能力与工具使用
3.1 函数调用（Function Calling）能力
DeepSeek-V3.1 支持严格模式的函数调用，确保输出的函数参数符合schema定义，大大提升了Agent在复杂任务中的可靠性。
import json
from typing import List, Dict, Any
def get_current_weather(location: str, unit: str = "celsius") -> Dict[str, Any]:
"""获取当前天气信息"""
# 模拟天气数据
weather_data = {
"location": location,
"temperature": 22 if unit == "celsius" else 72,
"unit": unit,

"humidity": 65
}
return weather_data
def get_stock_price(symbol: str) -> Dict[str, Any]:
"""获取股票价格"""
# 模拟股票数据
stock_data = {
"symbol": symbol,
"price": 150.75,
"change": +2.5,
"change_percent": +1.69
}
return stock_data
# 可供调用的函数列表
available_functions = {
"get_current_weather": get_current_weather,
"get_stock_price": get_stock_price
}

]
def run_conversation_with_functions(user_input):
"""运行带有函数调用的对话"""
messages = [{"role": "user", "content": user_input}]
# 第一次调用，获取函数调用请求
response = deepseek_reasoner_api(
messages,
function_call="auto",
functions=function_schemas
)
response_message = response['choices'][0]['message']
# 检查是否请求调用函数
if 'function_call' in response_message:
function_name = response_message['function_call']['name']
function_args = json.loads(response_message['function_call']['arguments'])
# 调用相应函数
function_to_call = available_functions[function_name]
function_response = function_to_call(**function_args)
# 将函数响应添加到消息中
messages.append(response_message)
messages.append({
"role": "function",
"name": function_name,
"content": json.dumps(function_response)
})
# 第二次调用，让模型基于函数响应生成最终回答
second_response = deepseek_reasoner_api(messages)
return second_response['choices'][0]['message']['content']
else:
return response_message['content']
# 使用示例
weather_query = "北京现在的天气怎么样？用摄氏度表示。"
weather_response = run_conversation_with_functions(weather_query)
print(weather_response)
stock_query = "AAPL的股票价格是多少？"
stock_response = run_conversation_with_functions(stock_query)
print(stock_response)
3.2 复杂工具使用与工作流编排
DeepSeek-V3.1 在复杂工具使用和工作流编排方面有显著提升，特别是在编程和终端操作任务中：

try:
result = subprocess.run(
command,
shell=True,
capture_output=True,
text=True,
timeout=30
)
return {
"success": result.returncode == 0,
"return_code": result.returncode,
"stdout": result.stdout,

analysis_results = {}
# 获取文件结构
find_result = execute_terminal_command(f"find {repo_path} -type f -name \"*.py\" | head -20")
if find_result['success']:
analysis_results['python_files'] = find_result['stdout'].split('\n')
# 分析导入依赖
imports_result = execute_terminal_command(
f"grep -r \"^import\\|^from\" {repo_path} --include=\"*.py\" | head -10"
)
if imports_result['success']:
analysis_results['imports'] = imports_result['stdout']
return analysis_results
# 扩展可用函数
available_functions["execute_terminal_command"] = execute_terminal_command
available_functions["analyze_code_repository"] = analyze_code_repository

chunk = json.loads(event.data)
if 'choices' in chunk and len(chunk['choices']) > 0:
delta = chunk['choices'][0].get('delta', {})
if 'content' in delta:
content = delta['content']
print(content, end='', flush=True)
full_response += content
