  • 问答（Q&A）
response = client.chat.completions.create(
  model="deepseek-ai/DeepSeek-V4.1-Flash",
  messages=[{"role": "user", "content": "How many days are in October?"}]

1. **登录问题**：客户因密码问题及缺少重置链接而无法登录。  
2. **密码重置建议**：客服确认发送后再次转发重置邮件。  
3. **快速协助**：客户改用 Google 登录后解决。

控制回复长度

  • max_tokens = 5
response = client.chat.completions.create(
  model="deepseek-ai/DeepSeek-V4.1-Flash",
  messages=[{"role":"user",
      "content":"Write a haiku about AI."}],
  max_tokens=5
)


**Silent circuits hum
  • max_tokens = 30
response = client.chat.completions.create(
    model="deepseek-ai/DeepSeek-V4.1-Flash",
    messages=[{"role":"user",
      "content":"Write a haiku about AI."}],
    max_tokens=30
)


**Silent circuits hum,**  
**thoughts of light and logic bloom—**  
**minds beyond our own.**

理解 token

$$

  • Token：AI 用于理解和解析文本的最小文本单位

$$

句子 "How can the OpenAI API deliver business value?"，每个 token 用不同颜色高亮。

成本计算

 

  • API 使用成本取决于平台、模型和 token 数量 💰

    • 模型按 cost/tokens 计价
    • 输入与输出 token 的单价可能不同

  • 提高 max_tokens 会增加成本 📈

成本计算

prompt = f"""Summarize the customer support chat 
             in three concise key points: {text}"""

max_tokens = 500

response = client.chat.completions.create(
    model="deepseek-ai/DeepSeek-V4.1-Flash",
    messages=[{"role": "user", "content": prompt}], 
    max_tokens=max_tokens
)

成本计算

# Define price per token
input_token_price = 2.1 / 1_000_000
output_token_price = 4.4 / 1_000_000

# Extract token usage
input_tokens = response.usage.prompt_tokens

output_tokens = max_tokens

# Calculate cost
cost = (input_tokens * input_token_price + output_tokens * output_token_price)
print(f"Estimated cost: ${cost}")

Estimated cost: $0.0153964
