Tip 2

EnableStreaming Output，ResponseSmoother

stream=True makes AI Displays Word by Word Like Typing，No Need to Wait for Complete Output

❌ Standard Mode（Wait for FullOutput）
response = client.chat.completions.create(
  model="deepseek-ai/DeepSeek-V3",
  messages=[...],
  stream=False # waits 3-10...
)
print(response.choices[0].message.content)
✅ Streaming Mode（Instant Display）
response = client.chat.completions.create(
  model="deepseek-ai/DeepSeek-V3",
  messages=[...],
  stream=True # Starts Displaying Immediately
)
for chunk in response:
  print(chunk.choices[0].delta.content, end="")

Adjust Temperature Parameters

Control AI Output's Creativity，Different Tasks Need DifferentSettings

0.0
temperature=0 Most Deterministic
Code generation、Data Processing、Format Conversion → Consistent Results Every Time，Accurate and Reliable
0.7
temperature=0.7 Balanced（Default Recommendation）
Daily Q&A、Copywriting、Translation → Accurate and Natural，Most Common
1.2
temperature=1.2 Most Creative
Story Writing、Brainstorming、Ad Copy → Surprisingly creative, but may go off track.
Tip 5

Batch Processing SignificantlyCost-Saving

Combine Multiple Small QuestionsCombine into oneRequest，Reduce API CallTimeCount

❌ Inefficient Approach（MultipleRequest）
# 3TimeAPICall，3Basicscost
result1 = ask("Translation：Hello")
result2 = ask("Translation：World")
result3 = ask("Translation：Python")
✅ Efficient Approach（OneRequest）
# 1TimeAPICall，Save67%cost
result = ask(
  "Translate the following words to Chinese,
  return as JSON.：
  Hello, World, Python"
)
💡 Combine tasks into one prompt. Save 2/3 of the cost, and it's even faster.
Key Concepts

How Tokens Billing Work?

🔤
Token ≈ Token = Basic Unit of Text
English: ~4 characters = 1 Token. Chinese: ~1-2 characters = 1 Token. = 1 Token
📊
Input + OutputBoth Billed
Your messages (including chat history) = input Tokens. AI replies = output Tokens. Both are billed.
✂️
Cost-SavingTip：Control Context Length
Don't let conversations grow indefinitely. Start fresh chats regularly to avoid sending large chat histories to the AI.
Troubleshooting

Troubleshoot How？

🔴
401 Unauthorized
