Usage Steps

💡 Practical Tips

✅ Recommended Practices

1. Choose the Right Model:

   • Complex tasks: Use GPT-4o or Llama-3.1-405B
   • Daily conversations: Use GPT-4o-mini or Llama-3.1-8B
   • Chinese tasks: Use DeepSeek-R1
   • Knowledge retrieval: Use Cohere Command-R+

2. Optimize Prompts:

   • Provide clear context and background
   • Use specific examples to illustrate expected output
   • Describe complex tasks step by step
   • Explicitly specify output format

3. Use Rate Limits Wisely:

   • Understand each model’s limits beforehand
   • Switch to other models when reaching limits
   • Avoid meaningless repeated requests
   • Merge similar questions into one

🎯 Best Practices

Efficient Questioning:

• ✅ Be specific and clear, avoid vagueness
• ✅ Provide necessary background and context
• ✅ Use step-by-step approach for complex tasks
• ❌ Avoid overly broad questions
• ❌ Don’t provide too much irrelevant information

Maximize Free Quota:

• Use Playground to test and optimize prompts
• Use API after determining best model
• Compare effects of different models
• Learn and study model characteristics

Model Comparison:

Try different models for same question:
1. Use GPT-4o for high-quality answers
2. Use Llama-3.1-70B to compare open-source performance
3. Use DeepSeek-R1 to see Chinese optimization
4. Choose the model that best fits your needs

⚠️ Notes

1. Rate Limits: Need to wait for quota reset after reaching limit, allocate usage wisely. Quotas are reference values, please check official page for actual limits.
