Use the Comparison ToolTips to Reduce Your API Costs
The calculator often reveals that a cheaper model can handle your workload. Here are the biggest cost-saving strategies:
- Use budget models for simple tasks: GPT-4o mini ($0.15/$0.60) handles 80% of chatbot requests at 1/17th the cost of GPT-4o
- Optimize prompts: Shorter prompts = fewer input tokens = lower costs
- Set token limits: Don't let models generate 4000 tokens when 200 will do
- Cache responses: Identical prompts can be cached to eliminate redundant API calls
