💡 Optimization Tips
Model Routing
Use cheaper models for 80% of tasks, premium only for complex reasoning…
Route simple queries to GPT-5 mini ($0.25/$2.00) and reserve Opus 4.8 ($5/$25) for complex tasks. Most teams save 60-70% with this strategy. Pro includes a personalized routing guide for your workload.
Batch Processing
Combine multiple API calls into batch requests to reduce overhead…
Batch API calls reduce per-request overhead by 30-50%. Group similar tasks, use async processing, and implement request queuing. Pro shows exact batch sizes for your usage pattern.
Response Caching
Cache common API responses to avoid redundant calls…
Implement semantic caching for repeated queries. Even 20% cache hit rate cuts costs significantly. Use embeddings-based similarity matching for fuzzy cache hits. Pro includes a caching implementation guide.
These are just 3 of 12 strategies. Pro users save an average of 40% on API costs.
Based on published API pricing. Actual costs may vary.

How This Calculator Works
Enter your expected usage — tokens per request, requests per day, and days per month — and the calculator shows your estimated cost per request, cost per 1K requests, and monthly total for any of 42 LLM models across 10 providers. Use the "Typical request" presets to quickly see what common workloads cost. It also suggests the cheapest alternative if a cheaper model can handle your workload.

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
