Hidden Costs to Consider

1. Output Token Ratio

Output tokens cost 3-8x more than input. A model with $1/$8 pricing costs more than $2/$6 if your app generates long responses.

2. Context Window Pricing

Some providers charge extra for long context. Google and Anthropic include full context at base price—OpenAI varies by model.

3. Caching Availability

• OpenAI: Automatic, 50% savings
• Anthropic: Manual, 90% savings
• Google: Automatic, 50% savings
• Others: Limited or none

4. Rate Limits

Enterprise rate limits vary significantly. DeepSeek and smaller providers may have lower limits than OpenAI/Anthropic.

Cost Optimization Strategies

1. Model Routing

Route 70%+ of queries to budget models. Our research shows model routing can save 85% while maintaining 95% quality.

2. Prompt Caching

Enable prompt caching for 50-90% savings on repeated context.

3. Batch Processing

Use OpenAI's Batch API for 50% discount on non-urgent workloads.

4. Output Control

Set max_tokens and use structured output to reduce expensive output tokens.
