1. Start with Gemini 2.0 Flash
For most use cases, Gemini 2.0 Flash offers 80-90% of GPT-4o's quality at 3% of the cost. Test it first before upgrading to premium models.
2. Use Context Caching
Both providers offer caching. Gemini's context caching can reduce costs by 75-90% for repeated large contexts (documentation, knowledge bases).
3. Leverage Gemini's Huge Context
Instead of multiple API calls with GPT-4o, process entire datasets in one Gemini 1.5 Pro request. Saves on API overhead and reduces complexity.
4. Mix and Match Models
Use Gemini Flash for high-volume tasks, GPT-4o for critical reasoning. Hybrid approaches can save 60-80% while maintaining quality where it matters.
