90% Cost Reduction! Optimizing Gemini API for Large-Scale Audio Analysis

This is a brilliant showcase of leveraging native Multimodal capabilities to solve complex business challenges while dramatically reducing costs. By skipping traditional transcription and feeding long audio directly into Gemini 2.5 Flash, the team achieved a 90% cost reduction and eliminated hallucinations caused by lengthy text contexts. The clever 'subtraction' design philosophy proves that focusing on practical, high-volume analysis yields far better results than striving for unachievable perfections.
