Developers waste 60% of LLM API spend by using wrong models

By PulseAugur Editorial · [2 sources] ·

A recent analysis of one million LLM API calls revealed that a significant portion of AI spending is being wasted due to developers defaulting to more expensive, powerful models than necessary for their tasks. The study found that 60-70% of API calls could be handled by cheaper models, with potential savings of up to 95% by implementing model routing and prompt caching strategies. This inefficiency contributes to rising AI costs, with average monthly spend reaching $85,500 per company in 2025. AI

IMPACT Highlights significant cost-saving opportunities for AI operators through optimized model selection and routing.
