Smart Cost Control for GenAI with AWS Intelligent Prompt Routing
Generative AI has quickly moved from experimental to essential. Today’s product teams are rolling out intelligent features like context-aware chatbots, auto-summarization tools, and document understanding APIs as standard offerings in SaaS applications. These capabilities deliver clear user value, but they come with a hidden cost. Consider a typical example: a growing SaaS platform integrates a GenAI-powered help assistant. Within weeks, usage surges as users engage with the feature across workflows. Prompt volume rises from 50,000 per week to over 400,000, with traffic covering everything from password resets to policy breakdowns. But soon after, AWS costs spike significantly from $8,500 to $67,000 in a single month, all tied to model inference.
