Running large language models like Gemini or OpenAI's models in production for a consumer application involves significant costs and technical challenges beyond simple API calls. Key issues include managing token costs, reducing latency through caching, ensuring reliability against provider outages, and mitigating the blast radius of bugs or traffic spikes. The author found that semantic caching based on query embeddings, rather than exact text matching, reduced costs by 40-50% without impacting answer quality. For image processing, using perceptual hashing before embedding can further optimize caching and reduce expenses. AI
