How We Cut AI Costs by 73% While Improving Quality: Building Cost-Effective LLM Features
The AI proposal generator faced significant losses in its second month of operation, with an OpenAI bill of $3,200 against only $1,800 in revenue, resulting in a gross margin of negative 78%. After six months of optimization, the processing volume increased tenfold while the cost per request decreased to 27% of the original. The current gross margin stands at 62%, and response quality improved from 4.3/5 to 4.6/5. The team learned valuable lessons about production AI and successfully optimized AI features without sacrificing quality through specific technical strategies.
