A company developed an LLM layer to improve customer service interactions, starting with a bot for routine reminders and evolving to incorporate a language model that understands response context. This system, featuring a cascade of two judges and an arbiter, increased action alignment with annotations from 74% to 84% and reduced overall errors by 38% while maintaining similar costs. The team achieved this by refining prompts, rules, context length, and comparing models, noting that an additional process feature proved more impactful than some model experiments. AI
