Geotab has revolutionized fleet management by leveraging generative AI with its cutting-edge agent, Ace. The agent uses a retrieval-augmented generation (RAG) architecture to retrieve domain-specific knowledge dynamically, ensuring accurate and context-aware responses. With the integration of Arize AI for observability and evaluation, the system continually improves while maintaining reliability and trust. Geotab's vast telematics platform generates immense amounts of data, spanning 200 tables and billions of rows, making it challenging for users to derive insights effectively. The agent addresses complexity, time-intensive querying, high error rates, and opaque workflows by providing actionable insights with seconds. The system delivered drastic efficiency gains, reduced query times from hours to seconds, and empowered fleet managers to make smarter decisions faster.
