Fastweb and Vodafone revolutionize customer service using AI agents, Super TOBi and Super Agent, leveraging LangGraph and LangSmith to improve customer interactions and call center operations.
Fastweb and Vodafone, subsidiaries of the Swisscom Group, have embarked on a transformative journey to enhance their customer service operations using advanced AI solutions. The companies, which serve millions of customers across Italy, have turned to AI to address the complexities and scale of telecommunications customer service.
Challenges in Traditional Customer Service
Traditional customer service models in telecommunications are challenged by the need for immediate and effective resolution of diverse customer queries, ranging from billing to technical support. Fastweb and Vodafone identified that their existing systems, while efficient, could benefit from AI-powered enhancements to handle nuanced and context-driven customer interactions.
Introducing AI Agents: Super TOBi and Super Agent
The introduction of AI agents Super TOBi and Super Agent marks a significant shift in how Fastweb and Vodafone manage customer interactions. Super TOBi, an evolution of the existing chatbot TOBi, operates at an enterprise scale, handling complex customer queries across various channels. It uses a graph-based decision-making process with LangGraph, ensuring consistent and efficient query handling.
Super Agent, on the other hand, is an internally facing AI tool designed to assist call center consultants. It provides instant diagnostics and guidance, enhancing the consultants' ability to resolve customer issues with a high degree of accuracy and compliance.
Leveraging LangGraph and LangSmith
Fastweb and Vodafone's AI transformation is built on LangGraph and LangSmith platforms. These tools enable the creation of intelligent customer interactions through a structured approach that mimics experienced customer service representatives. The Supervisor pattern within LangGraph ensures deterministic routing of customer queries, while specialized sub-graphs handle various use cases.
The integration of LangSmith allows for continuous monitoring and evaluation of AI performance, ensuring that the systems are always optimized for accuracy and efficiency. This observability is crucial for maintaining high service standards and quickly addressing any issues that arise.
Impact and Future Prospects
The deployment of Super TOBi and Super Agent has led to impressive business metrics, including a 90% correctness rate and an 82% resolution rate. These improvements translate into faster response times, reduced need for human operator intervention, and higher customer satisfaction scores.
Looking ahead, Fastweb and Vodafone plan to expand the capabilities of their AI agents, leveraging the success of their current implementations to explore new applications across their telecommunications operations. With a foundation built on flexible architecture and robust monitoring, they are well-positioned to continue innovating in the AI space.
