AISP in Customer Support Automation
A major financial institution deployed AISP to enhance their chatbot's ability to provide accurate and empathetic responses. By optimizing pre-logits at test-time, the chatbot achieved a 40% increase in customer satisfaction scores and a 25% reduction in escalation rates compared to their previous BoN-based system. This was achieved without retraining their base LLM, significantly reducing operational costs.
