Challenges in Building Safe
LLM-Powered Conversational Systems
Developing safe conversational systems powered by Large Language Models (LLMs) presents distinct challenges. This presentation focuses on the need to ensure dialogues stay on-topic, guarantee user safety, and maintain system security. We will touch on reducing model hallucinations, ensuring rigorous fact-checking, input/output moderation techniques, and strategies to deal with sensitive data. Additionally, we will briefly explore the intricacies of safety in multi-turn conversations. Finally, we will introduce the NeMo Guardrails toolkit by NVIDIA for building safer conversational systems.
