How to Moderate Live Chat in Real Time with Jev and Composio (Discord + Twitch)

Moderating live chats on platforms like Discord and Twitch is a significant challenge due to the speed of incoming messages. Traditional LLMs are often too slow and expensive for simple binary moderation decisions. This article explores using Jev, a specialized decision model from TypeSafe, integrated via the Composio toolkit. Unlike generative AI, Jev provides probabilistic scores for specific questions, making it ideal for high-speed moderation. The author demonstrates how to build a unified moderation logic that evaluates messages for hostility or harassment and triggers automatic deletions or human review. By utilizing Node.js and EventSub, the solution maintains low latency and minimal costs, processing messages for a fraction of a cent. The project, available on GitHub, offers a practical template for developers looking to automate chat safety without the overhead of full-scale language models.
