An SFU routes many live streams efficiently without re-encoding them all, which makes group calls scale. Because every stream passes through it, the SFU is the place to run server-side AI once for everyone — shared captions, moderation, recording.

AI for Video: A Complete Guide to Intelligence in Video Products: From Real-Time Pipelines and Agents to Serving, Cost, Compliance, and Verticals
An SFU is where every stream of a group call already passes, so it is the cheapest place to run captions, moderation or recording once for everyone. Volume 7 covers the SFU in detail as the AI insertion point: call latency budgets, where AI plugs into a WebRTC pipeline, live captions and translation and on-the-fly moderation. Written by Nikolay Sapunov, CEO at Fora Soft.
