Summary

Mux has launched a Robots Playground in its dashboard that lets users test AI video workflows such as asset summarization, key-moment detection, caption translation, premium caption generation, and content moderation before integrating them through the API. Users can select a video asset, configure workflow parameters and output steering, view formatted results alongside the video, and compare multiple runs to assess how settings affect outputs. The playground turns raw JSON into interactive elements including clickable chapters, key-moment cards, transcript cues, thumbnails, and tools for creating instant clips, while allowing speaker-label corrections to update caption tracks directly. Each playground job uses the live Robots API, is retained in the jobs list for 30 days, and incurs the same unit costs as API-created jobs. Once settings are finalized, users can copy an agent prompt containing the endpoint, parameters, webhook, and output-handling guidance to help move the workflow into production, while a session-level cost display tracks usage in units and dollars.
