Synthesia launches Syren Video: prompt-to-video agent powered by Opus 5.5, free to try

Synthesia's Syren Video is now live and free to try: prompt it to produce agency-quality AI video, then chat to refine the result. It's powered by Opus 5.5 plus the Syren renderer with 3D support, and works in the browser or via Claude MCP. The retweeter calls it a potential 'ChatGPT moment' for video if quality holds.
