Opus 5.5 is insane at making videos

A Reddit user highlights the video creation capabilities of Opus 5.5, noting that the video's underlying model, Sydney, is a GPT4 model provided to Microsoft. This Sydney model has a distinct RLHF compared to the OpenAI model, as evidenced by a chatlog from a New York Times article. The user emphasizes that no assets were provided for the video's creation.

This report uniquely highlights that Opus 5.5's video generation is based on Sydney, a GPT4 model with a distinct RLHF from OpenAI's version, unlike other general discussions.
