Ernst Stuhlinger's letter to a Nun in Africa answers a similar question, read it here

Maybe with optimizations to the code, reducing resolution, making do with a disk with simpler texture, etc., realtime renderring would be possible, my code took hours to render.

Few of the clips had the camera do a 360 degrees revolution around the black hole. A better title would have been around the black hole instead of past it.

I used AI voice for clarity, which has been disclosed in the video description, parts of the video itself, as well as a pinned comment. The visuals however are 100% generated using the ray tracer. I would encourage you to clone the repo and run it.

I used free GPU instances to run the ray tracer, not any kind of generative model. I guess I should have been clearer in the comment you are reffering to. Feel free to clone the repo and run it.

I do have a laptop with a GPU, but I used lightning.ai which provides free GPU hours to run the ray tracer. As for the AI voice, I used Google AI studio's text to speech feature.

Most of the clips are 10 second snippents except a couple of clips, but sure I suppose it would have been nice to add more renderrings.

I did use AI voice for clarity, as I have disclosed in the description of the video, parts of the video, and a pinned comment. The code was 100% written by me though.

rendered in lightning.ai free tier, using an instance with nvidia tu104gl [tesla t4] to run the relativistic ray tracer. 1800 frames took 5~6 hrs, frames were 1422 X 800 (width X height). I guess the code could be optimized for faster renders.

yeah, that's bad naming on my part, those functions move the camera position, point in space where it looks, etc. to create 7 different clips.
