Impressive that videos generate so quickly
From 3 comments
Well, I'm blown away. "Show me how information propagates through a neural net." I feel like this is the one thing that's been missing from all the LLMs: actual visual…
tunesmith on HNWow, this is awesome! Thanks for building. I didn't realize there was a protocol for streaming while rendering, though I noticed sumo.ai doing something similar for audio. Gemini…
cr4zy on HNThis is so cool! Streaming videos while the Manim code is still generating is super impressive - sure that took a lot of hacking.

Content is superficial and often wrong or misleading
From 3 comments
As usual with these things: it is impressive that stuff like this can be generated so quickly at all, but the content is very superficial and often wrong or at least misleading.…
deng on HNGreat but wrong answers. I asked how big tree-3 was after some helpful explaining about exponentials, it tells me its 27. This is... an underestimate.
Eddy_Viscosity2 on HNIt will happily explain non existing concepts as well: https://tma.live/video/26c9fec7-3bb7-42e5-837f-617fd5659f70

Visual layout problems and overlapping text
From 3 comments
The Manim is not great, words overlapping etc, the page itself needs a lot of work, generating and then nothing happens, and it seems in a lot of case your backend workflows have…
cchance on HNHaha that’s funny, the beehive one lays out the hexagons as if they were squares - so they overlap and have empty space lol! But still it’s a promising concept. Btw for some…

Frequent failures, rate limits and generations that stop early

AndrewKemendo on HNWhether I click an existing example or type in my own it doesn't seem to work. A dialog pops up for a second saying 'generating video' and then disappears.
neumann on HNWell, it wasn't wrong at least, it just... stopped about 1% into the explanation.

Far below 3Blue1Brown quality
From 2 comments
Those videos are apex quality videos. You might as well ask for Nobel prize literature quality essays from ChatGPT. You can probably imitate the structure/scaffolding of a 3b1b…

deng on HNI'm not really a bear on llms, but using it for explanations in this way needs a lot of caution. It's very easy to give an argument that "seems" right at first glance, e.g.…

How long did it take to build

Can I ask from curiosity how long it took you to program and design this entire project?

MathGPT also has this (exactly in the same 3blue1brown style, so I guess they also use manim), and in my experience it does actually work better and tries to explain math and…
