ChatGPT Is Still Not Very Good With Sketching

I gave this prompt to ChatGPT:

Sketch an object moving in a circular path, showing the tangential velocity at 4 different points along its path.

This was the image that it gave me:

 

I then gave what I thought a simpler prompt:

sketch an object moving in a circular path having a centripetal force

... and this was what I got:

 

 

I guess it is worth a giggle.

I have a paid version of ChatGPT for work so I gave this a whirl. Mine was better than yours but was still wrong. When I told it that it was wrong and asked it to explain, it correctly explained the errors. It offered to redraw, and that one seems right, at least if you allow a little artistic license for the circle not actually being circular. Which, hey, I can't draw circles either.

I think that if I were to pay for such a service, I'd pay for Gemini because on average, it seems to produce more accurate images. However, they have recently moved that feature behind a paywall.

Yeah, image generation is surprisingly poor, given that image search is not bad. My classic example of this is asking your favorite image generation tool to draw a benzene molecule with the six carbon atoms shown as black spheres and the six hydrogen atoms shown as red spheres. The paid (university-provided) versions of copilot and gemini can now do this. Six months ago both would have failed.
