Pelicans for thinking levels low, medium, high, and xhigh:

max is in there too, but it ran out of reasoning tokens (128,000 limit) before it got to the actual SVG.

Scored only a 77/100 in PacBench, which I thought must have been a mistake.

Then I clicked on it and realized it refused to make a Pac-Man game, and instead made up a new game. That's actually very slick.

Before everyone jumps in the benchmaxxing comments, I genuinely find the pelicans a great bit of fun and whimsy amongst the chaos.

Interesting how low detail these were all up until xhigh.

I haven’t read any of the other model reasoning traces, but do many others now say “… which is a well known test of drawing ability” when beginning? Noticed it in the max reasoning trace.

I added a second iteration with the simple prompt

"Make it more realistic"

Well, the result is something. Be aware that it took 20 minutes and used 3 percent of my weekly Fable token (Ultra plan):

Simon has there been other times where the front and rear wheels have been offset in rotation? The xhigh effort one is the first I’ve noticed of this

So the AI can overthink too

The fidelity of these pelicans is going to be based on whether the frontierlab has an RL setup specifically for making SVG images, lol

I know the latest Gemini release explicitly had something like this.

Seems like the higher levels just add more spontaneous detail. Like the "fingers" on xhigh. Comports with coding experience.

In practice why would anyone use fable low?

It's a bit underwhelming, to be honest. And the fact that curves are not C-continuous where they obviously should be is disappointing. I think they are holding back with the real capability they could implement.
