Claude Sonnet 5 itself described its pelican as looking like a goose:

That's possibly the worst pelican I saw from all recent LLMs.

Meanwhile GLM 5.2 drew a cool self-contained fully animated SVG pelican:

Yeah, GLM have been beating Anthropic on the pelicans for a while now.

(I suspect that's more of an indication that Anthropic have chosen not to waste resources training on animals riding vehicles, personally.)

		That's one possibility albeit quite charitable. I'd be inclined to think the same personally if GLM 5.2 wasn't also rocking in other areas too.
