Neither DALLE version 1 or 2 was completely released. Further, DALLE2 definitely still has issues with generation of text, although latent diffusion can do an okay job of it.
It’s Imagen that can competently generate text, and their ablation studies show it gains the ability at a size somewhat above DALLE2’s, IIRC.

It still has issues of course, but a lot better at spelling than DALLE2.
