Oh Clip-guided Diffusion ... did you succeed to get some results under a free Colab ? If yes i would be interested to know which notebook you found, because basically under a free Colab, i have to wait hours and hours to get a 256*256 size picture (usually i get a K80 with 12Gb GPU...). I wonder if there are some optimized notebook that would require less resources to play with Guided diffusion, because the produced pictures looked quite more polished and detailed than VQGAN. So far i did not find.
