Free Tier Arrives in Comfy Cloud, with a simple no-fuss Google login/signup. 400 credits a month, no roll-over. Apparently that gets you about 20 minutes worth of generation on a fast GPU. Enough to try the latest ‘hot new’ model each month, maybe even a couple of times, and see if it’s for you or not. Or perhaps very slowly generate a short film, a bit each month. There are no free workflows/models, everything consumes credits.
Alongside the usual it offers tools useful for the 3D crowd, such as ‘sketch to 3D model’, or relighting of a rendered scene without re-rendering.
