Communication with Google CoLab for Stable Diffusion?

Hi all - somewhat new to TouchDesigner/coding still, but am trying to build a free-to-use Stable Diffusion generator in TouchDesigner for a project. I know there are plenty of ways to get it working with an API from StabilityAI/other sources, but I’m really trying to have something I don’t need to pay for.
I’ve got a relatively simple pipeline built in Colab using StreamDiffusion and RunwayML, and I’m wondering if there’s a way to pull that into TD/have TD call on that from Colab? I don’t currently have a machine capable of really running it fully locally, so I’m pretty dependent on colab, sadly. Is there any way to do this?
Also, still pretty new to this stuff, so can clarify if needed/apologies if I’m explaining something incorrectly!
