How do I determine what base model is used when calling the txt2img API route?

[monis24]

With the txt2img route, I understand that I can choose which controlnet model I'm using with the controlnet_model attribute, but where is it determined which base model (sdv1.5, my own trained model, etc.) is used?

The /controlnet/*2img routes inherit the code from the original /sdapi/v1/*2img routes. you can use the same mechanisms that are available under /sdapi/v1.

Note that as the webui has been updated to support alswayson scripts. We are currently working on updating the code to deprecate /controlnet/*2img routes.
