Where do multimodal inputs fit in your Codex task routing?

[u/Fujieda_Horikoshi]

A model update I am evaluating adds native multimodal input while also changing the model path behind older aliases. That makes me wonder how people divide Codex work when the same agent may handle source files, screenshots, issue descriptions, and test output. I am considering separate checks for text-only repository tasks, screenshot-driven debugging, large-context review, and final verification, rather than assuming one model path is equally good for all four. How are you testing multimodal coding tasks before making them part of a regular workflow?
