Hey! I made a minimal CustomTkinter app for captioning many images through LM Studio's local OpenAI-compatible server to create training datasets for text-to-image models such as Flux, Qwen, Z-Image, Ernie Image, etc..
Each image is sent as a separate request, so context does not accumulate across the batch.
Easy install!
The idea came from testing Gemma 4 and its vision capabilities for images inside LM Studio chat. I really liked the results!
You can use any model you have installed in LM Studio, as long as it supports Vision.
