Summary

The creator shows their ComfyUI setup: custom LM Studio nodes create JSON prompts, which then feed Ideogram v4 running locally. It shows how to chain a local LLM into an image-generation pipeline.

Key points

• Custom LM Studio nodes inside ComfyUI generate JSON prompts.
• A local LLM served by LM Studio writes the structured prompts.
• Ideogram v4 runs locally in the same ComfyUI graph.
