What variant of Codex are you using?

Codex App

What feature would you like to see?

Add a node-based / graph-based workflow surface for image generation in Codex App.

The current chat flow is useful for quick one-off image generations, but image work often becomes iterative and branchy:

  • generate several options from a prompt
  • choose one image as a source
  • make variations
  • upscale or crop
  • edit a region
  • combine reference images
  • compare branches
  • preserve prompt/settings lineage
  • move selected outputs into a project

A lightweight node workflow would make this much easier to manage. This does not need to be a full ComfyUI replacement, but a visual graph/canvas for generated-image workflows would fit the way users already think about iterative image production.

Useful node types could include:

  • prompt/image generation
  • image input / reference image
  • variation
  • edit/inpaint
  • crop/resize/upscale
  • background removal / transparent output
  • comparison/select node
  • export/save-to-workspace node

The important part is preserving the relationship between images, prompts, edits, and final exported assets. Chat history alone becomes hard to navigate once there are many generated images and variations.

Additional information

I searched existing open and closed issues for combinations of:

  • Imagen + node-based
  • image generation + node / graph / workflow / canvas
  • ComfyUI
  • visual workflow image generation
  • multi-step image generation

I found related image-generation requests, but not this specific node/graph workflow request:

This request is specifically about a node/graph workflow surface for iterative image generation, branching, comparison, and export.
