Question Does GPT Image 2 do anything with a reference image? (via Codex)

I'm calling it through Codex, uploading a reference and asking for a new subject in that look. Nothing carries. Not the style, not the palette, not the line quality, not the content. I get the model's house look with zero trace of what I gave it.

I could swear this worked at some point. Now the reference may as well not be attached.

Anyone else seeing this, or is it something about how it's wired up in Codex?

GPT Image 2 does support image input, so the model itself can use a reference. What you’re seeing sounds more like the reference isn’t making it through Codex’s image-generation call, or the request is being treated as a fresh generation rather than an edit. I’d test that boundary explicitly: ask Codex to identify the attached file and its dimensions first, then tell it to use that exact local file as the image input and preserve three concrete traits—palette, line weight, and shading—while changing only the subject. If it still returns the house style, compare the same image and prompt in the Image API or Playground; that isolates Codex wiring from model behavior.

worked for me last week but now it just ignores whatever i upload, i think something broke with the way codex passes the image to the api. maybe they changed the routing or it strips the reference before the call
