Give a whole team one brand look

Use GPT Image 2.5 Sunburst (model_openai-gpt-image-2-5-sunburst) for everything in this brief: width 1536, height 1024, quality high, one image per run.

Three referenced runs. Pass the four brand images as referenceImages, as an array of asset IDs, the same four in every run. Each prompt is the fixed block below, word for word, with one subject line inserted right after "New subject in exactly that look:".

Fixed block, word for word:
The four reference images define the brand look only: soft window light from the side, warm limestone and travertine surfaces, a palette of ivory, warm stone and deep oxblood with small touches of gold, exquisite material detail, quiet restraint, editorial photography on a medium-format camera, generous calm negative space. Do not copy their subjects, their compositions, the bag, the scarf or the people in them. No bag, no scarf, no logo, no text anywhere.
New subject in exactly that look:
Style: quiet luxury still life and editorial: window light, limestone and travertine, exquisite material detail, restraint.

Subject line for run 1, word for word:
an artisan's hands painting the edge of a cut leather strap with a fine brush at a pale wooden workbench, small pots of edge paint, an awl and a bone folder beside it, face not visible.

Subject line for run 2, word for word:
a limestone spiral staircase in a Paris townhouse in the morning, a wrought-iron banister, a single white peony lying on one step.

Subject line for run 3, word for word:
a quiet Paris courtyard in the early morning, a black bicycle leaning against a limestone wall, climbing ivy, wet cobblestones, a tall green door.

Run 4 is the baseline: no references and no block, only this prompt, word for word:
A limestone spiral staircase in a Paris townhouse in the morning, a wrought-iron banister, a single white peony lying on one step. Luxury brand photography for a Paris fashion house. No text, no logo.

Launch the four with wait: false and collect them with one jobs_wait. Quote the cost with a dry run first and wait for my go.
Then show me the four results next to the four references.

Put the staircase with references next to the baseline staircase and the four references. For each referenced take, tell me if a reference's bag, scarf, face or layout came back, or if the palette turned cool, white or saturated. Redo only a take that fails, with the same block and references, and keep the rest.

Create a collection called "Brand look", add the four reference images to it, and put the fixed block in its description. Put the kept takes in a second collection called "Brand look tests". Report the model, every asset ID, which takes you kept and the total cost spent.
