# OpenCraft image examples — September 20, 2026

These images depict a fictional perfume product. They were generated through
OpenCraft's actual chat route using the opt-in `creative-image-examples` case
in `web/evals/cases.mts`. The PNG downloads are the original returned bytes.
The webpage uses smaller WebP previews of those same images.

## Comparison — exact user prompt

Generate one image with Seedream and one with Nano Banana 2, using this exact same image prompt for both: A sculptural cobalt-blue glass perfume bottle on a pale limestone plinth, one sweeping stem of white orchids, soft morning light from the left, pale blue studio background, generous negative space, luxury editorial product photography, landscape 16:9, no text or logos. Save the Seedream result as perfume-seedream.png and the Nano Banana result as perfume-nano-banana.png. Tell me which model made each file.

## Edit — exact follow-up user prompt

Edit perfume-nano-banana.png using Nano Banana 2: change the blue glass bottle to amber glass and the background to warm ivory. Preserve the bottle shape, orchids, plinth, framing, and lighting. Save as perfume-amber.png.

## Recorded results

The actual harness passed both turns, including checks for two different
identified generation models and use of the original image as the edit source.
The filenames and webpage labels correspond to the models requested in the
prompt. Per-image model receipts were not retained after an export failure,
so the model-to-file mapping cannot be independently verified from these files.

- Comparison: 53.0 seconds, 17,917 chat tokens, $0.1052 recorded turn cost.
- Edit: 46.8 seconds, 21,728 chat tokens, $0.0705 recorded turn cost.
- The runner reported $0.1758 total, rounded from the underlying usage.

These are complete turn costs including orchestration, not individual image
prices. Prices and timings describe this one run and are not a quote or speed
guarantee. The exact user requests are above; OpenCraft may expand a user brief
before passing it to an image model. No per-image price or exact provider
version is inferred from the rounded turn costs.

## Observations

The outputs have different bottle geometry and placement. The first added an
"AI generated" mark. The requested 16:9 format produced 1344 × 768 and
1376 × 768 images respectively, so crop or resize for an exact delivery ratio.
The amber edit preserves the broad composition and changes the bottle and
background colors. Review small details before using any result for a real brand.
