Aurora Research Cabin

STARTING PROMPT

Reusable prompt

The original English prompt is kept unchanged so you can reproduce the Aurora Research Cabin example.

Original English prompt

A cinematic architecture photograph: a compact cobalt-blue research cabin with a seamless unmarked metal exterior on a frozen lake at blue hour, warm amber windows, pale green aurora reflected in the ice, a single tracked snow vehicle nearby for scale, crisp realistic materials and quiet polar atmosphere. The cabin facade and door are completely plain and blank with no signage, house number, letters, digits, symbols, or markings.

What we saw when we re-ran it

On 2026-10-27 we re-ran the Aurora Research Cabin prompt twice on Nano Banana 2 (gemini-3.1-flash-image) at 1:1 and 1K through POST /v1/media/tasks. Each task finished in about 18 seconds end to end, with the status polled every 5 seconds.

  • Both runs kept the cobalt-blue cabin on a frozen lake, amber windows, green aurora, snowy mountains behind and one tracked snow vehicle, as did the gallery cover.
  • Neither run put signage, numbers or letters on the door or facade: the closing no-markings sentence held both times.
  • "Seamless" did not hold: both cabins show vertical panel joints like a modular container. One run added a metal stair with a railing; the other a skid base with a small lantern.
  • The ice mostly reflected the amber windows. The green aurora reflection the prompt asks for was weak in both runs.
  • The snow vehicle changed colour between runs (dark in one, orange-red in the other); the prompt does not name a colour.

Make it yours

  1. 01

    Describe the finish you want

    Both runs showed vertical panel joints, so "seamless" alone did not hold. If the shell must read as one piece, describe it, for example "a single smooth cobalt shell with rounded corners and no visible panel joints". If joints are fine, drop "seamless" so the prompt matches the image you get.

  2. 02

    Name the vehicle colour

    Add a colour after "tracked snow vehicle", for example "a tracked snow vehicle in matte orange-red", and repeat it if the shot must match an earlier frame. The two runs returned dark and orange-red vehicles, so an unnamed colour leaves the choice to the model.

  3. 03

    Strengthen the ice reflection

    Describe the reflection as its own element, for example "pale green aurora mirrored in the black ice in the foreground", so it competes with the amber windows. Both runs gave a weak green reflection while the ice mostly mirrored the windows.

Check before you rely on it

  • The id gemini-3.1-flash-image was deprecated on 6 October 2026 with no shutdown date, so new work belongs on gemini-nano-banana-2.1 while this id keeps answering. Copy whichever id you use exactly.
  • Lettering can appear even when a prompt forbids it: in our Nano Banana 2 tests a pottery scene that asked for no text still showed SHIMPO on the wheel. Check the door and facade for stray marks before delivery.
  • Budget for variety between runs. The vehicle colour and the details around the base changed, so ask for more than one image when the frame has to match an existing shot.

Questions

Did the no-markings sentence work on the cabin?

Yes. Neither of the two runs on 2026-10-27 put signage, a house number, letters or symbols on the door or facade, so the closing sentence did its job both times. The model does add lettering in other scenes, so inspect each image before it ships.

How do I run this template through the API?

Send POST /v1/media/tasks with the Nano Banana 2 id gemini-3.1-flash-image, the prompt, and the two settings as request parameters: aspect_ratio 1:1 and image_size 1K. Poll the task until it succeeds, then read assets[].url. Billing is per generation, at the starting price listed under Template details.

Can I use a wider aspect ratio for this cabin?

Yes. Nano Banana 2 accepts aspect_ratio auto or a listed ratio, and image_size 1K, 2K or 4K, so a wide frame gives the lake and the mountains more room than the square cover does. The 1:1 preview is the gallery default rather than a limit of the model.
