Botanical Machine
Translucent leaves, brass gears, and copper filaments combine in a speculative botanical machine.
STARTING PROMPT
Reusable prompt
The original English prompt is kept unchanged so you can reproduce the Botanical Machine example.
A detailed speculative illustration: a delicate botanical machine growing from a brass base, translucent leaves, tiny gears, dew and exposed copper filaments, pale laboratory backdrop, scientific plate composition rendered as premium 3D illustration.
What we saw when we re-ran it
On 2026-10-27 we re-ran the Botanical Machine 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 23 to 35 seconds end to end, with the status polled every 5 seconds.
- Both runs added printed text the prompt never asked for: a plate title ("Speculative Botanical Machine, Specimen-01A" in one, "Chlorofibra Mechanica, Specimen IV" in the other) and lettered or arrowed callouts. One run also drew a chalkboard and a small labelled chart.
- The gallery cover has no text. The phrase "scientific plate composition" reads like a request for an annotated plate.
- The brass base, translucent leaves, tiny gears, copper filaments and pale laboratory backdrop came through in both runs.
Make it yours
- 01
Replace plate wording
Swap "scientific plate composition" for "clean studio illustration on a plain background" and add "no labels, no captions and no arrows" at the end. Both runs treated the plate phrase as a request for annotations, so this wording controls whether the image arrives labelled.
- 02
Name the specimen title
If a caption is wanted, write the exact text, for example "a small label reading Brass Fern", and give it a place on the lower margin. Without a named caption the model invents a title and adds callouts of its own.
- 03
Set the backdrop
Change "pale laboratory backdrop" to a named paper, for example "off-white paper backdrop with a soft shadow beneath the machine", so the specimen sits on a defined sheet. One run added a chalkboard and a labelled chart, which this wording can push aside.
Check before you rely on it
- Lettering arrives uninvited here. Both runs printed a plate title and callouts, and in our Nano Banana 2 tests a pottery scene that asked for no text still showed SHIMPO on the wheel, so read every output before use.
- All runs used gemini-3.1-flash-image, which Google deprecated on 6 October 2026 without naming a shutdown date. OmniaKey lists Nano Banana 2.1 (gemini-nano-banana-2.1) as the newer id for a new botanical series.
- Invented wording is a habit of this model: in our Nano Banana 2 tests it added a line under each step of an infographic and got two of them wrong. If you keep callouts, proofread them before a client sees the plate.
Run it through the API
Built from the template's model id, prompt and settings. Set OMNIAKEY_API_KEY in your environment first.
curl --fail-with-body https://api.omniakey.com/v1/media/tasks \ -H "Authorization: Bearer $OMNIAKEY_API_KEY" \ -H "Content-Type: application/json" \ -H "Idempotency-Key: $(uuidgen)" \ -d '{ "model": "gemini-3.1-flash-image", "type": "image", "operation": "generate", "input": { "prompt": "A detailed speculative illustration: a delicate botanical machine growing from a brass base, translucent leaves, tiny gears, dew and exposed copper filaments, pale laboratory backdrop, scientific plate composition rendered as premium 3D illustration." }, "parameters": { "aspect_ratio": "1:1", "image_size": "1K" } }' # Then poll the task until its status is succeeded curl --fail-with-body https://api.omniakey.com/v1/media/tasks/<task-id> \ -H "Authorization: Bearer $OMNIAKEY_API_KEY"
Questions
Why did my botanical machine come back with labels?
Because "scientific plate composition" reads as a request for an annotated plate. Both runs on 2026-10-27 added a made-up plate title plus lettered or arrowed callouts. Ask for a plain background and no captions instead, then check the image, since this model adds text uninvited.
How do I run this prompt through the API?
Post the prompt to /v1/media/tasks with gemini-3.1-flash-image as the model and the settings as request parameters, aspect_ratio 1:1 and image_size 1K. Poll the returned task until the state is succeeded, then take assets[].url. Each generation is billed at the starting price shown under Template details.
Which parts of the prompt came through in both runs?
The brass base, translucent leaves, tiny gears, copper filaments and pale laboratory backdrop all appeared in both runs on 2026-10-27. What changed was the framing around them: plate titles, callouts, and in one run a chalkboard and a small chart. Keep the object clauses and edit the composition clause.
