Your prompt

Create a 16:9 teaser image for the upcoming launch of a new smart thermostat with a circular glass display by a modern home-tech company. Concept: show only a glowing edge and a fragment of the circular display of the product, so the viewer is curious but cannot see the whole thing. Use deep shadow and a thin beam of cool light to partially conceal it. Atmosphere: mysterious, premium and quiet, dramatic contrast between light and shadow, a single strong light source from the upper right. Composition: product silhouette or detail in the centre-right, generous dark space on the left for a date or tagline to be added later. Colour: charcoal black with a cool cyan highlight. Constraints: no text, no logos, no full product view, no UI elements.

Example of what to expect

Illustrative only. It describes the kind of result this prompt aims for; real output varies by tool, model and run.

A dark 16:9 teaser: a fragment of a glowing circular display catches a thin cyan beam at centre-right, with empty dark space at the left for a date.

Expected format: One image; add the date and tagline in an editor.

How to use it

  1. Pair with a launch-date line you add yourself.
  2. Make 2-3 teasers with different reveal levels for a countdown series.
  3. Keep the real product's key design cue visible.

Limitations

  • Implied features or claims in a teaser still need to be true; the image should not suggest functions the product lacks.
  • Cinematic lighting can mislead about product colour; check the real item.

Platform notes

OpenAI GPT Image

Official docs read · checked 2026-10-11

Aspect ratio is set with the size parameter, not in prose. Use medium or high quality for text and fine detail.

General notes on OpenAI GPT Image
  • OpenAI's guide covers gpt-image-2 (recommended), gpt-image-1.5, gpt-image-1 and gpt-image-1-mini.
  • Aspect ratio is set through the size parameter, not in prose. Quality is low, medium or high; medium or high is advised for small or dense text.
  • Put literal text in quotation marks, and when editing say what must stay unchanged.

FLUX (Black Forest Labs)

FLUX.2 does not use negative prompts, so constraints are phrased as things to do.

General notes on FLUX (Black Forest Labs)
  • BFL's official guidance for FLUX.2: no negative prompts (describe what you want), write sentences rather than keyword lists, specify lighting, quote text to render, and pair colour names with hex codes.

Midjourney

Not verified: third-party guidance only · checked 2026-10-11

Append parameters after the prompt (e.g. --ar 16:9). Parameters vary by model version; verify in Midjourney's current docs.

General notes on Midjourney
  • Parameters go at the end of the prompt (for example --ar for aspect ratio). Parameter names and ranges vary by model version.
  • We could not read Midjourney's official parameter list on the verification date, so check the live docs for your model version before relying on any parameter shown here.

General notes on Any image generator
  • Written as natural-language descriptions that the verified image models accept. Syntax for aspect ratio, quality and negative prompts differs by tool, so set those in your tool's own controls.
