Prompt
A 3D render of a glass terrarium in the shape of a geometric dome, inside the terrarium a miniature garden with tiny ferns, small white stones, a patch of moss, and a tiny winding path, the glass with subtle refraction showing the contents slightly distorted at the edges, soft internal lighting glowing from within the terrarium, the terrarium sitting on a simple wooden base, a dark background with a single soft spotlight on the terrarium, octane render quality, the glass material with realistic transparency and subtle surface imperfections, no people, no text, no letters, no watermarkHow to use this prompt
- 1
Open the generator that matches the model and version above, and start a new image rather than editing an existing one.
- 2
Set the output to 3:4. That is the only output setting recorded for this entry, and it is what produced the 576 × 768 image on this page.
- 3
Paste the prompt exactly as written. Changing the wording changes the image, so copy it before you edit.
- 4
Generate, then change one thing at a time. The result will not be pixel-identical to the image on this page, because no seed is recorded for it.
Only an aspect ratio is recorded for this entry. GPT Image and DALL·E do not expose a sampler, step count, or CFG value in the interface this was tested in, so there are no numbers to match — the prompt text and the aspect ratio are the whole instruction. Resize by describing the framing in words rather than reaching for a parameter.
