About NeutronField: this domain's history, who writes here, how we test

Prompt guides for the generators people use now, and what each one writes into the finished image.

Each prompt guide covers one generator or one technique: how the model reads a prompt, the settings that change the result, and worked examples we ran ourselves. Each Made with AI page covers what that generator puts into the file it hands back: a signed content credential, an invisible watermark, metadata fields, or the prompt itself.

It is written for people who make images with these tools: designers building mood boards, hobbyists running open models at home, marketers working in a chat assistant, illustrators using generative fill. Nothing here is for sale, there are no accounts, and we do not take submissions.

From 2023 to 2024 this domain hosted the NeutronField prompt marketplace, which closed in 2024. This site is a new publication and is not affiliated with it.

Archived captures show the domain was registered in 2020 and held a placeholder page, then a small merch shop in early 2022. From January 2023 the name belonged to a marketplace where members posted text-to-image prompts with example images and sold them, sorted by model and by theme. In May 2024 the marketplace was replaced by a notice that it had closed. The domain later lapsed and was registered again in 2026.

We kept the name because the old site was about image prompts too. We did not keep its listings, member pages or accounts: those addresses now say the page is gone. If you bought a prompt there, this site has no record of it and no way to reach the former team.

What happened to prompt marketplaces

The editors write, run and check every page. A page shows the date it was last updated, and when a model version changes what a prompt does, we rerun it and change the date rather than leave an old result standing.

If you find a mistake, write to editors@neutronfield.com with the page address and what is wrong. We correct the page and note the change in its update date.

• How prompts are run

  We run every prompt we publish ourselves, on the model named beside it, and record the model, version, date and settings, including the seed where the tool exposes one. We show the frames a run produced and mark the one we kept, so you can see what a prompt does on an ordinary attempt, not only its best one.

• How files are read

  We read each file exactly as the generator handed it over, before any resizing or conversion. Content credentials are read and validated with the open-source C2PA library (c2pa-rs); EXIF, XMP, IPTC and PNG text chunks are read segment by segment. An invisible watermark is marked present only when the vendor's own detector, or the vendor's signed record in the file, says so; otherwise we leave that record out of the page.

• Sources policy

  Every claim about a generator is checked against that vendor's own documentation as well as a file we made, and the page links the source and says when we checked it. For how models work we cite the original research papers. We do not treat third-party AI detectors as evidence.
