EthnicErotic is a catalog of the world's peoples with a phenotype layer measured by a vision model against controlled vocabularies, an erotic pose catalog built from keypoint geometry, a comparison layer for text-to-image generators, and a reader feedback loop that decides which portraits the site shows. This log explains how each part works.
This is a running log of what we build on EthnicErotic and how it works. The site is a reference catalog of the world's peoples, and it runs on pipelines: candidates harvested from open knowledge bases, profiles written from encyclopedic sources in many languages, features measured by a vision model against controlled vocabularies, positions stored as keypoint geometry, and portraits judged by readers.
Start with the systems, which lay out the machinery: what each one does, the stages it runs in order, and a figure that measures it. The dated log follows, newest first, recording each build with the technical detail behind it.
The systems
Seven systems carry the site, from the pipeline that authors new peoples to the loop that lets readers replace a portrait. Each card lists its stages in order and one figure that measures it.
New peoples enter the catalog as candidates harvested from Wikidata and leave as full profile pages. Each candidate is screened against a written rubric that separates peoples from governments, census categories and list pages. A language model then writes the profile in US English from the best available Wikipedia language edition, from French to Russian to Indonesian. Before a page publishes, it is matched to its own Wikipedia article, one article to one page. Pages publish in waves ordered by documentation depth, so the best-documented peoples go first.
Twenty-two controlled vocabularies define 196 dimensions of the face and body, each anchored to a published scale such as the Fitzpatrick skin types, and the analysis prompt, data schema, aggregation and documentation are all generated from those vocabulary files. A vision model reads real reference photographs against the dimensions a photograph can show, and a deterministic aggregator with no language model in the loop turns the readings into per-people distributions with sample sizes. A test-retest reliability study, scored with Cohen's kappa, is written back into the head and neck vocabulary files it measured.
Portraits live in per-people galleries rather than as a single picture. Each portrait prompt is built on one of four style registers, traditional, modern diaspora, modern urban or mixed, so heritage peoples appear in traditional dress and modern diaspora identities in contemporary clothes. A language model drafts the prompt from that people's homeland, phenotype profile and register, and each render from the pipeline records how it was made. Every render joins the gallery as a candidate, and readers' votes choose which portrait leads the page.
Each of the 219 positions is structured data: a 17-point keypoint template for every participant, composed deterministically from shared base-posture skeletons and a placement transform. The site draws every figure straight from those keypoints as a shaded articulated mannequin, with no image generation, and layers separate vocabularies of actions, camera moves and context on top. Positions link to their sources in historical manuals, from the Kama Sutra to the Perfumed Garden, and to museum-attested art, and a crosswalk maps them to outside vocabularies.
The people is held constant and the generator varies: six text-to-image generators draw the same people from the same prompt, and the same vision model that built the real-photo baselines reads every render. Wherever a people has a real-photo baseline, renders are scored against it, and readers vote blind on pairs, with generator names hidden until the vote. Nothing ranks peoples, and when a generator misses a people, the miss is recorded as that generator's result.
Under the catalog's portraits sits a one-tap question: does this look right? No account is needed to answer it. A "Looks off" tap opens reason chips for skin tone, face, hair or setting, an inline deck deals up to five portraits without leaving the page, and verdicts are published as open data with the surface each was cast on. When a majority of readers say a portrait looks off, new candidates are rendered, the flagged portrait is replaced, and the page says so.
The catalog's foundations are published as open research. Two datasets on Hugging Face carry the peoples, the vocabularies, notable people, image observations, reader verdicts, generator comparisons and the pose catalog under CC BY 4.0, and both pipelines are public under Apache 2.0 with methodology papers. Each pipeline has a concept DOI on Zenodo, so the work can be cited and rebuilt.
The log
Each peoples page shows eight related groups. Until today the same few hundred pages filled nearly every block; now the links are spread across all 4,076, and 53 pages are left without an inbound link instead of 3,323.

The two prose sections of a peoples page now read in three more languages for more than 800 of the peoples readers look up most, written by a machine pass and screened one text at a time before any of it went on a page.

Two more languages join the site: the 219 positions, the six pose reference pages, the 31 atlas pages and the home page now read in Portuguese and Russian under their own addresses.

The generator comparison layer now renders the same peoples through six text-to-image generators, scores every render against the catalog's phenotype profile, and gives readers the pairs to judge.
115 positions join the crosswalk that maps each named position into the tag vocabularies image models were trained on, with a written statement of what each mapping loses. The open dataset carries the whole set.

Every section of the site, the peoples pages included, now has French, German and Spanish twins with translated addresses, and each page lists its alternates in the other languages.
When a majority of readers say a portrait looks off, the site renders replacements, promotes one and says why on the page. Twenty faces changed in a day.
