slugvision

~32,000 image → URL-slug pairs for training small vision-language models to generate 3–5 word kebab-case permalink slugs, e.g. three-brown-teddy-bears, nursing-workforce-growth-scaling. Built as the distillation corpus for slugvision-500m and slugvision-2.2b.

The distribution mimics editorial-site image uploads (article cards): a mix of everyday photos, conceptual editorial illustrations, product shots, clinical stock imagery, and web-page screenshots. All slugs were authored by a locally hosted Gemma-family teacher (26B-class); roughly half the corpus pairs each image with the article headline it was generated for, which trains a titled mode where the slug reflects the article topic rather than just the visible content.

Slices

Slice	Images	Labels file	Images included?	Title mode
photo	20,000	photo/slugs_photos.jsonl	No — COCO train2017 (see below)	untitled
illustration	5,000	illustration/slugs_illustrations.jsonl	Yes (FLUX.1-schnell renders)	titled
product	2,500	product/slugs_products.jsonl	Yes (FLUX.1-schnell renders)	untitled
clinical	2,500	clinical/slugs_clinical.jsonl	Yes (FLUX.1-schnell renders)	half titled / half untitled
screenshot	2,000	screenshot/slugs_screenshots.jsonl	Yes (rendered from bundled HTML)	titled

COCO images are not redistributed — they are Flickr-sourced with mixed per-image licenses. photo/slugs_photos.jsonl keys each slug by its COCO train2017 filename (e.g. 000000000776.jpg); download the images from cocodataset.org and join on filename. Every other slice's images were generated for this dataset and ship here.

Layout

photo/slugs_photos.jsonl            labels keyed by COCO filename
illustration/
  slugs_illustrations.jsonl         labels (+ generation headline as title)
  illustration_prompts.jsonl        teacher-authored FLUX prompts (headline, scene, style)
  images/illus-NNNNNN.jpg           5,000 renders
product/   (same shape: labels, prompts, images/prod-NNNNNN.jpg)
clinical/
  ... labels, prompts, images/clin-NNNNNN.jpg
  clinical_titles_half.jsonl        which images were labeled with a title
screenshot/
  slugs_screenshots.jsonl           labels (page headline as title)
  screenshot_prompts.jsonl          page index (id, topic, headline)
  pages/shot-NNNNNN.html            2,000 teacher-authored self-contained pages
  images/shot-NNNNNN.jpg            rendered screenshots (varied viewports)
train.jsonl                         the exact 30,739-pair training split
eval.jsonl                          the frozen 1,000-image eval split (200/slice)

Label record shape:

{"image": "illus-000014.jpg", "slug": "iron-absorption-mechanism-process",
 "raw": "iron-absorption-mechanism-process",
 "title": "How Iron Absorption Works in the Human Body", "valid": true}

slug is the normalized label (lowercase kebab-case); raw is the teacher's verbatim reply; valid flags 3–5 word format compliance (97.7–99.8% per slice). title: null means the untitled prompt mode. train.jsonl / eval.jsonl records use repo-relative image paths plus a slice field — photo-slice paths point at COCO filenames you must supply yourself.

Generation pipeline

1. Prompts/pages: the teacher authored FLUX prompts (headline + scene + style) for illustrations, products, and clinical imagery, and complete self-contained HTML pages for screenshots.
2. Images: FLUX.1-schnell (4 steps) rendered the three generated slices; Playwright/Chromium screenshotted the HTML at weighted random viewports.
3. Labels: the teacher labeled every image — with the source headline in context for titled slices, image-only otherwise.

All generation, training, and eval scripts live in the project repo: github.com/kelnei/slugvision.
