Tech Graphics Benchmark: annotations
Write-up: Can image models spell the labels? A first look at my Tech Graphics Benchmark
Raw human evaluation data for Tech-Graphics-Benchmark: one JSON file per annotated generation, written by the annotation Space. The model was hidden from the annotator until the file was saved; cost and size were shown.
- Prompts: danielrosehill/Tech-Graphics-Benchmark
- Generations (images + manifests): danielrosehill/Tech-Graphics-Benchmark-Runs
Layout: annotations/<run_id>/<gen_id>.json. gen_id matches a row in the runs dataset's <run_id>/manifest.jsonl.
| Field | Type | Meaning |
|---|---|---|
run_id, gen_id, prompt_id, model |
string | Which generation |
usd_per_image |
number | List price of the generation (USD) |
width, height |
int | Delivered image size in pixels |
text_exact |
bool or null | Every expected string present and spelled exactly; no invented text |
text_legible |
bool or null | All text readable at a glance |
structure_ok |
bool or null | Arrow, order and placement instructions honoured |
meaning_preserved |
bool or null | Same meaning as the brief or the original sketch |
rating_style, rating_overall, rating_value |
int 1–10 or null | Style, would-publish, value for money |
text_errors |
string | One error per line, expected → got |
notes |
string | Free-text comments |
process_notes |
string | Notes about the annotation process, not the image: criteria to add or change, things the form couldn't capture. Absent before 2026-10-28 |
annotated_at |
ISO 8601 UTC | When saved |
A validation field is null when it doesn't apply to the prompt (see the prompt's validation list): not applicable, not a fail. Annotations saved before 2026-10-28 20:45 UTC have every tick as a bool.
process-notes/<YYYYMMDDTHHMMSS>.json holds process notes saved without an annotation: {note, run_id, gen_id, prompt_id, written_at}, the generation being the one on screen when it was written.
Annotations saved before 2026-10-28's form change may lack text_legible, width and height. Grading and scoring: README § Grading.
