| # Tech Graphics Benchmark: annotations |
|
|
| **Write-up:** [Can image models spell the labels? A first look at my Tech Graphics Benchmark](https://blog.danielrosehill.com/posts/tech-graphics-benchmark-image-models-exact-text-first-look-i1f860/) |
|
|
| Raw human evaluation data for [Tech-Graphics-Benchmark](https://github.com/danielrosehill/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](https://huggingface.co/datasets/danielrosehill/Tech-Graphics-Benchmark) |
| - Generations (images + manifests): [danielrosehill/Tech-Graphics-Benchmark-Runs](https://huggingface.co/datasets/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](https://github.com/danielrosehill/Tech-Graphics-Benchmark#grading). |
