GRIP-Benchmark
GRIP-Benchmark is a fully synthetic, programmatically generated and independently validated visual geometry, spatial-reasoning, and physical-reasoning suite. The current release contains 34 categories, 100,000 unique images, and 500,000 image-question rows. Every image is paired with five questions ordered from direct perception through extrapolative/counterfactual reasoning.
The repository provides data and ground truth only. It does not include model inference, scoring, or an evaluation harness.

3. Shared methodology
Unified five-level question progression
Every image has exactly five questions in increasing order of difficulty:
- Level 1 — Simple Description: perceive one directly visible fact with no inference.
- Level 2 — Basic Relational: perform one comparison or one-step rule application.
- Level 3 — Comparative/Structural: reason across multiple elements, rank them, identify an extreme, or cross-reference image regions.
- Level 4 — Compound Reasoning: combine at least two facts or apply a multi-step formula/rule chain without hypothetical framing.
- Level 5 — Extrapolative/Counterfactual: apply an explicitly defined hypothetical geometric change, extrapolate beyond the shown pattern, or explain a deterministic consequence.
The exact question templates differ by category, but this progression and the difficulty_level: 1..5 annotation contract are shared by all 34 datasets. Every Level 5 operation is independently recomputable from raw stored geometry or scene metadata. Flattened CSV/JSONL files contain one row per question, yielding 15,000 rows per core dataset and 5,000 for the focused projectile-motion category.
Free-body-diagram Level 4 questions introduce the structured private scoring declaration {"type":"numeric_tolerance","tolerance_percent":2} for real-valued mechanics answers. This field appears in annotations and private answer keys, not public question sets; it changes grading precision without exposing an acceptance band to a tested model.
Independent validation
Generation-time assertions are not treated as sufficient evidence. Each sub-benchmark has a separate validator that reconstructs answers from raw scene geometry or metadata. Depending on the task, validators use exact-cover search, graph recomputation, affine reflection, dot products, coordinate formulas, polyhedral/voxel enumeration, geometric containment, or projective shadow calculations.
Validation follows a common pattern:
- re-derive ground truth rather than trusting stored answer fields;
- check constraints and reject ambiguous cases such as ties, accidental collinearity, invalid transformations, clipping, or degenerate geometry;
- recompute all five question answers;
- audit expected dataset-level distributions;
- where image/label divergence is a material risk, read the final PNG from disk and check rendered components, locations, silhouettes, or line geometry.
Every dataset folder contains its generator, raw annotations, flattened outputs, validation report, contact sheet, and dataset-specific README.
For suite-wide manual review of the original 29-category release, see spot_check_review, which preserves five low-, five medium-, and five high-difficulty images per included dataset: 435 images total, a long-form 2,175-row five-question answer key, and a consolidated 29×15 contact sheet. The deterministic seed is 20260814.
Dataset Structure
The Hub release uses one unified train split with 500,000 rows and the following schema:
| Field | Type | Description |
|---|---|---|
id |
string | Globally unique identifier such as route_0001_q1 |
image |
Image | Embedded image bytes; the dataset is self-contained |
category |
string | One of the 34 benchmark categories |
question |
string | Question prompt |
ground_truth |
string | Validated answer |
metadata |
string | Compact JSON metadata retained from the source dataset |
Example (image omitted from the textual representation):
{
"id": "route_0001_q1",
"category": "route",
"question": "How many distinct colored routes are visible in this image?",
"ground_truth": "7",
"metadata": "{\"difficulty_score\":0.42,\"num_routes\":7}"
}
Each unique image appears in five rows with different IDs, questions, and answers but identical embedded image content.
Loading
from datasets import load_dataset
dataset = load_dataset("bilaljawaid980/GRIP-Benchmark", split="train")
Validation and limitations
Ground truth is independently re-derived from stored scene geometry or structured metadata by category-specific validators. Known limitations include synthetic rather than photographic imagery, bounded shape/rule vocabularies, and category-specific procedural distributions. These data should be treated as a diagnostic benchmark, not as a substitute for real-world spatial reasoning evaluation.
