T4 Proof — Open Model Reality Check
Not estimated. Actually run. This dataset tracks reproducible runs of trending open models on Kaggle's free Dual Tesla T4 environment.
What makes a run verified?
A row may be a candidate, running, failed, or verified. Verified is reserved for a run that has all of the following:
- a recorded Kaggle hardware and software environment;
- a fixed, representative input and generation configuration;
- cold-start, peak-VRAM, and task timing measurements;
- an inspectable output artifact;
- logs or a notebook sufficient to reproduce the result.
A successful model import alone is not a verified task run.
Files
data/benchmarks.json— dashboard records and current queue.schema/benchmark-result.schema.json— validation contract.README.md— this dataset card.
Hardware baseline
The initial environment probe recorded two Tesla T4 GPUs with 14.56 GiB usable VRAM each, CUDA 12.8, and PyTorch 2.10.
Live dashboard
The interactive board is available at T4 Proof.
Limitations
The dataset starts intentionally small. Candidate status is not a performance claim. Results are specific to the recorded revision, precision, runtime, and task adapter; they should not be generalized to different model revisions or hardware.
License
Dataset metadata and benchmark harness: Apache-2.0. Individual model licenses remain with their respective publishers and are recorded per row.
