What do real open models actually see
in a chest X-ray?

Upload a chest X-ray. Three independently-trained, open-source models each score it on their own — shown separately, side by side, with a plain average only where they measure the same thing. No invented ensemble score. No clinical claim.

Not a diagnostic tool. RadioLens is an informational research demo only. It does not replace evaluation by a radiologist or clinician, is not validated for clinical use, and makes no error-rate or accuracy claims. Do not use it — or any output it produces — to make real medical decisions.

Three real models, cited by name

Two independently-trained DenseNet121 classifiers from the open-source torchxrayvision library, plus one architecturally-distinct Vision Transformer fine-tuned by a third party — a genuine cross-check, not one model wearing three hats.

DenseNet121 · aggregated

torchxrayvision / densenet121-res224-all

Trained on NIH ChestX-ray14 + PadChest + CheXpert + MIMIC-CXR + RSNA (aggregated). 18-label multi-pathology sigmoid output.

DenseNet121 · CheXpert

torchxrayvision / densenet121-res224-chex

Same architecture and library, independently trained on CheXpert (Stanford) only — a real second opinion, not a duplicate.

Vision Transformer

nickmuchi / vit-finetuned-chest-xray-pneumonia

ViT-base/16, fine-tuned by a third party on the Kaggle pediatric pneumonia dataset. A different architecture, different training group — the strongest cross-check in the set.

How it works

One workflow, deliberately narrow. No model picker, no marketplace, no NLQ.

01

Upload

A single chest X-ray, JPEG or PNG, up to 10 MB.

02

Run

All three models score it independently, in parallel.

03

Compare

Each model's raw output shown under its own name, never pre-blended.

04

Read

A plain average and agreement note, only where models measure the same thing.
