Evaluation of image generation models on the training split of the ImageNet dataset downsampled to 64x64 resolution, typically measured using Inception Score (IS), FID, and sFID.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Image Generation |
| Dataset (including any stated split) | ImageNet 64x64 down-sampled (train) |
| Metric | IS |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 6 of 6 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [IS](<https://www.sota2.com/research/sota/image-generation-on-imagenet-64x64-down-sampled-train.md?metric=IS>): Higher is better; unit: SCALAR.

- [FID](<https://www.sota2.com/research/sota/image-generation-on-imagenet-64x64-down-sampled-train.md?metric=FID>): Lower is better; unit: SCALAR.

- [sFID](<https://www.sota2.com/research/sota/image-generation-on-imagenet-64x64-down-sampled-train.md?metric=sFID>): Lower is better; unit: SCALAR.
