Evaluation of unconditional image generation models on the test split of the ImageNet dataset rendered at 64x64 resolution, typically measured using NLL (bits/dim).

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 | Unconditional Image Generation |
| Dataset (including any stated split) | ImageNet 64x64 (test) |
| Metric | FID |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 8 of 8 |
| 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

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

- [NLL (bits/dim)](<https://www.sota2.com/research/sota/unconditional-image-generation-on-imagenet-64x64-test.md?metric=NLL%20(bits%2Fdim)>): Lower is better; unit: SCALAR.

- [Recall](<https://www.sota2.com/research/sota/unconditional-image-generation-on-imagenet-64x64-test.md?metric=Recall>): Higher is better; unit: PERCENT.
