Evaluation of Class-conditional Image Synthesis models on the validation split of ImageNet rendered at 512x512 resolution (version 1.0), typically measured by FID, IS, Precision, Recall, and CAS metrics.

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 | Class-conditional image synthesis |
| Dataset (including any stated split) | ImageNet 512x512 1.0 (val) |
| Metric | FID |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 4 of 4 |
| 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/class-conditional-image-synthesis-on-imagenet-512x512-1-0-val.md?metric=FID>): Lower is better; unit: SCALAR.

- [IS](<https://www.sota2.com/research/sota/class-conditional-image-synthesis-on-imagenet-512x512-1-0-val.md?metric=IS>): Higher is better; unit: SCALAR.

- [Precision](<https://www.sota2.com/research/sota/class-conditional-image-synthesis-on-imagenet-512x512-1-0-val.md?metric=Precision>): Higher is better; unit: PERCENT.

- [Recall](<https://www.sota2.com/research/sota/class-conditional-image-synthesis-on-imagenet-512x512-1-0-val.md?metric=Recall>): Higher is better; unit: PERCENT.

- [CAS Top-1](<https://www.sota2.com/research/sota/class-conditional-image-synthesis-on-imagenet-512x512-1-0-val.md?metric=CAS%20Top-1>): Higher is better; unit: PERCENT.

- [CAS Top-5](<https://www.sota2.com/research/sota/class-conditional-image-synthesis-on-imagenet-512x512-1-0-val.md?metric=CAS%20Top-5>): Higher is better; unit: PERCENT.
