2025-07-23 Test Notes
|
| 84 |
+
|
| 85 |
+
- FP4 quantization model loads successfully in ComfyUI, but isn’t fully functional yet. Needs further investigation and debugging.
|
| 86 |
+
|
| 87 |
+
- Calibration dataset appears misaligned, may need to revisit and adjust the sampling code for Flux.1 Kontext Dev.
|
| 88 |
+
|
| 89 |
+
- Later, consider running another test using the base [black-forest-labs/FLUX.1-dev](https://huggingface.co/black-forest-labs/FLUX.1-dev/tree/main) model for comparison.

- Check with the deepcompressor/nunchaku team, request their latest working implementation.
