RUM FLUX.2 Klein 4B ConvRot Quantized
Post-training ConvRot quantizations of RUM-FLUX.2-klein-4B-preview, based on FLUX.2-klein-base-4B. The repository provides a quality-first INT8 model and a smaller hybrid INT4 model. RUM's dual text-conditioning projections and sensitive input, output, normalization, and modulation layers remain in BF16.

Download the FLUX.2 Klein 4B base model and the SDXL/WAI teacher checkpoint separately, then pass their local paths to standalone_inference.py. Run python standalone_inference.py --help for all options. The recommended defaults are 20 steps for text-to-image and 10 steps for editing.
