FLUX.2 Small Decoder is a distilled VAE decoder that serves as a drop in replacement for the standard FLUX.2 decoder. It delivers faster decoding and lower VRAM usage with minimal to zero quality loss. The encoder remains unchanged. Key Features 1. ~1.4x faster decoding compared to the full decoder. 2. ~1.4x less VRAM at decode time, enabling higher resolutions without running out of memory. 3. ~28M decoder parameters (vs ~50M in the full decoder) thanks to narrower channel widths ( [96, 192, 384, 384] vs [128, 256, 512, 512] ). 4. Minimal quality loss — images are almost identical. 5. Available under the Apache 2.0 license.

While the model can output text, text rendered may be inaccurate or subject to distortion. As a statistical model, this checkpoint may represent or amplify biases observed in the training data. The model may fail to generate output that matches the prompts. Prompt following is heavily influenced by the prompting style. Out of Scope…
