BitResEdit: Training-free bitwise residual editing for visual autoregressive image generators

BitResEdit is a training-free text-guided image editing method for bitwise-residual visual autoregressive (VAR) models, specifically targeting Infinity-2B. The approach combines per-bit Bernoulli guidance (BitEdit) with scale-aware code residual injection (ResEdit), exploiting native structures of VAR models that prior editors leave unused. On PIE-Bench with Infinity-2B, it achieves the best CLIP text alignment among same-backbone VAR editors (+1.07 over the prior best) while maintaining competitive background preservation.
