pruna-vaed-mlx
MLX conversion of PrunaAI/PrunaVAED — a pruned LTX-2.3 video VAE decoder for Apple Silicon.
Converted with mlx-forge (pruna-vaed recipe): Conv3d weights transposed to MLX channels-last; per_channel_statistics injected from stock dgrauet/ltx-2.3-mlx.
Important
This is not a drop-in replacement for stock vae_decoder.safetensors. Channel widths and skip conv_in projections differ. Load with a Pruna-aware decoder graph (e.g. ltx-ws VideoDecoderPruna / ltx-2-mlx port of patched diffusers LTX2VideoDecoder3d).
