Nacre v1 โ€” MLX layout

The Nacre v1 weights converted for the Swift/MLX port (mlx-nacre-swift): conv weights OHWI, per-tensor exact from the release (oracle/convert_weights.py). Two tensors of the release are not parameters of the MLX module tree and are omitted: the Swin relative_position_index buffers (rebuilt from the window size) and the VQ codebook (Nacre decodes continuous latents).

nacre_v1_mlx_fp16.safetensors + vq_f4_mlx_fp16.safetensors shipping (every reduction is fp32 inside the port)
nacre_v1_mlx_fp32.safetensors + vq_f4_mlx_fp32.safetensors parity

Licences, provenance, metrics and limitations: see the main model card. The VQ-f4 autoencoder is CompVis (MIT); see NOTICE.
