SANA 1600M 1024px — SceneWorks MLX mirror

Un-gated, repackaged mirror of Efficient-Large-Model/Sana_1600M_1024px_diffusers for the SceneWorks native MLX worker (mlx-gen-sana).

The tensors are copied verbatim (dtype-preserving — no conversion, no re-quantization) into the directory layout that SanaPipeline::from_snapshot expects:

transformer/diffusion_pytorch_model.safetensors   # SANA 1.6B Linear-DiT trunk (F16)
vae/diffusion_pytorch_model.safetensors           # 32x DC-AE f32c32 decoder (F32)
text_encoder/gemma-2-2b-it.safetensors            # gemma-2-2b-it CHI caption encoder (BF16)
text_encoder/tokenizer.json

The gemma-2-2b-it text encoder is sourced from the un-gated SceneWorks/gemma-2-2b-it mirror (merged from its two shards into one file) so the SANA snapshot is self-contained.

License

The SANA transformer and DC-AE VAE weights are licensed under the Apache License 2.0 (see LICENSE). NVIDIA relicensed them from the earlier non-commercial NVIDIA license to Apache-2.0 on 2026-07-31 in Efficient-Large-Model/Sana_1600M_1024px@d71cbc8e and Efficient-Large-Model/Sana_1600M_1024px_diffusers@ac0da2ff ("Relicense model under Apache-2.0"). The weight files are byte-identical before and after that relicence, so the grant covers the bytes mirrored here.

The bundled gemma-2-2b-it text encoder (text_encoder/ in every tier) is provided under and subject to the Gemma Terms of Use found at https://ai.google.dev/gemma/terms (copy: GEMMA_TERMS_OF_USE), including the use restrictions of the Gemma Prohibited Use Policy (https://ai.google.dev/gemma/prohibited_use_policy, copy: GEMMA_PROHIBITED_USE_POLICY.md). Those restrictions apply to anyone who uses or redistributes the text encoder.

See NOTICE. This mirror adds no additional grant.
