Clark Air releases 8x smaller Sana 1.6B model with minimal quality loss

Clark Air has released a compressed version of their Sana 1.6B model, significantly reducing its size while aiming to maintain quality. The model, now in a packed ternary format, is 374 MB compared to the original 3.21 GB FP16 transformer, achieving an 8x compression with minimal loss. This release is positioned as a research artifact, offering a more efficient alternative to native Int4 quantization for image generation. AI

IMPACT Offers a significantly smaller model for image generation, potentially enabling wider use on resource-constrained devices.
