PixelHacker inpainting — GGUF for CrispEmbed

Experimental. These files run only in CrispEmbed's native inpainting engine behind default-off gates (CRISPEMBED_PIXELHACKER=1, CRISPEMBED_INPAINT_QUANT=1 for F16/Q8_0/Q4_K). They are exact copies of the qualified files; nothing was requantized for publication.

Licence

• Code (upstream PixelHacker): Apache-2.0. Native ports also study flash-linear-attention (MIT).

Files and precision against the acceptance bars

Bars (final-output cosine, minimum over cases): F32 > 0.99, F16 > 0.98, Q8_0 > 0.97, Q4_K > 0.94. Synthetic-panel values compare with the original PyTorch model; real-photo values compare the masked region with native F32 (no original output exists for those photos).

The SDXL VAE companion files are in cstr/SDXL-VAE-inpaint-GGUF.

Use

See CrispEmbed docs/inpainting-cli.md and docs/inpainting-precision.md. Non-F32 files additionally need CRISPEMBED_INPAINT_QUANT=1.
