0.18.33-CV

🎨 New Features

• NVIDIA PiD pixel-diffusion decoder (--pid-decode): replaces the VAE decode with NVIDIA's PiD, a 4x super-resolving re-render of the final latents, so a 512x512 generation decodes straight to 2048x2048. Wired on FLUX.1, FLUX.2 Klein, Qwen Image, Krea 2, ERNIE, Ideogram 4 and Z-Image (which shares Flux's latent space and uses its PiD checkpoint). Opt-in and off by default; the normal decode path is untouched. Weights download at runtime: one model_ema_bf16.pth per VAE family from nvidia/PiD plus google/gemma-2-2b-it (gated, accept the license once). --pid-degrade-sigma trades source fidelity for invented detail, and with --pid-decode the transformer is evicted the moment the denoising loop ends, which upstream measured as a straight win. From upstream #490 by @azrahello at its post-review state, with the degrade-sigma piece co-authored by @plz12345, who also verified it with real runs on five model families. Documented behaviors carried as-is: the 4x output re-draws rather than sharpens, portrait skin can over-texture, and flux2-checkpoint families show a small green drift with an upstream correction promised as follow-up. One deliberate divergence: the sampler threads explicit RNG keys instead of reseeding the global stream, so multi-seed runs stay reproducible with and without --pid-decode. (#40)
