MOSS-Image Psychedelic LoRA GGUF

Separate F16 GGUF conversion of the psychedelic-pop LoRA from axiomofmind/Moss-image-psychedelic-lora. It is designed to be applied at inference time to axiomofmind/Moss-Image-SFT-GGUF, keeping the adapter strength adjustable and avoiding a separate merged model for every quantization or scale.

This repository contains the LoRA adapter only. It does not contain the base diffusion transformer, Qwen3.5 text encoder, tokenizer, or VAE.

File

The adapter uses rank 16 and alpha 16. Its trigger phrase is moss_psychpop_style; place it at the beginning of the prompt. Scale 1.0 is the recommended starting point, with 1.0–1.2 producing the strongest preferred results in local evaluation.

Required components

• A compatible base transformer from Moss-Image-SFT-GGUF. Q8_0 was validated; Q4_K_S uses the same MOSS architecture and LoRA targets.
• A MOSS-enabled stable-diffusion.cpp build.
• A Qwen3.5-9B text encoder, the official MOSS tokenizer.json, and the official MOSS / FLUX.2 VAE. See the base GGUF repository for links and setup notes.

Usage

Put the base GGUF and this LoRA GGUF in accessible locations. The <lora:...> tag selects the adapter file and scale; moss_psychpop_style is the learned trigger sent to the text encoder.

  -o psychpop-gguf.png

Quantized transformers automatically select runtime LoRA application. --lora-apply-mode at_runtime is explicit here because it is the validated path. Ready-to-edit PowerShell and Bash wrappers are provided under examples/.

Controlled validation

The adapter was tested with MOSS-Image-SFT-Q8_0.gguf. Both images below used the same description, base model, text encoder, VAE, 1024×1024 resolution, 30 steps, CFG 3, Euler/discrete sampling, flow shift 5, and seed 42.

• The stock prompt omitted both the trigger phrase and LoRA tag.
• The adapter prompt added moss_psychpop_style and <lora:MOSS-Image-Psychedelic-LoRA-F16:1.0>.
• stable-diffusion.cpp reported all 504 / 504 LoRA tensors applied.

Timings were measured on an NVIDIA RTX PRO 6000 Blackwell Max-Q and are correctness checks, not general performance benchmarks.

Conversion

Converted independently from pytorch_lora_weights.safetensors using stable-diffusion.cpp commit b13a482:

sd-cli.exe -M convert `
  -m pytorch_lora_weights.safetensors `
  -o MOSS-Image-Psychedelic-LoRA-F16.gguf `
  --type f16 `
  --convert-name `
  -t 16

The source adapter was trained for 1,250 steps at rank/alpha 16/16. See conversion.json for machine-readable conversion and validation metadata.
