- Add Transformers v5 tokenizer compatibility fix for SDNQ Klein models
Downloads missing vocab.json, merges.txt, tokenizer_config.json from
Z-Image-Turbo when needed
- Detect SDNQ repos and disable shared text encoder to use pre-quantized
weights from the SDNQ repo instead of loading from shared base model
- Update reference-quant.json with correct preview images and metadata
for Klein SDNQ models
- Update reference-distilled.json with correct cfg_scale (1.0) for
distilled Klein models per official HuggingFace documentation
- Add 6 Klein model preview images
- Fix Klein text encoder comment to specify correct sizes per variant
- Lock TAESD decode logging behind SD_PREVIEW_DEBUG env var
- Fix misleading comment about FLUX.2 128-channel reshape (is fallback)
- Remove VRAM requirements from model descriptions in reference files
Add support for FLUX.2 Klein distilled models (4B and 9B variants):
- Add pipeline loader for Flux2KleinPipeline
- Add model detection for 'flux.2' + 'klein' patterns
- Add pipeline mapping in shared_items
- Add shared Qwen3ForCausalLM text encoder handling:
- 4B variants use Z-Image-Turbo's Qwen3-8B
- 9B variants use FLUX.2-klein-9B's Qwen3-14B
- Add reference entries for distilled (4B, 9B) and base models
- Update diffusers commit for Flux2KleinPipeline support
