TokForge SD1.5-LCM — Photoreal (Realistic Vision V5.1)

A Realistic Vision V5.1 + LCM SD1.5 MNN bundle — the TokForge SD15_LCM_MNN fast few-step image model, but with the photoreal Realistic Vision V5.1 checkpoint as the base instead of DreamShaper-7. Renders a coherent, photorealistic 512px image in 4 steps on the in-process MNN diffusion engine — full MNN speed, the photoreal look baked into the UNet weights.

This is the Photoreal tier of the TokForge styled image catalog: natural skin, lifelike texture and lighting, true-to-life portraits and scenes. Verified on-device (OnePlus D9500 CPU, 4 steps, ~36 s) rendering a clean photorealistic candid portrait where the DreamShaper base renders a more stylized/cinematic look.

9-file MNN bundle: unet.mnn(.weight) (INT8, Realistic Vision V5.1 + LCM fused), reference SD1.5 f16 text_encoder.mnn(.weight) + vae_decoder.mnn(.weight), vocab.json, merges.txt, alphas.txt.

Provenance & licenses

• Base model: SG161222/Realistic_Vision_V5.1_noVAE — CreativeML-OpenRAIL-M (commercial-OK; redistribution of derivatives is licensed under OpenRAIL-M §III.4). RealisticVision V5.1 by SG_161222.
• LCM adapter: latent-consistency/lcm-lora-sdv1-5 — openrail++ (UNet-only consistency adapter, fused to keep the 4-step floor).
• CLIP / VAE / tokenizer: the standard SD1.5 reference assets (CLIP ViT-L/14 text encoder + SD1.5 VAE) reused verbatim from the TokForge base LCM bundle. Realistic Vision V5.1 ships "noVAE", so the standard SD1.5 VAE is used (the same VAE referenced by the DreamShaper bundle).

Note: The Lykon "Add More Details" detail-enhancer LoRA (Civitai 82098) was evaluated for additional skin/texture detail but is distributed in kohya format with text-encoder (lora_te_*) keys that the diffusers fuse converter cannot apply (raises IndexError); it is not included. Realistic Vision V5.1 already biases strongly photoreal on its own.

Modifications (OpenRAIL-M §III "mark modified")

This bundle is a modified derivative of Realistic Vision V5.1:

1. The LCM consistency adapter (lcm-lora-sdv1-5) is fused into the UNet (fp32 ΔW via diffusers.fuse_lora()) so the model is coherent at 4-8 steps with CFG≈1.0.
2. The fused UNet is exported to ONNX and converted to an INT8-quantized MNN model (MNNConvert, asymmetric 8-bit weight quant) for on-device CPU inference.
3. CLIP and VAE are the SD1.5 reference MNN assets, not Realistic Vision's own.

No retraining or fine-tuning of the original weights was performed beyond the LCM fuse + quant.
