<h1 id="artius-moss-v2">Artius Moss v2</h1>A realistic portrait. A floating city. That oddly specific idea you’ve been meaning to try.Artius Moss gives you room to explore them all. Version 2 is a versatile, photorealistic MOSS-Image merge with a new merge pipeline, an HDR fine-tune, and sharper built-in turbo. Create clean images in 8–10 steps, switch styles, and keep experimenting — even on a GPU with 8 GB VRAM.⚡ 8–10 steps · CFG 1 · ~7 GB model · runs on 8 GB GPUs 📦 Custom text encoder and Flux 2 VAE available on this page<h2 id="what's-new-in-v2">🆕 What’s new in v2</h2>A different, more advanced merge. v2 is a full rebuild, not a cosmetic update. It uses a new merge pipeline built around full-rank orthogonalized deltas: the sources are separated more cleanly before they are combined, so their useful differences survive instead of stacking the same emphasis over and over. The result is cleaner structure, finer detail, and fewer merge artifacts.HDR fine-tune. After the merge, v2 received an additional fine-tune on a curated HDR dataset. This is a major part of the v2 look: wider tonal range, better highlight roll-off, deeper shadows with retained detail, stronger microcontrast, and sharper skin, fabric, hair, and environmental texture.Better built-in acceleration. The turbo path was retuned for 8–10 steps at CFG 1. v2 is sharper and more coherent at the same speed — 8 steps works for quick exploration, and 10 steps gives a clear detail boost without turning generation into a waiting game.A balanced generalist, not a one-note NSFW merge. Unlike the many narrow NSFW merges that push every prompt toward the same glossy look, v2 is built to stay flexible. It can produce super-detailed photorealism, anime, illustration, graphic art, fantasy, fashion, landscapes, and whatever else you throw at it — without stamping one style onto every image.<h2 id="one-model.-plenty-of-directions.">🎨 One model. Plenty of directions.</h2>Start with a portrait in soft window light. Try a rainy street glowing with neon. Then build a tiny village on the back of a giant turtle.Artius Moss is made to move between photorealism, illustration, fantasy, fashion, landscapes, and more. The fine-tune and LoRA strengths were tested side by side and adjusted to work together, giving you a broad range of styles without stamping the same look onto every image. v2’s HDR pass adds extra depth to that range: soft light has more shape, neon has cleaner color separation, and detailed scenes hold up better when you look closely.Bring a detailed prompt or start with a simple idea. There’s room for both.<h2 id="made-for-experimenting">✨ Made for experimenting</h2>Fast from the start. Turbo is already built in. Use 8 steps for quick experiments or 10 for a little extra detail. v2’s retuned acceleration makes both settings more usable, with better sharpness at the same step count.A new style is a prompt away. Explore realistic photography, painted worlds, character art, anime, graphic illustration, or something harder to put a name to — all with the same model.Comfortably compact. The optimized INT8 model is around 7 GB and runs in ComfyUI on GPUs with 8 GB VRAM.A custom encoder for your prompts. The included Qwen3.5-9B text encoder was prepared specifically for this model. It can also expand a short idea into a more detailed prompt using ComfyUI’s TextGenerate node.A workflow you can pick up and use.

The compact INT8 build comes later, through quantization.<h3 id="hdr-fine-tune-on-top-of-the-merge">🌅 HDR fine-tune on top of the merge</h3>After the merge, v2 was fine-tuned on an HDR-focused dataset. The goal was not to narrow the style range, but to improve the way the model handles light and detail: brighter highlights without clipping, deeper shadows with retained information, cleaner microcontrast, and sharper texture in skin, hair, fabric, foliage, and architecture.<h3 id="full-precision-before-quantization">🔬 Full precision before quantization</h3>All LoRAs are merged in FP32 before quantization, helping preserve fine details during the merge.<h3 id="each-block-gets-individual-attention">⚖️ Each block gets individual attention</h3>The model’s blocks were evaluated for their sensitivity to quantization.
