MOSS-Image Text to Image | 4-Step Turbo + SeedVR2 2x

Make pictures with MOSS-Image, the new open model that writes the words you give it. Signs, menus, posters and labels come out spelled right when you put the words in "double quotes". Four switches help: Auto prompt writes a full prompt from a few words, Start from a picture describes a picture of yours and adds your changes, Layout boxes puts things and words where you draw them, and Enlarge 2x with SeedVR2 makes the finished picture twice as big and sharper. A Steps pill picks 50 steps, or 8 or 4 with a speed LoRA for a picture in about two seconds.

How to use it

1. Type your prompt. Put every word you want in the picture in "double quotes".

2. Set the size in Latent Size.

3. Run.

The switches

• Auto prompt. The text encoder MOSS already uses turns a few words of yours into a full prompt, and writes out every word that belongs on a sign, a menu or a poster. What it wrote shows in Show Text. A second or two more, no extra download.

• Start from a picture. Load a picture of yours. The encoder describes it and adds what you typed ("make it a rainy night", "the sign says LAST TRAIN"), then MOSS draws a new picture from that description. A slider shows yours beside the new one. MOSS draws the scene again rather than editing your picture, so faces and small things change.

• Layout boxes. Draw a box for each thing or line of words and say what goes in it. Your prompt still describes the whole picture. The canvas starts empty.

• Enlarge 2x with SeedVR2. SeedVR2 3B makes the finished picture twice as big on each side and sharper: 1024 x 1536 becomes 2048 x 3072, about 3 to 4 seconds more on an RTX 5090. It also takes away the softness of 8 and 4 steps. It sharpens a blurred background too, and small blurry writing can get made-up letters. It needs two more files (below); with the switch off they are not loaded.

All four are off as the file opens.

Steps

• 50 steps: the settings OpenMOSS gives, the most detail. About 18 seconds for 1.5 megapixels on an RTX 5090.

• 8 steps or 4 steps: a speed LoRA makes the picture in about 2 seconds or 1.5. It comes out a little softer than 50 steps; Enlarge 2x with SeedVR2 makes it sharp again.

• Only one can be picked. The pill sets the steps and CFG and turns the matching row on in LoRA Loader. If its LoRA is missing, the run stops and names the file.

50 steps is picked as the file opens.

What you need

• ComfyUI's development version from 2026-10-16 or newer. MOSS-Image support is merged but not in a release yet. Windows portable: run update/update_comfyui.bat, not the _stable one. A git install: git pull on master, then pip install -r requirements.txt. The Desktop app gets it with ComfyUI's next release.

• AusBoss nodes 2.15.0 or newer. In ComfyUI-Manager, search "AusBoss". Already have them? Update first.

  Can't update yet? Pick MOSS-Image Text to Image (AusBoss, core boxes).json in the Download box. It is the same workflow for AusBoss nodes 2.13 or 2.14, with ComfyUI's own box node, whose canvas draws only in the Nodes 2.0 view.

• The MOSS-Image files from Comfy-Org/MOSS-Image:

  • moss_image_sft_int8_convrot.safetensors → models/diffusion_models · 5.41 GB

  • qwen3.5_9b_int8_convrot.safetensors → models/text_encoders · 9.75 GB

  • flux2-vae.safetensors → models/vae · 336 MB

• For 8 and 4 steps, the speed LoRAs → models/loras · 1.19 GB each:

  • lora_latest.safetensors by lodestones, for 8 steps

  • MOSS-Image-SFT-4-steps by akhaliq, for 4 steps. It downloads as lora.safetensors: rename it MOSS-Image-SFT-4-steps.safetensors.

• For Enlarge 2x, SeedVR2 from Comfy-Org/SeedVR2:

  • seedvr2_3b_int8_convrot.safetensors → models/diffusion_models · 3.46 GB

  • seedvr2_ema_vae_fp16.safetensors → models/vae · 501 MB

The INT8 file gives the same picture as the full-size one (moss_image_sft_bf16, 10.2 GB), about 2.4 times faster. For a smaller card there is a smaller text encoder, qwen3.5_9b_w4a8_gptq (7.34 GB): pick it in Text encoder.

Tips

• Spell out every word. MOSS writes exactly the words you give it. Words it has to make up come out as gibberish, so put them in quotes, or let Auto prompt write them. Up to about 40 words came out right in my tests; a full page of text is too much.

• Write "a young woman in her twenties" rather than "girl". MOSS draws a child for "girl". Auto prompt does this for you.

• Start from a picture draws the person again from a description. If they come out looking different, say how they look in your words: "she has pale skin and freckles".

• Faint vertical stripes on a smooth sky or wall are a known quirk of this model. MATLOWAI's two DeBand LoRAs together, both at strength 1 in LoRA Loader, removed them in my tests; one alone barely helps.

• Settings: 50 steps at CFG 3 with layer 22 skipped on the negative, the settings OpenMOSS gives. On an RTX 5090 a 1.5 megapixel picture takes about 18 seconds, about 20 with Auto prompt or a picture. 8 and 4 steps run at CFG 1, as the speed LoRAs ask.

• Size: 1 to 2 megapixels works best. The picture keeps the size you set in Latent Size, also with Start from a picture. Enlarge 2x doubles it on each side.

What it does not do

• No editing. MOSS-Image draws new pictures from words. Start from a picture describes yours and draws a new one; it does not change your picture in place.
