There is some color tint is observed. I'm not sure I like it.

Lots of body horrors in hands and nails.

Nothing particularly impressive but it's okay in 1girl images I guess.

Well it's always good to have more free models.

The transparency support is nice too.

All generated in comfy template workflow, 25 steps, euler, simple. I think we have to increase the steps to 40~50, but I didn't bother.

(1) Upload fp16 safetensors to google drive

Check if you have enough disk space for int8 convrot output (about half size of fp16)

(2) Visit https://colab.research.google.com/

Check Menu >Runtime >Here, change runtime type to gpu

(3) Create a new note

(4) Create a first code cell (mounting google drive), copy paste the following, and run it

from google.colab import drive
drive.mount('/content/drive')

(5) Create a second code cell (installing git repo), copy paste the following, and run it

!pip install git+https://github.com/silveroxides/convert_to_quant.git
!pip install triton

(6) Create a third code cell (converting to int8), copy paste the following, and run it

!ctq \
  -i "/content/drive/MyDrive/NameOfTheModel-fp16.safetensors" \
  -o "/content/drive/MyDrive/NameOfTheModel-int8-convrot.safetensors" \
  --int8 \
  --scaling_mode row \
  --convrot \
  --convrot-group-size 256
  --exclude-layers "(embed_tokens|lm_head|norm)" \
  --comfy_quant \
  --save-quant-metadata \
  --simple \
  --low-memory

Change input file name (-i) and output file name (-o)

Scaling mode is 'row' by default and is said to be more accurate than 'tensor'

You need to learn ideal group size and exclude-layers for each model (by googling or asking chatbot)

Optionally, run the following code in a new code block to check the presets for exclude layers

!ctq --help-filters

Then you can replace the one you want with the '--exclude-layers' line.

Lastly, render with fp16 and int8 convrot in comfy to see if it works.

I think it is because it's the same as z image turbo, this variant lacks variety while raw/base has variety, and that is for training. But, lack of variety seems to be helpful with text-to-image character consistency very much.

If you want to try, talk with any chatbot for 1 minute and make a consistenct character you want across the scenes yourself.

All my sloppy prompts are also generated by ai chatbot, and if you don't want to spend a minute of your time with it, I don't know what to say to you.

All prompts star with "a young latina woman" I described the woman to chatbot and I didn't even check what it wrote. It's safe to say it's 100% mess.

But, it is useful to me for the sake of fast testing. Understand that I don't want to waste time like anyone else.

prompt1 - a day in bikini city

A young Latina woman walks casually through a colorful underwater city street, captured in a spontaneous candid moment as she carries a small shopping bag and turns her head toward the camera with a relaxed confident expression. Her warm light tan complexion, almond-shaped dark eyes enhanced with dramatic smoky eye makeup and winged eyeliner, softly arched brows, defined cheekbones, narrow jawline, slender nose, and glossy soft pink lips remain completely photorealistic. Her lean yet distinctly curvy hourglass physique features a prominent bust, narrow ribcage, slim waist with subtle oblique definition, toned abdomen, rounded hips, full thighs, and feminine athletic arms. She has medium-long dark chocolate brown shag haircut with heavily textured layers, soft curtain bangs naturally framing her face, slightly tousled lived-in texture, subtle crown volume, and effortless movement floating naturally underwater. She wears a fitted black long-sleeve collared dress with a crisp white pointed collar and white French cuffs, tailored through the waist with an above-the-knee A-line silhouette, matte black opaque tights, and polished black leather lace-up ankle boots. A chunky silver skull ring, stacked black leather wristbands, and a detailed black-and-gray thorned rose vine tattoo wrapping around her right forearm are clearly visible. Her fingernails are painted glossy deep red. She appears as a completely photorealistic live-action person with realistic skin texture, individual hair strands, natural fabric behavior, subtle water movement, and authentic analog film grain.

A candid underwater 35mm street photograph in a colorful cartoon ocean city. The woman is the only photorealistic element in the entire image. Every other visible element—including underwater buildings shaped like whimsical objects, coral trees, sea plants, colorful signs, cartoon sea creatures walking through the street, unusual vehicles, and all background details—is rendered exclusively in classic SpongeBob-style 2D animation with bold outlines, flat saturated colors, playful shapes, and exaggerated cartoon proportions. The woman appears like a real human who has mysteriously entered an animated underwater universe. Bright turquoise ambient water light, colorful reflections, soft particles floating underwater, shallow depth of field, realistic underwater photography, Kodak-style film colors, documentary street photography feeling.

prompt2 - waiting for famous burger

A young Latina woman sits alone at a small restaurant table inside a quirky underwater fast-food restaurant, captured in a casual candid moment as she looks over a menu while resting one arm on the table. Her warm light tan complexion, almond-shaped dark eyes with smoky eye makeup and winged eyeliner, defined cheekbones, narrow jawline, slender nose, glossy pink lips, and realistic facial features remain completely photorealistic. Her curvy hourglass silhouette, dark chocolate brown shag haircut with textured layers and soft curtain bangs, and natural human proportions remain unchanged. She wears the fitted black collared dress with white pointed collar and cuffs, matte black tights, and black leather lace-up boots. Her chunky silver skull ring, black leather wristbands, thorned rose vine tattoo on her right forearm, and glossy deep red nails are clearly visible.

A candid 35mm restaurant photograph inside a completely animated underwater diner. The woman is the only realistic photographic element. The restaurant interior, wooden tables, kitchen equipment, menu boards, food items, colorful sea creature customers, workers, walls, windows, and every environmental detail are rendered exclusively in classic SpongeBob-style 2D cartoon animation with bold black outlines, flat colors, exaggerated shapes, and playful underwater design. The contrast creates the feeling that a real woman is having lunch inside a cartoon ocean world. Warm interior lighting mixed with blue underwater glow, realistic skin highlights, shallow depth of field, subtle analog film grain, authentic lifestyle photography.

prompt3 - walk in jellyfish field

A young Latina woman slowly walks through a glowing underwater meadow filled with floating jellyfish and colorful coral, captured in a peaceful candid photograph as she reaches one hand toward a drifting jellyfish while looking at it with curiosity. Her warm light tan skin, almond-shaped dark eyes, dramatic smoky eye makeup, winged eyeliner, softly arched brows, defined cheekbones, narrow jawline, slender nose, and glossy soft pink lips remain completely photorealistic. Her dark chocolate brown shag haircut with textured layers and curtain bangs moves naturally with the underwater current. Her realistic hourglass figure remains unchanged, wearing the fitted black collared dress, white collar and cuffs, black tights, and lace-up leather boots. Her skull ring, leather bracelets, thorned rose tattoo, and deep red nails are visible.

A dreamy underwater 35mm analog photograph surrounded by a completely animated fantasy ocean landscape. The woman is the only photorealistic element. The floating jellyfish, coral formations, underwater plants, distant creatures, bubbles, colorful terrain, and all environmental elements are rendered exclusively in classic SpongeBob-style 2D animation with bright flat colors, thick outlines, and whimsical cartoon forms. The image feels like a real fashion photograph taken inside a hand-drawn underwater world. Soft aqua lighting, colorful underwater glow, gentle floating particles, realistic human skin reflections, cinematic depth of field, nostalgic analog photography aesthetic.

prompt4 - bus stop to springfield

A young Latina woman waits casually at an underwater bus stop, captured in a realistic candid street photograph as she checks her phone while standing among unusual cartoon ocean residents. Her warm light tan complexion, almond-shaped dark eyes, smoky eye makeup, winged eyeliner, defined cheekbones, narrow jawline, slender nose, glossy pink lips, and realistic facial structure remain unchanged. Her dark chocolate brown shag haircut with layered texture and soft curtain bangs frames her face naturally. She wears the fitted black collared dress with white pointed collar and cuffs, black tights, and polished leather lace-up boots. Her silver skull ring, stacked leather wristbands, thorned rose tattoo, and glossy red nails remain visible.

A handheld 35mm underwater street photograph at a colorful cartoon bus stop. The woman is the only live-action human element. The bus shelter, strange underwater vehicles, cartoon sea creatures waiting nearby, signs, buildings, coral, plants, and all background details are rendered exclusively in classic SpongeBob-style 2D animation with bold outlines, flat vibrant colors, and exaggerated cartoon geometry. The scene feels like an ordinary real-life commute happening inside an animated ocean universe. Bright daytime underwater lighting, realistic shadows on the woman, shallow depth of field, authentic documentary photography, subtle film grain.

prompt5 - meeting with the simpsons

A young Latina woman sits comfortably on a cartoon living room sofa during an unusual quiet moment, surrounded by animated residents while appearing completely real. She looks relaxed and slightly amused, resting one arm naturally while her tattooed forearm and silver accessories remain visible. Her photorealistic face features warm light tan skin, almond-shaped dark eyes, smoky eye makeup, winged eyeliner, defined cheekbones, narrow jawline, slender nose, and glossy pink lips. Her dark chocolate brown shag haircut with textured layers and curtain bangs frames her face naturally. Her fitted black gothic-academic dress, white collar, white cuffs, black tights, and lace-up boots contrast sharply against the colorful cartoon interior.

A cinematic candid photograph inside the Simpsons family's living room, captured with a realistic 35mm camera. The woman is the only real human element. Homer, Marge, Bart, Lisa, Maggie, the furniture, television, walls, decorations, and every environmental detail are rendered exclusively in traditional Simpsons-style 2D animation with flat colors and thick black outlines. The scene feels like a real person accidentally photographed inside a cartoon universe. Warm indoor lighting, soft shadows, realistic film grain on the woman only, shallow depth of field, documentary photography style.

prompt6 - last night at moe

A young Latina woman sits alone at the worn wooden counter of a dim neighborhood bar, captured in a spontaneous candid moment as she looks slightly toward the camera while holding a glass of soda in one hand. Her warm light tan complexion, almond-shaped dark eyes with dramatic smoky eye makeup and winged eyeliner, softly arched brows, defined cheekbones, narrow jawline, slender nose, and glossy soft pink lips remain completely photorealistic. Her lean yet distinctly curvy hourglass physique features a prominent bust, narrow ribcage, slim waist, toned abdomen, rounded hips, full thighs, and feminine athletic arms. She has medium-long dark chocolate brown shag haircut with heavily textured layers, soft curtain bangs naturally framing her face, slightly tousled lived-in texture, subtle crown volume, and effortless movement. She wears a fitted black long-sleeve collared dress with a crisp white pointed collar and white French cuffs, tailored through the waist with an above-the-knee A-line silhouette, matte black opaque tights, and polished black leather lace-up ankle boots.

Warm neon lighting, red and amber reflections, soft shadows, Kodak Portra-style color rendition, shallow depth of field, realistic low-light photography, subtle grain, documentary candid atmosphere.

prompt7 - return to real world

A realistic candid smartphone snapshot captures a young Latina woman in the exact frozen moment of stumbling out of a dimensional portal embedded in an old brick wall on an ordinary city street at night. She is caught halfway between two worlds, with her upper body and one leg already outside in the realistic nighttime street while her other foot is still partially inside the glowing dimensional opening behind her, making it clear that she is still emerging from the portal. Her body is tilted forward as she loses balance, one knee bending, one hand reaching instinctively toward the pavement, and her hair and clothing naturally moving from the sudden motion. The image feels like an accidental phone photo taken by a random passerby at the precise wrong moment, with imperfect timing and no professional composition.

She has a smooth warm light tan complexion, almond-shaped dark eyes enhanced with dramatic smoky eye makeup and winged eyeliner, softly arched brows, defined cheekbones, a narrow jawline, a slender nose, and glossy pink lips. Her medium-long dark chocolate brown shag haircut with layered texture and soft curtain bangs is slightly disheveled from movement, with realistic individual strands, natural volume, and loose strands falling across her face. Her physique is lean yet distinctly curvy, featuring a prominent bust, narrow ribcage, slim waist with subtle oblique definition, toned abdomen, wide rounded hips, full thighs, and athletic feminine arms. She wears a fitted black long-sleeve collared dress with a crisp white pointed collar and white French cuffs, a tailored waist, matte black opaque tights, and black leather lace-up ankle boots. A chunky silver skull ring, stacked black leather wristbands, and a detailed black-and-gray thorned rose vine tattoo wrapping around her right forearm are clearly visible. Her fingernails are painted glossy deep red.

The real-world environment is a completely ordinary urban night street with an old brick building wall, concrete sidewalk, parked cars, streetlights, faded graffiti, utility fixtures, and everyday city details. The photograph has the imperfect qualities of a random smartphone capture: slightly uneven exposure, low-light digital noise, mild motion blur, imperfect focus, accidental framing, subtle smartphone lens distortion, compressed image texture, and no cinematic lighting, no studio setup, no professional photography aesthetic.

The dimensional portal is not a clean sci-fi doorway but a mysterious vertical tear in the brick wall surrounded by soft glowing edges and a diffused luminous boundary. The transition between dimensions is blurred and unstable, with semi-transparent energy distortion, flickering light spill, and a hazy glow that fades naturally into the surrounding air. The brick texture around the opening appears slightly warped by the energy field, while colorful light from the other dimension spills onto the pavement and the woman's clothing.

Inside the portal, a fully animated Simpsons-style world is visible, showing a bright yellow cartoon Springfield environment with simplified buildings, colorful streets, exaggerated cartoon characters, bold black outlines, flat colors, and classic 2D television animation aesthetics. The contrast between the realistic nighttime street and the impossible animated universe inside the portal is clearly visible. The image captures the split-second moment of a real person physically crossing out of a Simpsons cartoon world into reality, accidentally frozen by a casual smartphone camera.

There is quite clear difference in image fidelity (ideogram4) while it takes damn too much longer.

Imo, krea2 should be convenient in most cases.

I didn't like how much time it took for the prompt enhancement step with local llm, so I tried free online chatbots to see if it will help. The actual render time of course reduced from about 1 min to only 10 secs, because I have removed the local llm nodes from the workflow.

First instruction was

>"Read the following guideline and wait for my input."

Then I copy-pasted the following guideline from the comfy template,

>You are an expert prompt engineer for text-to-image models. Your task is to expand the user's prompt into a highly effective image-generation prompt.

>

>Think step by step about the request before writing the answer:

>- What is the subject and mood?

>- What visual styles, mediums, and lighting options would fit? Consider two or three alternatives and pick the one that best serves the caption.

>- What composition, framing, and grounded details will help the text-to-image model?

>

>Then output a single expanded prompt paragraph.

>

>Follow these rules strictly:

>

>2. **Practical T2I Structure:** Write a prompt that a text-to-image model can parse cleanly. Group subjects with their own attributes and actions. Use grounded phrasing for poses, interactions, and spatial layout.

>3. **Style Planning Stays Internal:** Use your internal reasoning to choose style, medium, framing, and lighting. Do not emit planning tags or wrappers in the visible answer body.

>4. **Text Rendering:** If the user requests visible text, quotes, labels, or typography, specify the exact text clearly and wrap requested words in quotes.

>5. **Avoid Over-Specification:** Do not invent highly specific clothing, colors, materials, or scene details unless the input supports them.

>6. **Structure:** Write one cohesive paragraph after the thinking block. No bullets, JSON, or markdown.

>7. **Respect Existing Detail:** If the user's prompt is already detailed, lightly polish and finalize rather than heavily expanding — preserve their phrasing and direction.

>8. **Respect the Human Form:** Treat depictions of people with dignity. Assume clothing covers genitals and intimate anatomy.

>9. **Preserve User Medium:** When the user explicitly requests a medium (e.g. "photo of", "photograph of", "illustration of", "painting of", "sketch of", "3D render of"), honor it. Do not pivot to a different medium to avoid difficulty — match the user's stated intent.

And provided my original text input to three different chatbots,

>"a female contemporary dancer focused on dancing, Contrapposto pose, body contorted, wide angle, wide angle, one hand outstretched mid-dance towards the camera, her face turned away from the camera, high contrast"

The answers from chatbots were:

>GPT-5.5 (Free): A dynamic wide-angle photograph of a female contemporary dancer captured mid-performance in a dramatic contrapposto pose, her body deeply contorted with expressive tension and fluid movement, one hand outstretched toward the camera creating strong foreground perspective and foreshortening, her face turned away from the camera to emphasize the sculptural lines of her body rather than facial expression, the composition centered on the physicality and motion of the dance, an immersive ultra-wide perspective that heightens depth and dynamism, high-contrast lighting that accentuates muscle definition, silhouette, and form, crisp motion frozen at the peak of the movement, cinematic fine-art dance photography with a clean, uncluttered composition.

>Gemini 3.5 Flash (Free): A high-contrast, wide-angle photograph of a female contemporary dancer captured mid-dance, her body contorted in an expressive contrapposto pose. One of her hands is dramatically outstretched directly towards the camera, creating a powerful sense of depth, while her face is turned completely away from the lens. The dramatic lighting emphasizes the sharp contrast between highlights and deep shadows, defining the fluid lines and dynamic tension of her form within the wide framing of the scene.

>Sonnet 4.6 (Free): A female contemporary dancer captured mid-performance in a wide-angle shot, her body in a dynamic contrapposto stance with spine twisted and torso contorted in fluid motion. One arm fully outstretched toward the camera, hand reaching into the foreground and appearing enlarged by the wide-angle perspective, while her face is deliberately turned away from the lens, emphasizing anonymity and pure movement. Her weight shifts asymmetrically, one hip raised, limbs in expressive tension. Shot in a dark studio environment with dramatic high-contrast chiaroscuro lighting — a single strong side light carving sharp highlights across her shoulders, extended arm, and bent limbs against deep shadow. The wide-angle lens distorts space subtly, pulling the viewer into the motion. Fine art dance photography aesthetic, cinematic black and white tones, sharp focus on the outstretched hand with natural depth falloff toward the body.

I thought it might be a useful way for some. I personally like gpt writings for image prompts? Somehow more dynamic feeling

Works great out-of-the-box without any loras or prompt enhancement.

Hope they release the editing model.
