Choosing an image model in Alberti Studio

Alberti Studio gives you a long list of image models. That is a gift and a problem at the same time. This guide is the map: what each one is actually for, where each one struggles, and how to stop guessing. It covers the models made by other labs. Our own models, Hamilton, Photo Pilot, Quantum, Selena and Selena Variété, get a post of their own, and so do the video models. Both are coming soon.


Start here: there is no best model

Every comparison table you will ever read, including the ones below, hides the same truth. There is no model that wins at everything. Each one has a shape. One is better at text inside the picture, another at skin and light, another at editing something you already made, another at being fast enough to try twenty ideas before lunch.

So the question is never “which is the best model.” It is always “what is this particular job asking for.” Once you ask it that way, the choice gets easy, and most of the time it comes down to four or five models you will end up using again and again.

The fastest way to learn all of them

Take one prompt you know intimately. Something you have run many times and whose result you can picture with your eyes closed. Run it unchanged through four different models. Do not fix it between runs, do not adapt it to each model, do not help.

Ten minutes of that will teach you more than any table, because you already know what the prompt is supposed to produce. The differences will not be abstract. They will be the gap between what you expected and what came back.

Do this before you read the rest of this guide. Everything below will land better afterwards.

We tried it ourselves. One prompt, eight models:

Image models

Grouped by the job, not by the company that made them.

The everyday workhorses

Flux 2 Pro

Best at: photorealism with the details that usually give AI away, hands, faces, fabric, skin. Strong prompt adherence, good text rendering, and it accepts up to eight reference images for editing. Output up to 4 megapixels at any aspect ratio.

Watch out for: 4 megapixels is the ceiling. If you need a bigger file, for print for example, upscale it afterwards.

Reach for it when: you do not have a specific reason to reach for something else. This is the sensible default for photographic work.

Close-up of an elderly potter's clay-covered hands shaping a terracotta bowl on a spinning wheel, a frayed linen apron behind
Wrinkled knuckles, wet clay and the frayed weave of the apron, all sharp in one close-up.
See the prompt
Close-up photograph of an elderly ceramicist's hands shaping a wet clay bowl on a spinning potter's wheel, slip running between wrinkled fingers, fine clay dust on the forearms, a frayed linen apron with visible weave. Soft north-window light from the left, shallow depth of field, 85mm lens at f/2. Warm earthy palette, terracotta #B5603A clay, natural skin texture.

Seedream 4 and Seedream 4.5

Best at: generating and editing in one model, at up to 16 megapixels (roughly 4K), and doing it fast. Version 4.5 is the one to prefer: it was rebuilt around editing consistency, meaning it holds a face, a lighting setup and a colour palette steady when you change something else. It also handles dense small text and mixed Chinese and English layouts, which is why it ended up popular for posters and product listings.

Watch out for: no mask-based inpainting. You describe the change in words rather than painting a region. And version 4.5 starts at 4 megapixels, so it is not the one for small, quick drafts.

Reach for it when: you have an image already and want to change part of it without the rest drifting.

A woman in a beige suit on a sunny city streetOriginal
The same woman and street, now in a mustard yellow raincoatEdit 1: the jacket
The same woman in the yellow raincoat, now with rain and wet reflections on the streetEdit 2: the weather
Two edits in a row. The jacket and then the weather change, while her face, hair and pose stay the same.
See the prompt
Edit 1: Change only her jacket to a mustard yellow raincoat. Keep her face, hairstyle, expression, lighting and background exactly the same.

Edit 2 (on the result of edit 1): Now add light rain and wet reflections on the street behind her. Keep her face, the raincoat and the lighting on her exactly the same.

Nano Banana 2

Best at: text inside the image, including translating text between languages, and something none of the others do as well: it can search the web while generating. Ask for something time-sensitive or factual and it can look it up rather than inventing it. In Alberti Studio you turn this on with the Google Search switch in the settings. Output at 1K, 2K or 4K, and it holds characters and objects consistent from reference images.

Watch out for: every output carries an invisible SynthID watermark. Google’s own documentation says it is not optimised for many reference images or long back-and-forth editing sessions.

Reach for it when: the picture has to contain correct words, or has to reflect something real.

The same chalkboard with the menu translated into English A café chalkboard menu written in Hungarian HungarianEnglish
Drag the handle. The menu was translated on the board itself, with the same handwriting, prices and doodles.
See the prompt
Step 1: A café chalkboard menu on a brick wall, hand-written in white chalk, in Hungarian: "MAI AJÁNLAT", "Sütőtökkrémleves – 1 490 Ft", "Rántott sajt – 2 290 Ft", "Almás pite – 990 Ft", small chalk doodles of a cup and a leaf in the corners.

Step 2: Translate all the text on the chalkboard into English. Keep the handwriting style, the prices, the layout and the doodles exactly the same.
A vintage-style illustrated postcard of the Votive Church in Szeged, with a caption saying its construction was completed in 1930
With Google Search switched on, it looked up when the Votive Church in Szeged was finished and put the correct year, 1930, on the card.
See the prompt
An illustrated vintage postcard of the Votive Church in Szeged, Hungary, with accurate architecture, and a small caption giving the year the church was completed.

Settings: Google Search on.

When the image has to carry text or structure

Flux 2 Flex

Best at: typography and small details. It is the same family as Pro but tuned for text, so pick it when the words in the picture have to come out right, down to the small print. It also lets you type an exact custom size instead of picking a ratio.

Watch out for: like the rest of the Flux family, it ignores negative prompts. Describe what you want to see, not what you want to avoid.

A kraft paper coffee bag on a marble counter with a black printed label reading Ember Roasters, Ethiopia Yirgacheffe, and small print tasting notes, sealed with red wax Close-up of the same label: EMBER ROASTERS, Ethiopia Yirgacheffe, washed · light roast · notes of jasmine, lemon, honey, 250 g
Four type styles on one label, from the bold headline down to the small print, every word spelled as asked. Second image: an unretouched crop of the same image.
See the prompt
Product photo of a kraft paper coffee bag standing on a marble counter. The front label is printed in black ink: the brand name "EMBER ROASTERS" in a bold condensed sans-serif at the top, below it "Ethiopia Yirgacheffe" in an elegant italic serif, a thin line, then small print reading "washed · light roast · notes of jasmine, lemon, honey", and at the bottom "250 g". A small red #C8372D wax seal on the fold. Soft side light showing the paper texture.

GPT Image 2

Best at: the things that are not really pictures. Diagrams, infographics, charts, posters, comics, anything where structure and labels matter as much as the image. Good multilingual text, and it composites several input images sensibly if you refer to them by position and description. It can also return a transparent background, which saves a separate cut-out step for logos, stickers and product shots.

Watch out for: there is no resolution setting. You choose a quality level instead, from low to high, and the higher levels take longer.

Numbered steps, icons, arrows and captions, laid out the way a designer would.
See the prompt
A clean infographic titled "How a Recipe works", four labelled steps from top to bottom connected by arrows: "Prompt", "Text generation", "Flux 2 Flex", "Photo Pilot". Each step has a simple line icon and a one-line caption next to it. Dark charcoal background, warm gold #CF9A52 accents, modern sans-serif, vertical 4:5.

Qwen Image 2

Best at: paragraph-level text. Not a headline or a label, but actual multi-line blocks laid out properly inside the picture. Slides, posters, dense information graphics.

Watch out for: there is no resolution setting, and a square image comes out at 1024×1024, about 1 megapixel. Upscale it afterwards if you need more. It also takes only one reference image.

A printed recipe card for Grandma's Apple Pancakes on a floury wooden counter, with an ingredients list and a method paragraph Close-up of the method paragraph on the recipe card
A title, an ingredients list and a full method paragraph, set like a printed card. Second image: an unretouched crop of the same image.
See the prompt
A printed recipe card lying on a wooden kitchen counter, photographed from above. Title at the top: "Grandma's Apple Pancakes". Left column titled "Ingredients" with the lines: "2 eggs", "250 ml milk", "150 g flour", "1 apple", "1 pinch of salt", "butter for the pan". Right column titled "Method" with the paragraph: "Whisk the eggs and the milk. Add the flour and the salt and stir until smooth. Grate the apple into the batter. Melt a little butter in a hot pan, pour in a small ladle of batter and cook for two minutes on each side. Serve warm with honey." Cream paper, dark brown serif type, a dusting of flour around the card.

Grok Imagine

Best at: laying out a design the way a designer would: a clear hierarchy, a sensible grid and room to breathe. Ask for the same poster in a different aspect ratio and it rearranges the layout rather than just cropping it.

Watch out for: in Alberti Studio the only setting is the aspect ratio, so there is nothing to tune beyond the prompt, and a square image comes out at 1024×1024. And xAI publishes no prompting guide at all, so you are learning by experiment.

The Night of Type poster in a tall 9:16 layout9:16
The Night of Type poster in a square layout1:1
The Night of Type poster in a wide 16:9 layout16:9
One prompt in three aspect ratios. The layout is rebuilt for each format, not cropped.

A modern event poster for a design meetup called "Night of Type", a large bold headline, the date "Oct 24" and the line "Szeged · 7 pm", abstract geometric shapes in coral #F2665A and navy #1B2A4A, generous whitespace, strict grid layout.

Run three times, with the aspect ratio set to 1:1, 9:16 and 16:9.

When you need many tries, quickly

Flux 2 Klein 9b

Best at: speed. It is a small, four-step model built for volume, and it is meant for the part of the process where you are still deciding what you want. In Alberti Studio it goes down to 0.25 megapixels and has a Go fast switch, both handy for quick drafts.

Watch out for: only four reference images instead of eight, and weaker text rendering than its bigger siblings.

A glass globe terrarium on a wooden desk containing a snowy alpine village at night A glass globe terrarium on a wooden desk containing a red desert canyon with a camel caravan A glass globe terrarium on a wooden desk containing a sunken pirate ship on a coral reef A glass globe terrarium on a wooden desk containing a volcano island with glowing lava rivers A glass globe terrarium on a wooden desk containing a Japanese garden with a red bridge and cherry blossoms A glass globe terrarium on a wooden desk containing a neon-lit cyberpunk street in the rain A glass globe terrarium on a wooden desk containing an autumn forest with a river and a wooden mill A glass globe terrarium on a wooden desk containing a lighthouse on a cliff in a storm A glass globe terrarium on a wooden desk containing a floating island with waterfalls pouring into clouds A glass globe terrarium on a wooden desk containing a frozen arctic sea with a research ship and polar bears A glass globe terrarium on a wooden desk containing a medieval castle on a hill at sunset A glass globe terrarium on a wooden desk containing a jungle with a hidden stone temple
One prompt, run twelve times. Only the world inside the globe changes. All twelve took less than a minute in total.
See the prompt
A glass terrarium globe resting on an old wooden desk, holding a complete miniature world inside: [WORLD]. Tiny details visible through the curved glass, soft reflections on the glass, warm desk-lamp light from the side, dark moody background, macro photography, shallow depth of field.

[WORLD] was swapped each time: a snowy alpine village at night, a red desert canyon with a camel caravan, a sunken pirate ship on a coral reef, a volcano island with lava rivers, a Japanese garden, a neon cyberpunk street in the rain, an autumn forest with a mill, a lighthouse in a storm, a floating island with waterfalls, a frozen arctic sea with polar bears, a castle at sunset, a jungle with a hidden temple.

Z Image Turbo

Best at: photorealistic portraits and product shots, generated in a few seconds. A small, fast model that does far better than its size suggests.

Watch out for: the speed has a price. On busy scenes with lots of people or detail, it falls behind the larger models.

A matte black ceramic mug with steam rising, on a light wooden table by a window A pink ceramic mug with steam rising, on a light wooden table by a window A blue ceramic mug with steam rising, on a light wooden table by a window A green ceramic mug with steam rising, on a light wooden table by a window A red ceramic mug with steam rising, on a light wooden table by a window A yellow ceramic mug with steam rising, on a light wooden table by a window
Six colour variants, one after the other. Each one took less than five seconds to generate.
See the prompt
Studio product photo of a plain matte black ceramic coffee mug with a smooth, well-shaped handle, on a light oak table, soft morning daylight from a window, a thin curl of steam rising, minimal composition, plenty of empty space on the right, no text or logo.

For each variant, only the colour changes.

Seedream 5 Lite

Best at: thinking before drawing. It reasons about spatial relationships and physical plausibility, and accepts up to fourteen reference images. It also supports example-based editing, where instead of describing a change you show a before and after pair and it applies the same treatment.

Watch out for: it is the Lite version, so for a polished final image, compare its result with Seedream 4.5.

The whole prompt

“Image 1 and image 2 show a before and after. Apply exactly the same transformation to image 3.”

The prompt never says “watercolour”. The example pair is the only description of the style.

The car and house drawing turned into a watercolour in the same style A black and white line drawing of a car parked in front of a house New drawingResult
Drag the handle. Given only the example pair and a new drawing, it worked out the watercolour treatment and applied it to the car.

When you want the very best single image

Flux 2 Max

Best at: the hardest jobs. Character consistency across a series, product photography, retexturing a surface while keeping its geometry and lighting intact, spatial reasoning.

Watch out for: it costs meaningfully more than Pro. Use it for the final frame, not the twenty before it.

After: the same armchair retextured in worn cognac leather with brass studs Before: a mid-century armchair upholstered in cream and grey fabric BeforeAfter
Drag the handle. Same chair, same camera angle, same afternoon light. Only the material changed.
See the prompt
Keep the exact shape, proportions, camera angle and lighting of the armchair in image 1. Change only its material to worn cognac leather #8B4A2B with soft creases on the seat and a row of small brass studs along the arms.

Wan 2.7 Image

Best at: working from a lot of material. It takes up to nine reference images, so you can combine a product, a person and a place in one picture without describing each of them in words.

Watch out for: you pick the size from a fixed list rather than setting an aspect ratio and a resolution separately, and the largest is 2048×2048, about 4 megapixels. Upscale it afterwards if you need more.

If you remember three things

Pick by the job, not by the ranking. A model that is third overall might be first at the thing you are doing this afternoon.

When you edit, say what must stay the same. Name what to change and what to keep, and repeat it on every round, or the picture slowly drifts away from the one you started with.

Run the same prompt through four models. Not because one will win, but because you will finally know what each of them does with the same instruction. That knowledge is the whole skill.
