The short answer

Write FLUX prompts as natural English sentences rather than lists of tags. Go in the order subject and action, look, composition, place, light, art style, and describe the state you want instead of what you do not want. Put short text in quotation marks to render it.

Tags or sentences for FLUX prompts?

Natural English sentences are the default. Joining who is doing what and where into sentences makes your intent clear.

FLUX is known as an image model with a strong understanding of text. So instead of listing tags like "1girl, long hair, smile", a sentence like "A girl with long hair smiles at the viewer" carries positions and relationships (who is doing what) better. There are several model variants and tools, and the rules can change, so check the documentation of the environment you use.

Aspect	Tag-based (SD anime models)	FLUX (natural English)
How you write	Words separated by commas	Connected sentences
Positions and relationships	Hard to express	"On the left", "holding" come across well
Quality tags	Often include masterpiece and similar	Often not needed
Negative prompts	Used a lot	Depends on the environment, may not work well
Text in images	Weak	Often good with short text

What order should a FLUX prompt follow?

Subject and action, then look, composition, place, light and art style is an easy order to manage.

Steps to build a FLUX prompt in English

Write the subject and what they are doing in one sentence
Write the look (hair, eyes, outfit) in a second sentence
Write the composition (where it is seen from and how big)
Write the place and the things around it
Write the light and time of day (evening, backlight and so on)
Finally, write one art style (anime illustration, watercolor and so on)

A young woman with long black hair and red eyes sits by a large window, looking outside with a calm smile. She wears a cream knit sweater and a red ribbon in her hair. Medium shot from the waist up, eye-level. A small quiet cafe with wooden tables and plants. Soft afternoon light from the window. Anime style illustration with soft colors.

A girl in a white sailor school uniform walks along a riverside path lined with cherry blossom trees, petals drifting in the wind. Wide full-body shot from a low angle. Clear blue sky, bright spring morning light. Clean anime illustration with crisp lines.

Illustration usage rules

What works well and what does not

Style of writing	How well it works	Notes
Specific colors and objects (a red ribbon in her hair)	Works well	Pair the color with where it is
Actions as sentences (she holds an umbrella)	Works well	Carries relationships better than tags
Elements written early	Work strongly	Put important things first
Negative sentences (no hat)	Weak	Describe the state you want (bare head, etc.)
(word:1.5) emphasis	Does not work in some environments	Use wording (vivid, soft) for strength
Many style words	Tends to get muddy	Narrow it to one style

Rinka's tips

Write what should happen, not what should not. If you do not want a hat, do not mention hats; describe the hairstyle instead
Longer prompts pin down more detail, but keep the important elements in the first half
Do not repeat the same meaning. Saying it clearly once is enough

How do you put text in an image with FLUX?

Put the short text in quotation marks and say where it is written.

FLUX is known as relatively good at rendering short text inside images. Put the text in quotation marks and say where it appears (a sign, a T-shirt, a book cover). Long sentences and small text go wrong more often, so start with short words.

A cozy bakery storefront with a wooden sign that reads "BAKERY" in white hand-painted letters, a girl with a red ribbon standing beside the door and smiling, warm morning light, anime style illustration.

Unwanted things appear or it looks like a photo? (FLUX fixes)

The usual causes are negative sentences and a weak art style description.

Problem	Cause	Fix
A tag list gave the wrong result	Relationships between tags were lost	Make it a sentence connecting who, what and where
It looks like a photo	Weak style word, or placed too late	Write anime style illustration and remove realistic words
Unwanted things appear	Written as negatives	Drop the negatives and describe the state you want
Part of the prompt is ignored	Too many elements	Narrow to the three or four that matter and put them first
The text is wrong	The text is long	Use short text in quotation marks

Examples: turning tags into English sentences

Tags	Sentence	Point
1girl, solo	A girl	The number of people becomes the subject
long hair, black hair, red eyes	with long black hair and red eyes	Group them with "with"
holding umbrella, rain	holds an umbrella in the rain	Actions become verbs
from below, full body	Wide full-body shot from a low angle	Composition in one sentence
sunset, backlighting	warm sunset light from behind her	State the direction of the light
