--- title: Prompting Recraft V4 Styles — Recraft V4 Styles | Runware Docs url: https://runware.ai/docs/models/recraft-v4-styles/guides/prompting description: "How to prompt Recraft V4 Styles: how references pin the style, what the prompt controls, dimensions, and patterns for consistent output." --- ### [Introduction](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#introduction) Recraft V4 Styles is a text-to-image model built around **reusable style consistency**. Attach one to ten reference images and every generation after that holds the same visual language, down to line quality, palette, texture, and rendering character. There is no LoRA training or fine-tuning step. The style is built from the references on the first generate call and returned as a `styleId` you can reuse for every subsequent call. The hero below was generated using the four editorial illustrations under it as references. **The subject is one the model had never seen in those references**, but the ink line, muted earth-tone watercolor palette, and pencil crosshatch shading carry through cleanly. ![Editorial magazine illustration of an astronaut in a white spacesuit floating in orbit above Earth, holding a small potted green seedling in gloved hands, with the blue curvature of Earth and a scattered star field visible behind](https://runware.ai/docs/assets/hero.CQqQ1euO_Z1t7uuJ.jpg) > **Prompt**: An astronaut in a white spacesuit floating in weightless orbit above Earth, holding a small potted green seedling in gloved hands, Earth's blue curvature and star field visible behind. Wide portrait framing, small figure against vast space, cinematic composition. Editorial magazine illustration style. **Chef**: ![Editorial magazine illustration of a chef in whites sautéing vegetables in a busy restaurant kitchen, bold black ink line work, muted earth-tone watercolor fills, pencil crosshatch shading](https://runware.ai/docs/assets/source-ref-chef.B1JVP6l-_Z1Y7SR2.jpg) > **Prompt**: Editorial magazine illustration, bold black ink line work with muted earth-tone palette (terracotta, sage green, cream, deep navy), textured watercolor fills with visible paper grain, pencil crosshatch shading, of a chef in whites sautéing vegetables in a busy restaurant kitchen.

New Yorker or The Atlantic editorial aesthetic. **Pianist**: ![Editorial magazine illustration of a pianist playing a grand piano in a small warmly lit concert hall, bold black ink line work, muted earth-tone watercolor fills, pencil crosshatch shading](https://runware.ai/docs/assets/source-ref-musician.CXybD3T__Z19Tg3a.jpg) > **Prompt**: Editorial magazine illustration, bold black ink line work with muted earth-tone palette (terracotta, sage green, cream, deep navy), textured watercolor fills with visible paper grain, pencil crosshatch shading, of a pianist playing a grand piano in a small warmly lit concert hall. Simple neutral background. New Yorker or The Atlantic editorial aesthetic. This guide covers the request shape, the two ways to pin a style (direct references or a reusable style ID), how the prompt and the references split the work, the dimensions the model ships at, and the patterns worth internalising. ### [Request shape](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#request-shape) Every V4 Styles request needs a `positivePrompt` and either `inputs.referenceImages` or `inputs.styleId`. **The two are mutually exclusive per request.** Pass `width` and `height` from the fixed pixel-pair list. Nothing else is required.

The choice is about **when the style gets built**. **Direct references.** Attach `inputs.referenceImages` on a fresh call. The model reads the references, builds the internal style representation, and generates in that style. The response returns a `styleId` you can keep for later use. Reach for this on the first call of a new style pipeline, or for one-off generations where you know you won't need the style again. **Reusable style ID.** Pass `inputs.styleId` on the call. The model applies the already-built style directly, skipping the reference-read step. Faster than re-uploading references on every call, and the ID is portable within its family (raster IDs across `styles` and `styles-pro`, vector IDs across `styles-vector` and `styles-pro-vector`). Reach for this on any pipeline that generates many images in one style. The four references shown alongside the hero at the top of this guide are all editorial illustrations in the same style with different subjects. The model reads them together as one style, extracting what they share. Style references **can come from anywhere the model can fetch**: prior Runware generations, other model outputs, brand or campaign assets, scans of physical art, editorial imagery from a client library. Each image must be at least 256 × 256 pixels and no larger than 10 MB, and the combined attachment for a single request cannot exceed 64 MB. ### [What the prompt does](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#what-the-prompt-does) The `positivePrompt` describes **the subject and the shot**: who or what is in the image, the action, the composition, the framing. It does not need to describe the style, because the references already do. A style-consistent generation with V4 Styles is a **split of labour**. References pin the look, the prompt names the content. That split changes how the prompt should be written compared to a plain text-to-image call. The four techniques below cover most of what makes a V4 Styles prompt land. #### [Name the subject and the action](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#name-the-subject-and-the-action) Vague subjects get generic output. "A person at a desk" gives a person of the model's choosing at a desk of the model's choosing. **The extra words are not decoration, they are the difference between the model inventing the scene and the model rendering yours.** Pin the age, distinctive features, wardrobe, and the specific props in the frame. "A woman in her forties with grey hair in a low bun at a warm walnut desk with two laptops and a small potted succulent" leaves the model far less to invent. **Action verbs tighten the moment.** "A woman at a desk" gets a static portrait. "A woman leaning forward and typing" gets action. "A woman leaning forward, half-standing to reach for a paper on the far side of the desk" gets a specific instant. The more specific the verb, the less the model has to guess about the pose. #### [Name the composition and framing](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#name-the-composition-and-framing) Composition and framing words are **first-class directives**. Reach for these consistently: - **Framing size**: extreme close-up, close-up, mid-shot, chest-height mid-shot, wide, wide establishing shot - **Camera angle**: eye level, low angle looking up, high angle looking down, three-quarter angle, overhead - **Subject placement**: centred, small figure against a vast sky, off to the left, close to the frame edge, occupying the lower third - **Depth of field**: shallow with the subject in sharp focus, deep with everything crisp, foreground element blurred The hero above uses "wide portrait framing, small figure against vast space, cinematic composition" to place the astronaut small in a large frame. **Without those words, the model would default to a closer, more centred crop.** #### [Don't describe the style](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#dont-describe-the-style) Style words in the prompt compete with the references. A prompt like "an editorial illustration with bold black lines and muted earth-tone watercolor fills of a hiker at sunrise" tells the model two things at once: match the references, and match the words. When the words disagree with the references in any detail, the output drifts. **Drop the style words.** The prompt becomes shorter, the model reads it cleaner, and the output stays inside the reference world. The two outputs below use the same four references as the hero. Neither prompt names the style. Both describe only the subject, the setting, and the shot. ![Editorial magazine illustration of a lone hiker with a red backpack standing on a rocky mountain ridge at sunrise, looking down at a valley of pine trees wrapped in morning mist, warm golden light on the peaks](https://runware.ai/docs/assets/output-hiker.v8-m17GG_1osquD.jpg) *Same reference style, mountain-ridge subject* > **Prompt**: A lone hiker with a red backpack standing on a rocky mountain ridge at sunrise, looking down at a valley of pine trees below wrapped in morning mist. Wide landscape framing, small figure against vast sky, warm golden light on the peaks. Editorial magazine illustration style. ![Editorial magazine illustration of a bustling outdoor farmers market at midday, wooden stalls with baskets of tomatoes, peaches, and fresh herbs, a young woman shopper in a linen dress examining a tomato while the vendor smiles from behind the stall](https://runware.ai/docs/assets/output-market.CtEQ2xVi_YMYNM.jpg) *Same reference style, market-scene subject* > **Prompt**: A bustling outdoor farmers market at midday, wooden stalls with baskets of ripe tomatoes, peaches, and fresh herbs, a young woman shopper in a linen dress examining a tomato while the vendor smiles at her from behind the stall. Chest-height framing, warm midday sun overhead. Editorial magazine illustration style. Both hold the reference style down to the specific ink treatment and colour palette. **Every element the prompt names appears in the output**, but the visual language stays inside the reference world. #### [Name specific characters](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#name-specific-characters) When a specific person or character needs to render (a spokesperson, a recurring illustrated character, a named subject in an editorial piece), name them with enough detail to pin their identity: age, hair length and colour, distinctive features, wardrobe. "A woman in her thirties with short blonde hair and wire-frame glasses in a cream sweater" pins the subject in a way "a woman at a desk" cannot. For character consistency across many generations, **keep the same identity clause across every prompt** so the model's read of the character stays stable. ### [Iteration workflow](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#iteration-workflow) A prompt rarely lands right on the first pass. The pattern for V4 Styles is to **keep the reference set constant and change only the prompt**, so each iteration isolates one variable and the style holds throughout. **Pass 1, establish the subject.** Start with the smallest prompt that names the subject and the setting. Read the output. If the subject is wrong (wrong person, wrong object, wrong environment), fix that before touching anything else. **[Subject]** A remote worker at their desk ![Editorial magazine illustration of a person seated at a desk with a laptop in a neutral workspace](https://runware.ai/docs/assets/output-iteration-1.CTji8qFO_Z1TW1Sr.jpg) *Pass 1 output: subject named, everything else on defaults* > **Prompt**: A remote worker at their desk. **Pass 2, pin the character and props.** If the subject is right but the details are off (wrong age, wrong clothes, wrong specific objects), name them. Age, hair, wardrobe, and named props. **[Subject]** A woman in her forties with grey hair in a low bun, **[Wardrobe]** wearing a soft cream sweater, **[Setting]** at a warm walnut desk with two laptops and a small potted succulent, **[Lighting]** warm morning light through a window on the left ![Editorial magazine illustration of a woman in her forties with grey hair in a low bun and a cream sweater, at a warm walnut desk with two laptops and a small potted succulent, warm morning light from a window on the left](https://runware.ai/docs/assets/output-iteration-2.hCEEd0M8_Z1NiOol.jpg) *Pass 2 output: specific character and named props, framing still generic* > **Prompt**: A woman in her forties with grey hair in a low bun, wearing a soft cream sweater, at a warm walnut desk with two laptops and a small potted succulent, warm morning light through a window on the left. **Pass 3, direct the shot.** If the subject reads correctly but the framing or composition is generic, add camera direction. Framing size, angle, subject placement, depth. **[Subject]** A woman in her forties with grey hair in a low bun, **[Wardrobe]** wearing a soft cream sweater, **[Setting]** at a warm walnut desk with two laptops and a small potted succulent, **[Lighting]** warm morning light through a window on the left, **[Camera]** chest-height mid-shot, camera slightly angled from the left, **[Depth]** shallow depth of field with her hands and the closer laptop in sharp focus ![Editorial magazine illustration of a woman in her forties with grey hair in a low bun and a cream sweater at a warm walnut desk with two laptops and a small potted succulent, chest-height mid-shot camera slightly angled from the left, shallow depth of field with her hands and the closer laptop in sharp focus](https://runware.ai/docs/assets/output-iteration-3.BUo_rSaY_ZhkUH4.jpg) *Pass 3 output: subject, props, and shot direction all locked* > **Prompt**: A woman in her forties with grey hair in a low bun, wearing a soft cream sweater, at a warm walnut desk with two laptops and a small potted succulent, warm morning light through a window on the left. Chest-height mid-shot, camera slightly angled from the left, shallow depth of field with her hands and the closer laptop in sharp focus. Each pass **changes one dimension**. The reference set stays the same across the three, so the style stays constant while the reader can see prompt refinement shifting the output shape only. Once a prompt lands, its structure often carries to the next subject: swap the subject clause, keep the composition clause, keep the depth clause. ### [Common failure modes](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#common-failure-modes) Four patterns cause most V4 Styles outputs to miss. - **Style words competing with references.** The prompt names the style ("bold black lines, muted watercolor palette") on top of references that already have it. The model reads both, they disagree in some small detail, and the output drifts. Fix: drop the style words. The references carry the style. The prompt only describes what's happening in the image. - **Vague subject or ambiguous action.** "A person doing something" leaves too much for the model to fill in. Fix: name the subject specifically (age, wardrobe, distinctive features) and the action concretely with a verb plus an object. - **Missing camera direction.** Without framing or angle words, the model picks a default that varies from run to run. Fix: name the framing (wide, mid-shot, close-up), the angle (eye level, overhead, three-quarter), and where the subject sits in the frame. - **Over-long prompts.** Piling on forty adjectives past the useful ones dilutes the model's attention. The most concrete beats near the front land best. Softer clauses drop out. Fix: cut anything that isn't a subject, action, prop, camera, or setting cue. Style words go first (see above), then any adjective that doesn't change what appears on screen. When a first render is close but wrong in one specific way, **iterate that specific miss** using the pattern above. Rewriting the whole prompt usually swaps one problem for another. ### [Reusing the style ID](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#reusing-the-style-id) Once a request returns a `styleId`, later calls skip the reference upload: TypeScriptPythoncURLCLIJSON ```typescript import { createClient } from '@runware/sdk' const client = await createClient({ apiKey: process.env.RUNWARE_API_KEY }) await client.connect() const [result] = await client.run({ model: 'recraft:v4@styles', positivePrompt: 'A woman on a subway platform late at night, holding a warm coffee cup in both hands, reading a book, empty tiled tunnels stretched behind her, single overhead station light.

Chest-height framing, muted ambient light. Editorial magazine illustration style. A style ID belongs to your workspace and **persists indefinitely**. Store it alongside the assets you generate so downstream pipelines can pick up the same look without needing the source images. The ID is portable **within its family**. A style built with `recraft:v4@styles` (1K raster) can drive `recraft:v4@styles-pro` (2K raster) from the same UUID, and a style built with `recraft:v4@styles-vector` (1K SVG) can drive `recraft:v4@styles-pro-vector` (2K SVG). The ID does not cross the raster and vector boundary. To get both formats from the same reference set, build a raster style and a vector style separately from those references. ### [Dimensions](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#dimensions) Set `width` and `height` from the model's fixed pixel-pair list. Fourteen pairs cover the common aspect ratios at the 1K tier for `styles` and the same aspects at 2K for `styles-pro`. **Pick by delivery target**: landscape 3:2 or 16:9 for landing heroes and article banners, square 1:1 for social feeds, portrait 2:3 or 9:16 for stories and vertical placements. See the [Recraft V4 Styles model reference](https://runware.ai/docs/models/recraft-v4-styles) for the full pixel-pair list. Aspect is **per-call, not per-style**. A style built from portrait references still renders landscape or square outputs when a later call specifies those dimensions. Match the aspect to the delivery target, not to the reference set. For SVG output, use `recraft:v4@styles-vector` or `recraft:v4@styles-pro-vector` with `taskType: "vectorize"`. A style ID from any raster variant works with the other raster variant, and a style ID from any vector variant works with the other vector variant. Style IDs do not cross the raster and vector boundary. ### [Real use cases](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#real-use-cases) Three concrete deliverables that fit the "one style, many outputs" pattern V4 Styles is built for. All three outputs below use the hero's four references, only the prompt and dimensions change. #### [Editorial illustration for an article header](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#editorial-illustration-for-an-article-header) Magazines and newsletters ship article-by-article illustrations that must **all look like they came from the same publication**. The pattern: pick or build a reference set once, save the returned `styleId`, and generate a fresh illustration per article prompt. Article headers, in-line spot illustrations, and social-share cards all draw from the same style ID. Prompt shape: describe the concept the article covers (the subject and the setting), name the framing for the placement (landscape banner for the header, square for social), skip the style. ![Editorial magazine illustration of a vast open-plan office at dusk with rows of empty desks and a single person still working at a distant desk under a warm task lamp, city lights visible through floor-to-ceiling windows behind](https://runware.ai/docs/assets/output-usecase-editorial.CBwMy1uu_Z4Fp1k.jpg) *Article header for an editorial piece on late-night knowledge work* > **Prompt**: A vast open-plan office at dusk with rows of empty desks and a single person still working at a distant desk under a warm task lamp, the glow of city lights visible through a wall of floor-to-ceiling windows behind them. Wide establishing shot, small figure against the empty office, cool blue evening light outside contrasting with the warm pool of lamp light on the working desk. #### [Ad hero for a subscription product](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#ad-hero-for-a-subscription-product) A single ad campaign often ships in ten to fifty variations across placements: hero banner, side rail, mobile interstitial, social feed, story frame. **Same style ID, different width and height per placement**, different prompt per variation. Prompt shape: keep the brand's tone consistent by using the same character identity across variations (if there's a spokesperson), vary the situation and setting per placement. ![Editorial illustration of a young reader in a cream sweater curled up in a warm overstuffed reading chair by a large window, engrossed in a thick hardcover novel, a stack of unopened books on the floor beside the chair, autumn leaves outside the window](https://runware.ai/docs/assets/output-usecase-book.BX3fJQYR_2iqThl.jpg) *Portrait ad hero for a book-subscription campaign* > **Prompt**: A young reader in a soft cream sweater curled up in a warm overstuffed reading chair by a large window, engrossed in a thick hardcover novel, a small stack of three unopened books on the floor beside the chair, autumn leaves visible outside the window, warm evening lamp light. Portrait framing, chest-height angle, shallow depth of field with the reader in sharp focus. #### [Marketing hero for a product landing page](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#marketing-hero-for-a-product-landing-page) Product marketing pages want a hero illustration that **matches the rest of the site's visual system**. The pattern: use the site's illustration system's reference set, generate the product-specific hero, drop it into the page. When the illustration system evolves (new palette, new rendering), rebuild the style from an updated reference set and regenerate the hero without touching the prompt. ![Editorial illustration of a calm remote worker with grey hair in a low bun at a spacious walnut desk with two laptops open showing dashboards, a large paper sketch pad and pen, a ceramic mug of steaming coffee, a low potted succulent, natural morning light through a large window](https://runware.ai/docs/assets/output-usecase-saas.HkX7QUeW_Z2sw2vo.jpg) *Landing-page hero for a remote-work SaaS product* > **Prompt**: A calm remote worker in her forties with grey hair in a low bun at a spacious warm walnut desk, two laptops open side by side showing subtle dashboards, a large paper sketch pad and pen beside them, a small ceramic mug of steaming coffee, a low potted succulent to her left, natural morning light through a large window on the right. Chest-height mid-shot, camera slightly angled from the left, shallow depth of field with her hands and the closer laptop in sharp focus. ### [Tips](https://runware.ai/docs/models/recraft-v4-styles/guides/prompting#tips) 1. **Write the prompt as if the style were implied.** References pin the look. The prompt names the subject and the shot. Style words in the prompt can compete with the references, so drop them. 2. **Attach one to ten references.** A single strong reference is enough to lock in a style. Multiple references reinforce the shared elements between them, and give the model more angles on the style. 3. **Store the `styleId` from the first response.** Later calls skip the reference upload and use the ID directly. Faster and cheaper for bulk work. 4. **A style ID is portable within its family.** Raster style IDs work with `styles` and `styles-pro`. Vector style IDs work with `styles-vector` and `styles-pro-vector`. Style IDs do not cross the raster and vector boundary. To ship both formats from one reference set, build a raster style and a vector style separately. 5. **Pick a pixel pair, don't invent one.** Only the fourteen listed dimensions validate. Anything else fails. 6. **The style match mode defaults to precise.** V4 Styles follows the reference style meticulously by default. Setting `settings.styleMatch: "flexible"` loosens that match, closer to the V3 experience.
