Recraft: Recraft V4 Pro Vector

Recraft V4 Pro Vector generates editable SVG artwork for detailed compositions, logos and illustration. It is the Pro vector edition of V4, supporting text-to-image generation briefs and separate image-to-image workflows without assigning raster pixel sizes to SVG.

About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

Recraft V4 Pro Vector is the Pro SVG model in Recraft’s V4 generation. The family focuses on visual judgement, coherent colour relationships, composition and detailed interpretation of a creative brief. The Pro branch is positioned for finer detail and more demanding compositions, while this Vector edition supplies editable SVG artwork. It is useful for a graphic illustration, emblem or lettering concept that needs a vector working file for later design adjustments.

The exact model code is recraftv4_pro_vector. It is distinct from standard V4 Vector, the raster V4 Pro model and the later V4.1 family. The producer size reference states that all vector models accept fourteen aspect ratios as width-to-height ratios and that SVG output has no fixed pixel size. V4 Pro’s 2048 × 2048 raster dimensions are therefore not a pixel-resolution limit for this edition. Choose the intended composition and shape of the asset rather than a raster-size label.

The manufacturer’s V4 guidance emphasises flat graphic logic for vector and logo work. Describe the graphic type, geometry, silhouette, line discipline, palette and layout. For a harbour emblem, request a detailed graphic with a compact lighthouse silhouette, a large wave shape, generous internal gaps and two flat colours. Specify which element should dominate and which details should remain secondary. Structural description is more useful for an editable vector result than photographic texture or material language when the design should remain flat.

The current exact generation reference supports prompts up to 10,000 characters, one to six outputs, a random seed and preferred-colour or background-colour controls. Optional compatible custom styles and reference images can establish a repeated visual treatment. Flexible matching allows a looser reading and precise matching follows the style more closely. Use visually consistent references and keep the intended colour system explicit; exact reference colours are not guaranteed. For reference-style generation, use one to ten PNG, JPG or WebP images, no more than 64 MB in total and under 20 MB each. Each reference needs a shortest side of at least 256 pixels, a longest side of no more than 4,096 pixels and a resolution of no more than 16 megapixels. Use either these references or a compatible saved style, rather than both.

Recraft documents image-to-image for V4 raster and vector models. Supply an existing image and describe the desired change, with strength from 0 to 1 determining how far the generated result moves from the source. A vector model returns SVG. This operation does not accept V4 style controls, so it differs from creating a new graphic with a style reference. Its image-input requirements allow PNG, JPG, WebP or SVG under 20 MB, up to 16 MP, with sides between 256 and 4096 pixels.

V4 does not support the V3 controls negative_prompt, curated style names, text_layout, artistic_level or no_text. Its manufacturer guidance describes readable short and medium-length phrases when hierarchy is specified, but exact typography still needs inspection in the finished SVG. Check the silhouette, lettering, colour regions and fine details at the intended size, then reshape or recolour the asset as the design requires. This is a detailed vector-generation edition, with its own output and controls rather than the raster Pro model’s properties.

Through Ailoot, select this exact model ID in /v1/images/generations and supply the creative prompt. Retain every returned data entry, whether the response carries a URL or encoded image content, and save the actual bytes with their returned content type. Keep usage and any media task_id with the asset, then review its shapes, lettering and colour regions in the intended design.

Pricing

How the final charge is calculated

The displayed rates estimate the cost before generation. The final charge is calculated from the cost recorded for the original generation. Measured output duration and forecast quantities are not the final billable quantity.

Tariff references do not add request options. Supported parameters are listed for the selected method.
