Which Youchuan V8.1 API Endpoint Fits Your Workflow
A side-by-side look at every Youchuan V8.1 API modality, from text-to-image and image-to-image to video, blending, style transfer, and background removal.
| Modality | Description |
|---|---|
| Youchuan V8.1 T2I API (Text to Image) | Feed in a text prompt and receive four images per run, with optional native 2K HD output and a style reference for a consistent look. Aspect-ratio, stylize, chaos, and weird parameters fine-tune composition and creative variance, making it a fit for concept art, brand visuals, and fast moodboards at $0.086 per call. |
| Youchuan V8.1 I2I API (Image to Image) | This endpoint re-imagines an existing image under the guidance of a text prompt and returns four distinct variations. Native 2K HD, a style reference, and the same aspect-ratio, stylize, chaos, and weird controls carry over, so it suits iterating on a frame or exploring alternate directions for a design at $0.086 per call. |
| Youchuan V8.1 I2V API (Image to Video) | From a single still image, this endpoint produces four 5-second clips at your choice of 480p or 720p. Four takes per run let you pick the motion that best fits the shot, which works well for social loops, film pre-visualization, and adding subtle movement to static art. |
| Youchuan V8.1 Blend API (Multi-Image Fusion) | When you need to merge references, supply two to five source images and the model fuses them into four combined results at native 2K HD. An optional guiding prompt steers the blend, making the endpoint useful for compositing, mood mixing, and unifying disparate inputs into one frame, all at $0.086 per call. |
| Youchuan V8.1 Style Transfer API (Image Retexture) | Want a new look without losing your layout? This retexture endpoint restyles an input image while preserving its composition and returns four variations, fitting rebranding passes, art-direction tests, and giving a photo set a shared aesthetic at $0.129 per call. |
| Youchuan V8.1 Remove Background API (Background Removal) | The background-removal endpoint takes any image and returns a single result with the subject isolated on transparency. That clean transparent output drops straight into product listings, marketing layouts, and compositing pipelines, priced at $0.086 per call. |
Inside the Youchuan V8.1 API: One Endpoint, Six Creative Engines
From four-up text-to-image renders and native 2K HD to multi-image blending, style transfer, and five-second animation, the Youchuan V8.1 API packages the family's signature aesthetic and fine-grained stylize, chaos, and weird controls behind one OpenAI-compatible endpoint with transparent pay-as-you-go pricing.
One Prompt, Four Signature Renders from the Youchuan V8.1 API
Every text prompt returns four distinct renders in a single call, each carrying the signature Youchuan aesthetic that competing models struggle to match. Prompts accept up to 1024 characters, so richly detailed scenes translate faithfully into saturated color and dramatic composition. This grid-of-four output gives art directors several strong directions to weigh before committing to a final frame.
Dial In Stylize, Chaos, and Weird
Push stylize from 0 to 1000 to control how strongly the house aesthetic takes hold, raise chaos up to 100 for wider variation, or crank weird as high as 3000 for genuinely unconventional results. Set quality to 1 or 4 to trade speed for finer detail, and fix the seed to reproduce any result exactly. Together these controls span safe brand-consistent output through bold experimental concept work.
Native 2K HD on the Youchuan V8.1 API
When crisp detail matters, enable the HD flag to render native 2K images with no upscaling artifacts, priced at 1.5x the base rate. Nine aspect ratios span square 1:1 through cinematic 21:9 and tall 9:21, covering social posts, print layouts, and widescreen key art. Because resolution is native rather than interpolated, fine textures and edges hold up under close inspection and large-format print.
Blend Up to Five Images into One
Blend mode fuses two to five source images into four cohesive results, with an optional prompt to steer the direction of the mix. Feed it product shots, mood references, and texture samples, and the model reconciles color, lighting, and subject into a single unified frame. Native 2K output is available here too. Concept teams reach for it to merge scattered references into one on-brand visual quickly.
Restyle Any Image While Keeping Its Composition
Describe a target style such as cyberpunk neon night, and style transfer repaints your input image into four variations while preserving the original composition. Structure and layout stay intact as color, texture, and mood shift to match the prompt. That makes it ideal for exploring alternate art directions on an approved layout, or adapting one hero image across several campaign themes.
Animate Any Still with the Youchuan V8.1 API
A single still image becomes four five-second clips, each rendered at 480p or 720p with motion set low or high. A short prompt describes the camera move or scene, turning a static hero shot into a gentle push-in or a lively animated moment. Whether teasing a product on social or previewing a shot for film, motion carries the same signature aesthetic from frame to sequence.
One Prompt, Three Renders: The Youchuan V8.1 API Against the Field
Feed a single identical prompt to the Youchuan V8.1 API and two rival image-to-video models, then watch the same scene animate three different ways so you can judge motion, coherence, and visual style side by side.
A bike courier on a fixed-gear threads through a rain-soaked Hong Kong night market, neon signs bleeding across the wet asphalt. He clips a fruit stall and oranges scatter and bounce everywhere as the vendor throws up his hands; the courier skids sideways, plants a foot, kicks off hard, and shoots a narrow gap between two passing trams while sparks trail off the rails behind him. Open on a low tracking shot chasing the rear wheel through the puddles, whip pan to catch the oranges tumbling mid-air, then cut to a drone that cranes up over the market roof as the bike bursts out the far end onto an empty road. Volumetric neon light, mirror reflections in every puddle, shallow depth of field, gritty cinematic realism. Ambient market chatter, tram bells, and a driving synth pulse that swells at the escape. 16:9 aspect ratio.

A young sky-sailor grips the rigging of a small wooden airship as it dives through a canyon of floating islands at golden hour. A flock of crystal-winged birds scatters ahead of the bow, then one bird darts back and snatches the brass compass straight out of her hand. She lunges along the boom, catches the bird by a tailfeather, and the two of them tumble off the deck together before her glider snaps open and she banks hard around a waterfall spilling into open sky. Begin with a sweeping orbit around the airship, cut to a first-person POV as she lunges down the boom, then drop to a low-angle upshot as the glider unfurls against the sun. Painted anime style with hand-drawn cel shading and lush watercolor skies. Whooshing wind, creaking timber, and a soaring orchestral swell at the moment the glider releases. 16:9 aspect ratio.

Youchuan V8.1 API: Common Developer Questions
The Youchuan V8.1 API gives developers programmatic access to Youchuan, the official Chinese lab of Midjourney, through Atlas Cloud. It covers a full creative suite spanning text-to-image, image-to-image, native image-to-video, image blending, style transfer, and background removal. Every mode sits behind one OpenAI-compatible endpoint, so you integrate the family's signature aesthetic without juggling separate accounts.
Six modes ship in the family. Text-to-image and image-to-image each return four variations from a prompt, blend fuses two to five source images into four composites, style transfer restyles a picture while preserving its composition, image-to-video animates a still into short clips, and background removal returns a clean transparent cutout.
Sign up on Atlas Cloud, generate one API key, and point your existing OpenAI-compatible client at the Youchuan V8.1 API endpoint. Pricing is pay-as-you-go with transparent per-call rates, so there is no subscription to commit to before your first request. Day-0 access means new modes are callable the moment the family ships. Start building today.
Image modes output native 2K HD up to 2048×2048 with no separate upscaling step, which avoids the artifacts that upscalers often introduce. On the motion side, image-to-video produces four five-second clips at either 480p or 720p, ready for social, ads, or pre-visualization.
Prompt-based modes expose the controls Midjourney users already know: aspect ratio, stylize, chaos, and weird, plus an optional style reference image. Together they let you dial in everything from tight commercial layouts to high-variance experimental looks inside a single call.
Most modes start at $0.086 per generation, including text-to-image, image-to-image, blend, background removal, and image-to-video. Style transfer runs at $0.129 for its four-result retexturing pass. Because billing is pay-as-you-go, you only pay for the calls you actually make.
Yes. Feed a still image to the image-to-video mode and it returns four five-second animations, letting you compare motion options before you commit to one. Pick 480p for fast drafts, or step up to 720p when you need cleaner output for client delivery.
Midjourney offers no official public API, so direct workflows usually depend on Discord automation or account-bound workarounds that are hard to scale. The Youchuan V8.1 API removes that friction by serving the same Midjourney-derived models over a standard REST endpoint on Atlas Cloud, backed by transparent pricing and production-grade uptime. For teams shipping products rather than experimenting in a chat client, that reliability is the deciding factor.
