A grand steampunk airship soaring through the sky, with intricate brass and copper details, large propellers spinning, and a massive balloon filled with hot air. The airship is adorned with Victorian-style architecture, featuring ornate railings and decorative elements. The sky is a brilliant blue with fluffy white clouds, and the airship casts a shadow on the landscape below. The scene conveys a sense of adventure and exploration

A teenage boy wanders through a misty enchanted forest, wearing a soft cloak and leather boots. Light glimmers through the leaves as tiny glowing motes float around him. The atmosphere is magical, like a scene from a fantasy novel.

A soft-lit portrait of a young man with tousled black hair, seated casually in a neutral-toned room. He wears a stone gray sweatshirt, light falls naturally across his face, casting gentle shadows. The background is minimal, evoking a calm, introspective mood.

A minimalist fashion portrait of a woman in a sleek black turtleneck, seated on a modern white chair in an all-white room. Her gaze drifts off-camera, creating a cool, detached elegance. The composition is clean, with strong contrast and subtle shadow work.

A cozy digital illustration of a girl sitting by a frosted window, wrapped in a chunky knitted sweater, holding a steaming mug. Snow falls softly outside, while warm light glows indoors. Her relaxed posture evokes a feeling of quiet winter comfort.

A vintage-style photograph of a young woman in a crisp white blouse gently adjusting her hair before a tall mirror. The room is softly lit by window light, and subtle dust particles float in the air. The mirror reflects a faded warmth, like a memory from the past.

A cinematic silhouette of a woman standing still at the edge of the sea, framed by the golden-orange glow of a low-setting sun. Her hair is gently lifted by the breeze, and her figure is outlined crisply against the shimmering waves. The mood is reflective and timeless.

An enchanting illustration of a young girl wrapped in a fluffy white parka standing still in a quiet snowy forest, while a red fox looks up at her curiously. Snowflakes gently fall, and the color palette is soft and desaturated, evoking a calm winter fairytale moment.

A serene image of a young woman hiking along a winding mountain trail, surrounded by towering pine trees. She wears earth-tone hiking gear and a canvas backpack, her steps light and steady. The scene is sun-dappled, crisp, and meditative, evoking nature’s quiet strength.

A warm retro-style morning scene: a woman in a faded floral robe stands quietly by a sunlit kitchen window, sipping tea from a porcelain cup. The old tiles, wooden shelves, and blooming potted plants evoke a nostalgic, peaceful home atmosphere from the 1980s.

A fantasy-styled illustration of a child standing in an open field under a vast star-filled sky. They raise their hands toward the constellations, as faint magical trails connect stars into glowing shapes. The atmosphere is peaceful, otherworldly, and full of wonder.

A delicate anime-style illustration of a high school girl walking alone down a sleepy suburban street at dusk, her schoolbag in hand. The sky is tinted orange-pink, and cicadas hum in the background. Power lines stretch overhead, capturing a familiar and gentle evening calm.

A grainy retro-inspired image of a young woman walking briskly along an underground subway platform, her denim jacket slightly oversized and skirt swaying with each step. Fluorescent lights flicker overhead, and the mood feels like a lost scene from a 90s urban diary.

FLUX 1.1 Pro Ultra is the latest FLUX model delivering professional-grade photoreal image generation with support up to 2K resolution. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/flux-1.1-pro-ultra.
Flux 1.1 Pro Ultra starts at $0.060 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `prompt`, `aspect_ratio`, `seed`, `enable_base64_output`, `output_format`, `raw`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/wavespeed-ai/flux-1.1-pro-ultra.
Average end-to-end generation time on WaveSpeedAI is around 9 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.
Commercial usage rights depend on the model's license, set by its provider (WaveSpeedAI). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
