A surreal and dreamlike scene of a girl suspended just beneath the surface of still water, her white dress flowing around her like petals. Soft light filters from above, illuminating her serene expression. The composition feels ethereal, quiet, and almost mythical.
A tranquil wide-angle shot of a girl standing on a rocky cliff’s edge, facing a breathtaking vista of layered mountain ranges. Her loose hair moves in the wind, and the morning fog rolls gently over the peaks. The scene is vast, inspiring, and quietly powerful.
A light and airy street scene of a young woman browsing flowers outside a quaint corner shop. She wears a linen dress, straw bag slung casually over her shoulder, and sunlight casts soft glows through the flower petals. The ambiance is fresh, delicate, and full of life.
A dynamic urban street shot of a young man standing confidently in front of a colorful graffiti wall, hands in pockets. He wears a vintage jacket, loose jeans, and sneakers. The image is full of motion, texture, and raw street culture energy.
An epic fantasy illustration of a cloaked traveler standing on a levitating stone island high in the clouds. His silhouette faces a sky painted with soft violet and crimson hues, with distant floating temples barely visible. The tone is mysterious, majestic, and inspiring.

A wide-angle cinematic view of a woman standing at the edge of a rugged coastline, her dress rippling in the salty wind. Soft mist rises from crashing waves, and storm clouds roll in from the horizon. Her back is to the viewer, adding mystery and depth.
A painterly portrait of a young man seated by an arched window, the afternoon sun casting strong chiaroscuro across his face and collar. The background is dark and minimal, emphasizing classical composition and serene introspection.
A peaceful moment of a girl reading on a wooden bench overlooking misty green mountains. Her clothes are light and flowing, a gentle wind brushes through her hair, and distant birds fly across the valley. The composition conveys stillness, nature, and introspection.
A cinematic winter portrait of a young man standing under a streetlamp during heavy snowfall. His dark coat is dusted with snowflakes, and his breath is visible in the freezing air. The street is deserted, bathed in moody blue light, evoking quiet isolation.
A lone man walks past a towering modern building illuminated by colossal animated projections. The ground glows with digital patterns beneath his feet. The style is surreal and futuristic, evoking themes of surveillance and identity in a tech-dominated world.

Flux 1.1 Pro API — Quick start
Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/flux-1.1-pro with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Flux 1.1 Pro below.
HTTP example
# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/wavespeed-ai/flux-1.1-pro" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $WAVESPEED_API_KEY" \
-d '{
"prompt": "A cinematic shot of a city at sunset, soft golden light",
"aspect_ratio": "1:1",
"output_format": "jpg",
"seed": 0,
"enable_base64_output": false
}'
# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
-H "Authorization: Bearer $WAVESPEED_API_KEY"
# When status is "completed", read the output from data.outputs[0].Node.js example
// npm install wavespeed
const WaveSpeed = require('wavespeed');
const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env
const result = await client.run("wavespeed-ai/flux-1.1-pro", {

What is the Flux 1.1 Pro API?
Flux 1.1 Pro is a WaveSpeedAI model for image generation, exposed as a REST API on WaveSpeedAI. FLUX 1.1 Pro delivers professional photoreal image generation with enhanced realism and 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.
How do I call the Flux 1.1 Pro API?
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.
How much does Flux 1.1 Pro cost per run?
Flux 1.1 Pro starts at $0.040 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.
What inputs does Flux 1.1 Pro accept?
Key inputs: `prompt`, `aspect_ratio`, `seed`, `enable_base64_output`, `output_format`. 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.
How long does Flux 1.1 Pro take to generate?
Average end-to-end generation time on WaveSpeedAI is around 4 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.
Can I use Flux 1.1 Pro outputs commercially?
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.
