Keep the backpack straps and overall shape consistent with the original. Realistic transparent materials, botanical detail, premium scientific design, photorealistic integration. Preserve the woman’s exact identity, pose, clothing, rainforest, lighting, and camera composition.

Transform this image into a premium kitchen appliance commercial. Preserve the chef's face, chef jacket, posture, and kitchen composition. Upgrade the kitchen into a bright, modern luxury kitchen with elegant countertops, warm sunlight, polished appliances, clean reflections, fresh ingredients, and a professional lifestyle advertisement atmosphere. Keep it realistic, clean, warm, and trustworthy.

Change the season from autumn to deep winter: cover the pagoda roofs, trees and hills in fresh snow, turn the red maple leaves into bare snowy branches, make the lake partly frozen, and change the subtitle text to "Winter Journeys". Keep the title "KYOTO", the layout and the illustration style unchanged.

Place this earbuds case on a light oak bedside table next to a small potted plant and an open book, soft morning window light, shallow depth of field, realistic lifestyle photography. Keep the case, its shape, color and the "AURA" lettering exactly the same.

Redraw this photo as a hand-painted anime film still with soft cel shading, painterly watercolor backgrounds and warm golden-hour light. Keep the fisherman, his pose, the orange net and the harbor composition.

aspect_ratio empty when you want the output to follow the closest supported ratio from the first input image.2k when you need a higher-resolution result.Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/bytedance/seedream-v5.0-flash/edit with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Seedream v5.0 Flash Edit below.

time.sleep(2)Seedream v5.0 Flash Edit is a ByteDance model for image editing, exposed as a REST API on WaveSpeedAI. Seedream V5.0 Flash Edit by ByteDance edits and generates images from single-image or multi-reference inputs faster and at lower cost than Seedream V5.0 Pro Edit, supporting up to 10 reference images, aspect ratio selection, and 1K / 1.5K / 2K output at one price. 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 result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates Python, JavaScript, and cURL examples for submitting requests and polling results. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seedream-v5.0-flash-edit.
Seedream v5.0 Flash Edit starts at $0.0243 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`, `images`, `aspect_ratio`, `resolution`, `enable_base64_output`, `enable_sync_mode`. 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/bytedance/bytedance-seedream-v5.0-flash-edit.
Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.
Commercial usage rights depend on the model's license, set by its provider (ByteDance). Check the provider's applicable terms and WaveSpeedAI's Terms of Service before commercial use.
