Idle

Anime chibi-style illustration of a young girl with oversized, expressive eyes and a cheerful, playful expression. She has short, brightly colored hair with playful pigtails or messy spikes, and wears a cute, oversized outfit—perhaps a polka-dot dress or a hoodie with cartoon patterns—emphasizing the chibi aesthetic. Her pose is dynamic and whimsical, possibly mid-laugh or jumping, with limbs exaggeratedly proportioned. Background is minimal or stylized with soft pastel tones and floating bubbles or sparkles. Bright, saturated colors, clean lines, and exaggerated proportions typical of chibi anime art. Overall tone: joyful, innocent, and lighthearted. Shot: medium close-up, eye-level, focused on her face and upper body.

Image & Video Prompt Optimizer API

Overview

The WaveSpeedAI Prompt Optimizer enhances prompts specifically for image and video generation workflows. It restructures and enriches your input prompt to improve visual clarity, composition, cinematic framing, lighting, camera movement, and style consistency.

Designed for models such as Nano Banana, Seedream, FLUX, Wan, Kling, Veo, Seedance, Hailuo, and other leading visual-generation systems.

Key Features

  • Improves visual composition (lighting, framing, perspective)
  • Expands prompts with cinematic and artistic attributes
  • Enhances style, mood, and motion for video models
  • Reduces ambiguity and ensures consistent reproducible outputs
  • Works seamlessly in automated pipelines and API workflows

Why Use It?

Raw user prompts often produce unstable or low-quality visual outputs. The Prompt Optimizer standardizes and enriches prompts, leading to:

  • Better image detail and fidelity
  • More stable, coherent video motion
  • Consistent art direction across batches
  • Improved adherence to user intent

Usage

Send any raw text prompt to the /v1/prompt/optimize endpoint and receive a fully optimized version ready for visual generation models.
