HiDream I1 Dev — wavespeed-ai/hidream-i1-dev
HiDream I1 Dev is a fast, cost-efficient text-to-image model for generating high-quality images from prompts. It’s well-suited for concept art, marketing creatives, mascots, and prompt-driven typography-in-image needs (e.g., short words on signs or objects). You can specify exact output dimensions, set a seed for reproducibility, and choose the output format for easy downstream use.
Key capabilities
- Text-to-image generation from a single prompt
- Good for stylized characters, product concepts, and marketing visuals
- Supports prompt-specified text rendering inside the image (best for short phrases)
- Custom output size (set width/height directly)
- Seed control for reproducible generations
- URL output or BASE64 output (API only)
Use cases
- Mascot and character creation (e.g., branded animals, sticker-style art)
- Social creatives and ad variations from one prompt
- Concept exploration (composition, props, outfits, themes)
- Quick brand mockups (logos/words on props, posters, boards)
- Batch generation with consistent framing via fixed seed + size

Prompting guide
For images that include readable text, keep the on-image text short and unambiguous, and specify where it appears.
Template:
Subject + action + setting + style. Include the text “...” on [object] in [color/material], clearly readable.
Example prompts
- A cat wearing sunglasses holding a skateboard. The skateboard has the word “HiDream” written in red spray paint, clearly readable. Street photography style, high detail, strong contrast, 1024×1024.
- A clean product poster: a glossy sneaker on a studio background, with “HiDream” as small text on the shoe tag, minimalist design, soft shadows, crisp lighting.
