Qwen

Total creative control: Qwen puts every dial and switch in your hands—from step count and guidance scale to seed and acceleration. Whether you're a power user fine-tuning every detail or a rapid prototyper seeking speed, Qwen adapts to your workflow.

Flexibility at scale: With support for extra-long prompts (up to 5000 characters) and multiple generation modes, Qwen handles everything from complex scene descriptions to targeted edits. The Z-Image mode offers a streamlined path for quick, aspect-aware generation.

Text to Image

Prompt: Up to 5000 characters, supporting rich descriptions and negative prompts.

Size options: Square (1024×1024), square_hd (1536×1536), portrait 3:4 (864×1152), portrait 9:16 (768×1344), landscape 4:3 (1152×864), landscape 16:9 (1344×768).

Inference steps: 2–250 (higher steps = more detail, slower generation).

Guidance scale: 0–20 (higher = stricter adherence to prompt).

Seed: Set for reproducibility or leave random.

Output format: PNG or JPEG.

Acceleration: None, regular, or high—trade speed for quality.

Safety checker: Optional filter for sensitive content.

Image to Image

Reference image: Required URL (JPEG, PNG, WebP).

Prompt: Up to 5000 characters.

Denoising strength: 0–1 (0 = minimal change, 1 = maximum deviation from original).

Full parameter set: Steps, guidance, seed, negative prompt, acceleration, output format, safety checker—same as text-to-image.

Image Edit

Prompt: Up to 2000 characters for describing the edit.

Image URL: Required input.

Image size: Adjustable (same options as text-to-image).

Steps: 2–49.

Num images: 1–4 outputs per request.

Sync mode: Enable for deterministic generation across multiple runs.

Guidance scale: Default 4, adjustable.

Negative prompt: Specify what to avoid.

Safety checker: Optional.

Z-Image

Prompt: Up to 1000 characters.

Aspect ratio: Required—1:1, 4:3, 3:4, 16:9, 9:16.

Simplified workflow: No advanced parameters; designed for speed and format compliance.

Concept exploration: Quickly generate multiple variations with long, detailed prompts.

Brand asset creation: Maintain consistency by setting seeds and using negative prompts to avoid unwanted elements.

Photo editing and retouching: Use Image-to-Image or Image Edit to change backgrounds, adjust lighting, or add/remove objects.

Content for social media: Generate assets in exact aspect ratios with Z-Image for platforms like Instagram, TikTok, or YouTube.

Batch experimentation: Run parallel generations with different seeds and guidance scales to find the perfect result.

Educational materials: Create diagrams, illustrations, and visual aids with precise control over style and content.

Text-to-image generation: 5–30 seconds depending on steps, acceleration, and resolution. High acceleration reduces time by up to 50%.

Image-to-image / edit: 10–35 seconds; denoising strength affects speed (higher strength may take slightly longer).

Z-Image: 3–15 seconds—optimized for rapid output.

Concurrency: Supports 100+ parallel requests; smart queue management.

Prompt limits: 5000 chars (text/image-to-image), 2000 chars (edit), 1000 chars (Z-Image).

Input formats: JPEG, PNG, WebP (max 10MB for image inputs).

Safety checker: Optional filter; adds minimal processing time.

Quick generate: Write prompt → choose size/parameters → generate → review → iterate with adjusted seed or guidance.

Edit iteration: Upload image → describe edit → adjust strength/steps → generate multiple versions → select best.

Batch production: Set seed and parameters → run multiple prompts in parallel → unify style with consistent negative prompts and guidance.

Team collaboration: Share generated assets, compare versions, and collect feedback in real time on FuseAITools.

Prompt engineering: Be specific—[Subject] + [Action/Scene] + [Style] + [Details]. Use negative prompts to exclude unwanted elements (e.g., "blurry, low quality, extra limbs").

Step/guidance tuning: Start with 20–30 steps and guidance 7–9; increase steps for fine detail, decrease for speed. For image-to-image, strength 0.3–0.7 often balances change and coherence.

Seed strategy: Use a fixed seed to reproduce results; vary seed for exploration. Save successful seeds for future batches.

Acceleration: Use "high" for drafts and internal reviews; "none" for final assets where quality is paramount.

Cost efficiency: Match resolution to need—use smaller sizes for thumbnails, larger for print. Batch similar requests to reuse parameters.

Safety checker: Enable only when necessary to avoid unintended filtering; disable for unrestricted creative exploration.

Granular control: Adjust steps, guidance, seed, and more—unmatched flexibility for power users.

Long prompt support: Up to 5000 characters for intricate descriptions and detailed edits.

Multiple modes: Text-to-image, image-to-image, edit, and Z-Image—all in one platform.

Speed options: Acceleration levels let you prioritize speed or quality on demand.

Reproducibility: Seed control ensures consistent outputs across sessions.

Best for: Designers, developers, content creators, researchers, and anyone needing precise, repeatable image generation.
