Imagen4

Precision and flexibility: Imagen4 puts creative control at the forefront. Choose from standard, fast, or ultra modes to match your workflow. With optional negative prompts, adjustable aspect ratios, and seed parameters, you can fine-tune results to meet exact specifications.

Simplicity without compromise: Whether generating a single polished image or exploring dozens of variations, Imagen4 balances intuitive operation with professional-grade capabilities. Generous prompt limits and straightforward controls make it accessible for creators at every level.

Imagen4 Generate

Prompt required (up to 5000 characters) Optional negative prompt (up to 5000 characters) Aspect ratio: 1:1, 16:9, 9:16, 3:4, 4:3 Optional seed string (up to 500 characters) Ideal for general-purpose image creation: marketing assets, social media visuals, concept art, and drafts.

Imagen4 Fast

Prompt required (up to 5000 characters) Optional negative prompt (up to 5000 characters) Aspect ratio defaults to 16:9 Number of images: 1-4 per request Optional integer seed Ideal for high-speed exploration, A/B testing, and generating multiple variants in a single run.

Imagen4 Ultra

Prompt required (up to 5000 characters) Optional negative prompt (up to 5000 characters) Aspect ratio defaults to 1:1 Optional seed string (up to 500 characters) Ideal for premium-quality outputs: final assets, high-resolution visuals, and detail-sensitive projects.

Marketing assets: Generate consistent, on-brand visuals for campaigns, ads, and social content across multiple aspect ratios.

Concept iteration: Use Fast mode to explore dozens of variations quickly; refine with Generate or Ultra for final execution.

Polished final assets: Leverage Ultra mode for high-fidelity images suitable for print, hero visuals, or client presentations.

Creative exploration: Experiment with prompts and negative prompts to refine style, composition, and subject matter.

Batch ideation: Fast mode's multi-output capability supports rapid prototyping and team brainstorming sessions.

Generate mode: Balanced speed and quality; typical generation time varies based on prompt complexity and aspect ratio.

Fast mode: Optimized for speed; supports parallel generation of up to 4 images per request for rapid iteration.

Ultra mode: Prioritizes detail and fidelity; longer generation time suited for final assets.

Prompt length: Up to 5000 characters for both prompts and negative prompts, enabling highly detailed and nuanced instructions.

Aspect ratios: Supports 1:1, 16:9, 9:16, 3:4, 4:3 across all modes for flexible output formatting.

Seed control: Allows reproducibility and fine-grained variation tuning via optional seed parameters.

Quick create: Write a detailed prompt -> select mode (Generate, Fast, or Ultra) -> set aspect ratio and optional negative prompt -> generate -> review and refine.

Multi-output exploration: Use Fast mode with num_images set to 2-4 -> generate multiple variations simultaneously -> compare and select the best direction.

Reproducible generation: Set a seed value in Generate or Ultra mode to recreate consistent results across sessions or team workflows.

Team collaboration: Share generated assets and seed values to ensure alignment; iterate using negative prompts to eliminate unwanted elements.

Prompt crafting: Be specific and structured: [Subject] + [Action/Scene] + [Style/Composition] + [Key details]. For negative prompts, clearly list elements to avoid (e.g., "no text, no watermark, no blurry background").

Mode selection: Use Fast for early-stage ideation and volume generation. Use Generate for refined concepts. Use Ultra for final, high-stakes outputs where detail matters most.

Aspect ratio strategy: Match aspect ratio to intended use: 16:9 for widescreen visuals, 1:1 for social posts, 9:16 for vertical stories.

Seed utilization: When iterating, lock the seed to maintain composition consistency while tweaking prompts; change the seed to explore new compositions.

Quality control: Run initial explorations in Fast mode to validate prompt effectiveness; scale to Generate or Ultra once the creative direction is locked.

Three distinct modes: Tailor speed and quality to your workflow from rapid ideation to premium output.

Long prompt support: Up to 5000 characters for both prompts and negative prompts enables precise creative direction.

Negative prompting: Explicitly exclude unwanted elements for cleaner, more accurate results.

Flexible aspect ratios: Cover modern formats including square, widescreen, and vertical orientations.

Seed control: Ensure reproducibility and fine-tune variation across generations.

Multi-output capability: Fast mode supports 1-4 images per request for efficient exploration.

Best for: Designers, marketers, content creators, and teams requiring flexible, high-quality image generation with control over speed, fidelity, and output consistency.
