Features

Google Nano Banana Pro Text-to-Image Multi

Nano Banana Pro Text-to-Image Multi (Gemini 3.0 Pro Image) is Google’s next-generation text-to-image model with true multi-image generation. One prompt can return several high-quality images in a single run, perfect for rapid exploration, A/B testing, and storyboard creation. On WaveSpeedAI, this multi-image endpoint is offered at a flat $0.07 per image, with industry-leading cost efficiency.


🌟 Why it stands out

  • True multi-image generation Use the num_images style control in the UI to generate multiple images from one prompt in a single request, instead of looping over separate calls.

  • First-class multi-image support on WaveSpeedAI WaveSpeedAI is the first platform to expose Nano Banana Pro with genuine multi-image batching, combined with streamlined UI controls for aspect ratio, format, and sync mode.

  • Powerful prompt understanding Handles detailed, editorial-style prompts with nuanced control over subject, composition, lighting, and mood.

  • Aspect ratio and format flexibility Supports common ratios like 1:1, 3:2, 4:5, 16:9, and 9:16, plus multiple output formats, so images are ready for feeds, ads, banners, and mobile stories.

  • Fast and affordable at scale Batched generation plus a flat per-image price makes it ideal for campaigns, design sprints, and large creative pipelines.


⚙️ Capabilities

  • Input: one natural-language text prompt.
  • Output: multiple high-quality images from a single run.
  • num_images: controls how many images are generated per request.
  • aspect_ratio: choose from several presets (square, landscape, portrait, vertical, etc.).
  • output_format: jpeg, png, or webp for easy integration into design and product workflows.

Example use cases:

  • Generate several fashion shots from one art-direction prompt.
  • Produce multiple thumbnail variants for a single YouTube or e-commerce listing.
  • Create quick moodboard frames that share the same style but differ in composition.

💰 Pricing

  • Just $0.07 per image.

💡 Best Use Cases

  • A/B testing ad creatives Produce multiple variations of a campaign visual, then pick the best-performing one.

  • Thumbnail and banner exploration Quickly generate several layout and color options for social posts, storefronts, and landing pages.

  • Storyboards and keyframes Create multiple frames from a shared prompt to sketch out sequences for video, animation, or presentations.

  • Brand style development Lock in a consistent stylistic direction while exploring slight changes in pose, background, or framing.

  • Concept art and moodboards Batch-generate different interpretations of a scene to speed up early-stage visual ideation.


📝 Notes

  • Prompts must comply with Google’s safety policies. If a request fails or content is removed, review the prompt for restricted material and rephrase accordingly.
  • For consistent variations, keep the prompt and seed stable while adjusting only num_images.
  • Avoid conflicting instructions inside a single prompt (for example, “night” and “bright midday sun” together), as this can reduce quality or coherence.
  • Higher-level, descriptive prompts usually work better than extremely short or keyword-only inputs.
