Gemini 3.1 Pro vs Nano Banana Pro

1. Google's most advanced reasoning Gemini model

• Designed to solve complex problems across multimodal inputs, including text, audio, images, video, PDFs, and full code repositories.
• Google highlights improved software engineering behavior, better agentic performance, and stronger usability in domains like finance and spreadsheets.

2. Large multimodal context with substantial output room

• Supports a 1,048,576 token input context window for large repositories, long documents, and multi-source workflows.
• Allows up to 65,536 output tokens for longer answers, plans, and code generations.

3. More efficient thinking with expanded controls

• Improves token efficiency and reasoning performance across use cases.
• Adds the MEDIUM thinking_level option to better balance cost, speed, and quality.

4. Strong support for production agents

• Supports grounding with Google Search, code execution, function calling, structured outputs, context caching, RAG, and chat completions.
• Also offers a custom-tools endpoint tuned for agentic workflows that mix bash-like tools with custom code tools.

1. Studio-quality image generation

• Built on Gemini 3 Pro for exceptionally high fidelity.
• Improved accuracy in composition, physics, lighting, and artistic style.

2. Precise creative controls

• Fine-tune lighting, camera, color grading, focus, and physical realism.
• Ideal for professional production workflows requiring creative direction.

3. Advanced text rendering & localization

• Produces crisp, accurate text inside images (signs, menus, labels, UI elements).
• Can localize text across different languages while preserving layout and style.

4. Multi-input creative workflows

• Supports up to 14 reference images for composite ads or mockups.
• Generates consistent resemblance for up to 5 individuals.
• Works with 2K and 4K resolution outputs.

5. Strong world knowledge

• Understands and reasons about real-world concepts.
• Generates factual assets like diagrams, maps, and educational content.

6. Google Search grounding (when enabled)

• Retrieves real-time web data to improve factual accuracy.
• Useful for data-driven graphics, infographics, and historically accurate visuals.

7. Enhanced editing capabilities

• Handles local edits, transformations, pose changes, and reference-based modifications.
• Maintains stylistic consistency during image-to-image operations.

8. Developer-friendly ecosystem

• Fully integrated into Google AI Studio, Vertex AI, and Antigravity platform.
• Supported in Adobe, Figma, and agentic development workflows.

9. SynthID provenance watermark

• Every generated or edited image includes an invisible SynthID watermark.
• Ensures content authenticity and responsible AI usage.
