Gemini 3 Pro Complete Guide: Images and Code Capabilities 2026

Gemini 3 Pro is Google's unified multimodal AI — one model that handles images, code, text, audio, and video. Here's how it works and how to get the most from it.

Key Concept: When you see "Gemini 3 Pro (images)" or "Gemini 3 Pro Preview (code)" in ChilledSites or the Google API, these refer to the same underlying model. Different names indicate optimised API endpoints or specific capability highlights — not different models.

What Is Gemini 3 Pro?

Gemini 3 Pro is Google's advanced multimodal AI model designed for reasoning, understanding, and generation across multiple types of content. Unlike traditional AI models that specialise in one type of task, Gemini 3 Pro is natively multimodal from the ground up.

Core Capabilities at a Glance

  • Single unified multimodal AI model from Google
  • Natively understands text, images, audio, video, and code
  • "Images" and "Code" are capabilities — not separate models
  • Different API endpoints optimise for specific use cases
  • 64K token context window for large, complex projects

The Unified Multimodal Architecture

The truth about "Gemini 3 Pro Images" vs "Gemini 3 Pro Code": these refer to the same model. Gemini 3 Pro is a single, unified multimodal model that handles multiple types of input and output simultaneously.

Unified Architecture

Gemini 3 Pro doesn't use separate components for different modalities. A single reasoning core processes all input types — text, images, code, audio, and video — together. This enables more sophisticated understanding and generation across all modalities than stitching together specialised models.

Cross-Modal Understanding

Because all capabilities share the same reasoning engine, Gemini 3 Pro can understand relationships between different types of content. It can analyse code and generate accompanying diagrams, or interpret text descriptions and create matching images — all within one integrated process.

Image Generation Capabilities

Key Image Generation Features

  • Pro-level quality: High-quality images with excellent detail and composition
  • Legible text: Unlike many image AI models, Gemini 3 Pro creates readable text within generated images
  • Context understanding: Interprets complex prompts accurately, including style, mood, and composition
  • Consistent style: Maintains visual consistency across multiple generated images
  • Multiple formats: Website graphics, marketing materials, social media, illustrations

Image Generation Use Cases

Website Graphics

Hero images, section backgrounds, illustrations, and custom graphics that perfectly match your website's design and brand identity.

Marketing Materials

Social media graphics, ad visuals, promotional images, and campaign assets with consistent branding and style.

Product Mockups

Visualise product concepts, create mockups, and generate lifestyle images without expensive photography.

Content Illustrations

Custom illustrations for blog posts, articles, presentations, and educational content that enhance your message.

Code and Website Building

Code Generation Capabilities

  • Complex reasoning: Handles sophisticated programming challenges and architectural decisions
  • Multi-language support: Proficient in JavaScript, Python, HTML, CSS, and many other languages
  • Code execution: Can execute code internally to verify correctness
  • Problem solving: Approaches coding challenges with systematic reasoning
  • 64K context window: Ample space for complex projects and large codebases

The Multimodal Advantage for Website Building

Because the same model generates both code and images, it can maintain consistency between your website's structure and its visual elements. The model understands how the images it creates will fit within the code it writes — all in one integrated reasoning process.

Practical Example: Building a restaurant website. Gemini 3 Pro writes the website code with proper structure and layout, generates custom food photography and ambiance images, and ensures the images match the code's design aesthetic — all from one integrated AI that understands the complete vision.

Gemini Model Hierarchy

Gemini 3 Pro (Latest)

Most advanced reasoning, multimodal capabilities including images and code, 64K context window. Best for complex projects requiring sophisticated understanding.

Gemini 2.5 Pro

Strong multimodal model, 64K context window, excellent for creative projects. Slightly less advanced than 3 Pro but still highly capable.

Gemini 2.5 Flash

Optimised for speed, 32K context window, cost-effective. Great for simpler tasks where quick responses matter more than maximum sophistication.

Gemini 1.5 Pro (Previous Generation)

32K context window. Still capable but superseded by newer versions in most use cases.

Best Practices for Using Gemini 3 Pro

For Image Generation

  • Be specific about style, colours, composition, and mood
  • Leverage legible text capability for graphics with words
  • Describe lighting, perspective, and atmosphere
  • Reference specific art styles for consistent aesthetic
  • Iterate and refine prompts based on initial outputs

For Code and Website Building

  • Provide detailed requirements and context
  • Leverage the 64K context window for large projects
  • Ask for architectural explanations
  • Use Gemini 3 Pro for problem-solving when stuck
  • Request code organisation strategies
