GPT Image 1.5 vs Gemini 1.0 Pro

1. State-of-the-Art Image Generation

• Produces high-quality, detailed images optimized for realism, style control and prompt fidelity.
• Designed to handle complex visual scenes, compositions and lighting conditions.

2. Natively Multimodal Architecture

• Understands and reasons over both text and images as inputs.
• Ideal for workflows like editing based on reference images, expanding sketches or mockups and visual concept development.

3. Flexible Output Resolutions & Quality Levels

• Supports multiple resolutions including 1024x1024, 1024x1536 and 1536x1024.
• Offers three quality tiers (Low, Medium, High) to balance cost, speed and maximum detail.

4. Multiple Pricing Models

• Pay-per-token for multimodal input: text tokens and image tokens.
• Pay-per-image generation for final output: low, medium and high quality tiers.
• Enables businesses to balance cost and output needs.

5. Broad Use Cases

• Product photography and marketing assets.
• Illustration, concept art and creative ideation.
• UX/UI mockups.
• Style-guided image creation.
• Generating reference images for design or storytelling.

6. Supported Across Major API Endpoints

• Available via Chat Completions, Responses, Realtime, Assistants and Images (generations/edits) endpoints.
• Allows tight integration into automated creative pipelines or user-facing apps.

7. Simplified Model Behavior for Stability

• No streaming, function calling, structured outputs or fine-tuning; focused solely on high-quality image generation.

8. Consistent Results via Snapshots

• Supports snapshots for version locking to ensure long-term reproducibility.

9. Ideal For

• Designers, marketers and creatives.
• Product teams needing image assets.
• App builders integrating image generation workflows.
• Agencies producing visual content at scale.

1. Strong all-purpose performance

• Designed as Google's balanced middle-tier model.
• Handles a wide range of tasks: reasoning, writing, coding, and problem-solving.

2. Natively multimodal understanding

• Trained from the ground up on text, images, audio, and video.
• More consistent multimodal reasoning than stitched-together architectures.

3. Great cost-to-capability ratio

• Offers much of Gemini Ultra's reasoning quality at a fraction of the cost.
• Strong default choice for large-scale production workloads.

4. Reliable reasoning and factual performance

• Performs well on benchmarks like MMLU, MMMU, and code reasoning.
• Handles long-form analysis, multi-step reasoning, and structured problem solving.

5. Advanced coding capabilities

• Supports major languages such as Python, Java, C++, Go.
• Generates, edits, debugs, and explains code with high accuracy.
• Powers advanced coding systems like AlphaCode 2.

6. Efficient and scalable

• Optimized for Google TPUs for lower latency and faster inference.
• Suitable for batch workloads, agents, and complex multi-step pipelines.

7. Strong multimodal reasoning

• Understands math, physics, and scientific diagrams.
• Handles mixed data inputs (charts + text, screenshots + instructions, etc.).

8. Enterprise-ready reliability

• Available through Google AI Studio and Vertex AI.
• Benefits from enterprise-grade governance, safety, privacy, and compliance.
