1. Highest reasoning quality in the GPT-5 family

• Uses significantly more compute to "think harder" before responding.
• Designed for the toughest reasoning tasks where answer quality matters more than speed.
• Produces more precise, reliable, and detailed outputs than standard GPT-5.

2. Advanced multi-turn reasoning via Responses API

• Available only in the Responses API to support:
  • Multi-turn internal model interactions before returning a reply.
  • Advanced control patterns (e.g., background mode for long-running jobs).
• Ideal for complex workflows, deep planning, and multi-step analysis.

3. Configured for maximum effort by default

• Always runs with reasoning.effort: 'high' (no lower-effort mode).
• Prioritizes depth and correctness over latency and cost.

4. Multimodal input

• Accepts text + image as input.
• Outputs text, with strong instruction-following and analysis capabilities.

5. Tooling and ecosystem integration

• Supports Web Search, File Search, and Image Generation (as tools).
• Supports MCP and other Responses API tooling patterns.
• Does not support Code Interpreter and does not support Computer Use, keeping focus on pure reasoning + tools.

1. High-quality image generation

• Produces sharper, more detailed images than Gemini 2.0 Flash.
• Designed to generate professional-grade, aesthetically consistent visuals.

2. Advanced image editing capabilities

• Supports targeted, natural-language-driven edits (remove objects, change poses, recolor, blur backgrounds, etc.).
• Enables precise local transformations with simple prompts.

3. Multi-image fusion

• Can merge multiple input images intelligently into a single coherent scene.
• Useful for room restyling, product placement, and photorealistic composite images.

4. Character consistency across prompts

• Maintains the same character or object across multiple scenes and prompts.
• Suitable for brand assets, storytelling, product showcases, and multi-angle rendering.

5. Strong world knowledge

• Inherits Gemini's semantic understanding to reason about real-world objects.
• Can interpret hand-drawn diagrams and follow complex editing instructions.

6. Low latency + developer-friendly

• Based on the Gemini Flash family, optimized for responsiveness and cost-effectiveness.
• Easily testable and remixable using Google AI Studio's app builder.

7. Invisible SynthID watermarking

• All generated and edited images include Google's invisible SynthID watermark.
• Ensures traceability and responsible AI output.

8. Works with text + image input

• Accepts multiple images and text instructions simultaneously.
• Ideal for building interactive image tools, editors, and creative workflows.
