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. 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.
