How GPT-5.5 and GPT Image 1 differ
What the numbers mean in practice when choosing between GPT-5.5 and GPT Image 1.
-
Both models cost the same on input: $5 per million tokens.
-
These are different kinds of model: GPT-5.5 is a text model while GPT Image 1 is an image model, so they often complement each other in a workflow rather than compete.
Strengths side by side
Where each model shines, according to benchmarks and provider positioning.
GPT-5.5
1. Strongest Agentic Coding Model
- State-of-the-art on Terminal-Bench 2.0 (82.7%), Expert-SWE (73.1%), and SWE-Bench Pro (58.6%), outperforming GPT-5.4 on complex coding tasks.
- Holds context across large systems, reasons through ambiguous failures, and carries changes through surrounding codebases with fewer tokens.
2. Higher Intelligence at GPT-5.4 Latency
- Co-designed, trained, and served on NVIDIA GB200/GB300 NVL72 systems to match GPT-5.4 per-token latency while performing at a significantly higher level.
- Uses fewer tokens to complete the same tasks, making it more efficient as well as more capable.
3. Powerful for Knowledge Work & Computer Use
- Scores 84.9% on GDPval (44 occupations) and 78.7% on OSWorld-Verified for autonomous computer operation.
- Excels at generating documents, spreadsheets, and reports; naturally moves across finding information, using tools, and checking output.
4. Scientific Research Co-Scientist
- Leading performance on GeneBench, BixBench, and FrontierMath; helped discover a new proof about Ramsey numbers verified in Lean.
- Strong enough to meaningfully accelerate progress at the frontiers of biomedical and mathematical research.
GPT Image 1
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
- Can understand and reason over both text and images as inputs.
- Ideal for workflows like:
- Editing based on reference images
- Expanding sketches or mockups
- Visual concept development
3. Flexible Output Resolutions & Quality Levels
- Supports multiple resolutions, including:
- 1024x1024
- 1024x1536
- 1536x1024
- Offers three quality tiers (Low, Medium, High) to optimize for:
- Cost efficiency
- Speed
- Maximum detail
4. Multiple Pricing Models
- Pay-per-token for multimodal input:
- Text input tokens
- Image input 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
- Images (generations, edits)
- 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 without extra logic layers.
8. Consistent Results via Snapshots
- Supports snapshots for version locking.
- Ensures long-term reproducibility across production pipelines.
9. Ideal For
- Designers, marketers, and creatives
- Product teams needing image assets
- App builders integrating image generation workflows
- Agencies producing visual content at scale
