Benchmark Methodology
GPT Image 1.5 images were tested across 7 AI detectors using a curated dataset of AI-generated and real photographs. The model uses 1 watermark type (DALL-E Watermark).
Each detector classifies images as AI-generated or real. We measure the detection rate — the percentage of GPT Image 1.5 images correctly identified as AI-generated. Higher rates mean the detector catches GPT Image 1.5 content more reliably.

GPT Image Generation refers to OpenAI's native image creation capability integrated directly into ChatGPT and GPT-4o. Unlike DALL-E which operates as a separate model, this represents OpenAI's evolution toward unified multimodal AI where text and image generation work seamlessly together.
The current implementation combines the conversational intelligence of GPT-4o with advanced image generation, allowing for iterative refinement and context-aware creation directly within chat conversations.
Key Features
Native Integration
- Built directly into ChatGPT interface
- No separate tool switching required
- Conversational image refinement
- Context-aware generation
Technical Capabilities
- Resolution: Up to 1792x1024 (landscape) or 1024x1792 (portrait)
- Quality: High-detail photorealistic and artistic outputs
- Speed: Fast generation (typically under 15 seconds)
- Accuracy: Excellent text rendering in images
Unique Advantages
- Iterative editing: "Make the sky bluer" type commands
- Context memory: References previous images in conversation
- Style consistency: Maintains style across multiple generations
- Text in images: Industry-leading text accuracy
C2PA Content Credentials
OpenAI implements C2PA (Coalition for Content Provenance and Authenticity) content credentials for all generated images:
What is C2PA?
- Industry standard for content authenticity
- Cryptographically signed metadata
- Includes generation information
- Machine and human verifiable
Implementation
ChatGPT-generated images include:
- Manifest: Signed by OpenAI
- Generator info: Model identification
- Timestamp: Creation time
- Claim generator: OpenAI attribution
Verification
- Check at contentcredentials.org
- Use C2PA verification tools
- Look for "cr" icon in supporting apps
- API-based verification available
Detecting ChatGPT Images
C2PA Detection
| Condition | Detection Rate |
|---|---|
| Original file | 99%+ |
| Re-saved (preserving metadata) | 95%+ |
| Screenshot | 0% (metadata lost) |
| Social media upload | Variable |
Statistical Detection
Even without C2PA metadata:
- AI pattern analysis: 70-85%
- Style recognition: 65-80%
- Artifact detection: 60-75%
Combined Approaches
- With C2PA: 95%+ detection
- Without C2PA: 65-85% detection
- Heavily processed: 50-70% detection
GPT Image Generation vs DALL-E 3
| Feature | GPT Image (ChatGPT) | DALL-E 3 API |
|---|---|---|
| Interface | Chat-integrated | API calls |
| Iterations | Conversational | New requests |
| Context | Full chat history | Per-request |
| Pricing | ChatGPT subscription | Per-image |
| Watermark | C2PA | C2PA |
| Resolution | 1792x1024 max | 1792x1024 max |
| Text accuracy | Excellent | Excellent |
Removing Detection Markers
C2PA Metadata Removal
C2PA metadata can be removed through:
- Screenshot capture - Creates new image without metadata
- Re-saving without metadata - Many editors strip C2PA
- Format conversion - Some formats don't preserve C2PA
- Social media upload - Many platforms strip metadata
Statistical Pattern Removal
- Image reconstruction - Process through another AI
- Spectral editing - Target frequency patterns
- Neural filtering - AI-based pattern removal
- Multi-step processing - Combine techniques
Effectiveness
| Method | C2PA Removal | Statistical Reduction |
|---|---|---|
| Screenshot | 100% | 0% |
| Metadata strip | 100% | 0% |
| Basic processing | 100% | 10-25% |
| Advanced processing | 100% | 40-60% |
| Neural reconstruction | 100% | 50-70% |
