Gemini 3 Pro — AI Detection Benchmark

What is Google Gemini Image Generation?

Google Gemini is Google's multimodal AI assistant that includes powerful image generation capabilities powered by Imagen technology. Available through the Gemini app, web interface, and API, it offers text-to-image generation integrated with Google's conversational AI.

What makes Gemini unique is its tight integration with Google's ecosystem and its implementation of SynthID, Google's advanced invisible watermarking technology for AI-generated content.

SynthID Watermarking

All images generated by Gemini include SynthID, Google's proprietary invisible watermarking:

How SynthID Works

• Embedded at the pixel level during generation
• Invisible to human perception
• Uses two neural networks (encoder/decoder)
• Survives common image transformations

SynthID Durability

SynthID is designed to survive:

• JPEG and WebP compression
• Cropping and resizing
• Color adjustments and filters
• Screenshots and re-uploads
• Format conversions

Detection Methods

• Google's official SynthID detector
• Third-party compatible tools
• Confidence-based scoring system
• Multi-level detection thresholds

Detecting Gemini Images

Gemini images are highly detectable due to SynthID:

Detection Rates

Condition	Detection Rate
Unmodified	95-99%
Light compression	90-95%
Heavy compression	80-90%
Cropped/resized	85-95%
Filtered/edited	75-90%
Screenshot	80-90%

Detection Tools

• Google's SynthID API
• Hive Moderation
• Our detection service
• Various research tools

Confidence Levels

SynthID reports detection in confidence levels:

• High confidence: Strong watermark detected
• Medium confidence: Watermark likely present
• Low confidence: Possible watermark
• Not detected: No watermark found

Removing SynthID from Gemini Images

SynthID is designed to be resilient, but removal is possible:

Removal Methods

1. Image Reconstruction

   • Use image-to-image with another AI model
   • ControlNet-based regeneration
   • Style transfer techniques

2. Spectral Processing

   • Analyze frequency domain
   • Target SynthID patterns
   • Preserve visual quality

3. Neural Filtering

   • AI-trained watermark removal
   • Pattern-aware processing
   • Quality preservation

Removal Effectiveness

Method	Success Rate	Quality Impact
Basic processing	20-40%	Low
Spectral analysis	50-70%	Low-Medium
Neural reconstruction	60-80%	Low
Combined methods	70-85%	Low-Medium

Challenges

• SynthID is pixel-level embedded
• Multiple redundant signatures
• Designed for resilience
• Quality/removal tradeoff
