Building TruthLens AI: Explainable Image Analysis with Gemma 4

Description and use

TruthLens AI is an image analysis tool that uses Gemma 4 to explain the probability of an image being fake or real.

Problem

AI-generated and manipulated images are increasingly hard to detect by visual inspection alone.

Outcome

TruthLens provides a probabilistic, explainable assessment of image authenticity, combining detection evidence with Gemma 4 reasoning to produce confidence scores and human-readable explanations.

Workflow

• Upload image
• AI image detection model analyzes image and outputs evidence signals
• Gemma 4 interprets evidence and generates explanations
• Present probabilistic result with confidence and explanation

Evidence

AI-generated and manipulated images are becoming increasingly difficult to identify. A simple visual inspection is often not enough to determine whether an image has been altered.

Source

TruthLens combines AI-based image detection and Gemma 4 reasoning to investigate suspicious images.

Source

The detection model provides evidence. Gemma 4 provides reasoning.

Source

TruthLens provides probabilistic analysis. Its results should not be treated as definitive proof that an image is authentic, manipulated, or AI-generated.
