VendorBench-100: A Unified Cross-Paradigm Benchmark for Deepfake Image Detection

arXiv:2607.06254v1 Announce Type: cross Abstract: Deepfake image detection is currently served by three fundamentally different paradigms: commercial APIs, zero-shot vision-language models (LLMs), and open-source detectors. Despite their widespread use, these paradigms are rarely evaluated under a common protocol, making direct comparison difficult. We introduce VendorBench-100, a cross-paradigm benchmark that evaluates 36 representative models using a single adversarial 100-image corpus, a unified output schema, and a common evaluation framework. To ensure reliable assessment under the corpus

Why this matters
Why now

The proliferation of deepfake technology across various modalities necessitates robust and comparable detection methods to maintain digital trust and security.

Why it’s important

A unified benchmark standardizes the evaluation of deepfake detection systems, enhancing their reliability and enabling better-informed deployment decisions across industries and governments.

What changes

The ability to objectively compare and select deepfake detection solutions, irrespective of their underlying paradigm, significantly improves.

Winners
  • · Security software vendors
  • · Social media platforms
  • · Government agencies investigating digital fraud
  • · Organizations relying on digital identity verification
Losers
  • · Deepfake creators
  • · Providers of unproven or ineffective detection solutions
  • · Bad actors exploiting synthetic media
Second-order effects
Direct

Improved deepfake detection capabilities lead to higher confidence in digital content authenticity.

Second

Enhanced detection may spur further innovation in adversarial deepfake generation techniques, creating an arms race.

Third

The benchmark could become a de facto standard, influencing research directions and market consolidation for deepfake countermeasures.
