The Empirical Limits of Autoregressive Transformers
Modern multimodal transformers (GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro) are trained to maximize token likelihood. In media forensics, this produces a fatal vulnerability: models hallucinate plausibility when confronted with adversarial compression, acoustic vocoders, and physically impossible shadows. Below is the formal, reproducible benchmark proving why bicameral neurosymbolic logic is mathematically mandatory.
Empirical Benchmark Hardware Specification
All 2,850 adversarial benchmark evaluations and Z3 SMT refutation passes are executed across dedicated clusters of liquid-cooled compute accelerators within our sovereign research cleanroom. Every trial is recorded with microsecond timing precision and sealed under SHA-384 Merkle roots.
