Could you build this?
Partial Building an API wrapper or validation pipeline is easy, but formulating the actual mathematical structural verification metrics to detect hallucinations without retraining requires deep research in LLM latent representations.
What it would actually take: Implementing this requires a machine learning researcher familiar with transformer attention mechanisms and uncertainty estimation. The architecture involves capturing intermediate layer activations or token logit distributions across beam samples, computing structural graph tension or semantic consistency metrics, and exposing a low-latency Python/C++ inference hook (e.g., using vLLM or Hugging Face) before returning completions.
