Prova vs Constitutional AI
Constitutional AI hopes a model trained the right way reasons correctly. Prova proves whether a specific reasoning chain is logically valid, independent of how the model was trained.
Try Prova freeConstitutional AI is a training methodology. It nudges a model toward a principle list at training time and relies on the model to self-critique at inference. Prova is a runtime verification system. It takes any AI reasoning chain, extracts the argument graph, and issues a signed certificate of structural validity. The two approaches solve different problems and are not mutually exclusive.
| Feature | Prova | Constitutional AI |
|---|---|---|
| Works on any model, not just self-critiquing ones | Yes | No |
| Formal per-instance verification | Yes | No |
| Detects circular reasoning | Yes | sometimes |
| Detects unsupported leaps | Yes | sometimes |
| Issues signed certificates | Yes | No |
| Immutable audit log | Yes | No |
| Requires retraining to change behavior | No | Yes |
| Runtime cost measured in seconds | Yes | No |
| Math foundation | H1(K;Z) = 0 | principle list + RLHF |
| Self-hosted deployment | Yes | model-dependent |
Where Prova is different
Works on any model you already use
Constitutional AI only helps if the model was trained with it. Prova verifies reasoning from any model, including closed-source APIs and open-weights checkpoints you did not train yourself.
Per-instance evidence, not population-level hope
Constitutional training improves aggregate behavior. It does not produce evidence that a specific reasoning chain on a specific Tuesday was logically sound. Prova does exactly that, per call.
Certificates are auditable artifacts
Regulators and model-risk reviewers want to see evidence for the decision in front of them. A principle list and a training recipe are not that evidence. A signed certificate is.
Use Constitutional AI to shape model behavior at training time. Use Prova to certify that a specific reasoning chain is logically valid at runtime. The two pair cleanly; they are not substitutes.
