Repligraphs: A Primitive for AI Provenance
A repligraph is a new primitive that allows for the provable verification of AI-generated artifacts by leveraging the deterministic nature of large language models. Unlike human-created content, which cannot be cryptographically proven to originate from a specific individual, AI outputs can be re-executed to confirm their provenance. This technology has potential applications in various fields, including software development, contract disputes, and establishing model personhood.
- ▪Humans cannot produce repligraphs because there is no way to definitively prove that a specific person wrote a particular text.
- ▪An LLM is a deterministic function, meaning anyone can re-execute it with the same input to verify that it produces the same output.
- ▪This attestation primitive can be used to prove that an artifact is AI-generated, distinguishing it from human-authored content.
- ▪The concept has potential applications in software development, contract disputes, game theory, and superforecasting.
- ▪Users can record and verify their first repligraph by using an AI agent to build something based on a specific prompt.

Opening excerpt (first ~120 words) tap to expand
A repligraph is an artifact that was provably produced by a specific mind. Humans are not capable of producing repligraphs: There is no way for me to prove that I wrote this text. Sure, it’s hosted on my website, but that proves nothing about its provenance. Nor would a cryptographic signature help: Maybe I hired a ghostwriter. Maybe someone hacked me. There is a way, however, to prove that an artifact is AI-generated. An LLM is just a function. If that function is executed deterministically, then anyone can re-execute it with the same input and verify that it produces the same output. This is a new attestation primitive with myriad applications in software development, contract disputes, game theory, superforecasting, model personhood, and more.
