FAQ
What is verifier engineering?
Verifier engineering is a post-training paradigm for foundation models that uses a suite of automated verifiers to perform verification tasks and provide feedback to the model, structured in three stages: search, verify, and feedback.
What are the three stages of verifier engineering?
The three stages are search, verify, and feedback. Search involves identifying relevant verification tasks, verify performs automated checking, and feedback delivers the results to the foundation model.
How does verifier engineering differ from traditional training?
Verifier engineering focuses on post-training supervision through automated verifiers rather than relying solely on human-generated labels, aiming to provide scalable and effective feedback for foundation models.
