Outcome-Based Reward Models
Reward models can be designed to evaluate entire input-output sequences, a method that is highly effective for tasks where correctness can be verified by simply checking the final result. This approach focuses on the outcome rather than the process used to achieve it.

Limitations of Human Feedback for LLM Alignment
An AI development team aims to align a large language model to be more helpful. They create a dataset where, for a given prompt, they collect two different responses from the model and have human annotators label which of the two responses is superior. What is the primary and most direct function of this specific type of dataset in a human preference alignment methodology?
A development team is refining a large language model to be more helpful and harmless. They are using a method that involves learning from human judgments about which of two responses is better. Arrange the following three core stages of this alignment process into the correct chronological order.

Insufficiency of Outcome-Based Rewards for Complex Reasoning
A company is training a language model to act as an automated assistant for processing loan applications. The model must follow a specific, legally-mandated, multi-step procedure to ensure fairness and compliance (e.g., checking credit history, verifying income, providing specific disclosures). The company decides to train the model using a system that provides a large positive reward only if the final loan decision (approve/deny) is correct based on the applicant's overall profile. What is the most significant weakness of this training strategy?
