OpenAI Model Spec

Q: How deeply does Reinforcement Learning from Human Feedback cover OpenAI Model Spec?

Explains purpose, stakeholders, and alignment context but stops short of specifying the document’s complete policy contents or training algorithm.

As explained in Reinforcement Learning from Human Feedback

A model specification is a written behavioral specification defining intended behaviors and principles for a language model.

The OpenAI Model Spec is a written behavioral specification that states intended model behaviors before fine-tuning and helps steer models through the API and future training. It turns otherwise implicit post-training goals into an explicit reference for comparing designed behavior with observed behavior. section 17.2

A model specification supports several parts of the release process:

Clarifies which behaviors designers want or reject, making prioritization and data decisions easier. section 17.2
Gives developers a clearer basis for judging whether encountered behavior is intentional. section 17.2
Makes post-training goals more transparent and auditable to the public and other stakeholders. section 17.4

Model specification and constitutional alignment

OpenAI released a Model Spec in 2024 as a statement of intended model behavior. Its policy-referencing direction is compared with Constitutional AI, while deliberative alignment trains reasoning models such as o1 while they reference safety or behavior policies. section 12.5.1

Unlike a list of intermediate training instructions, a model specification describes the intended outcome of the alignment process. It therefore provides a shared behavioral target across model development, product deployment, and public communication. section 17.2 section 17.4
