The Model Spec specifies desired behavior for the models underlying OpenAI's products (including our APIs).
See the latest Model Spec rendered for human reading at model-spec.openai.com, read more about the Model Spec on the OpenAI Blog, or check out the latest Release Notes.
This repository contains the markdown source for the Model Spec, as well as an initial sample of evaluation prompts, and an archive of all released HTML versions of the Model Spec (starting from the second release on 2025年02月12日).
The prompts in examples/ are meant to test how the model behaves in challenging situations, and may be triggering or not safe for work;
including them is not intended as an endorsement of their content. Each file, e.g. examples/abcd.md, contains prompts meant to evaluate
a specific portion of the Model Spec, which is tagged with a corresponding markdown footnote (e.g. [^abcd]) in model_spec.md.
The Model Spec and evaluation prompts are dedicated to the public domain and marked with the Creative Commons CC0 1.0 deed.
