PRs

Also written: PR

Requests to merge code changes into a project after review.

In plain terms

Pull requests are a way for developers to propose changes to a software project. When a developer finishes a new feature or fixes a bug, they create a pull request. This alerts other team members that the code is ready for review and potential inclusion in the main project.

Think of it like suggesting edits to a shared document. You make your changes in a separate copy, then ask the document owner to review your suggestions and merge them into the main version. This process helps ensure code quality and collaboration.

The expert version

Pull Requests (PRs) are a core feature of distributed version control systems like Git, facilitating collaborative software development. A developer creates a branch for their changes, commits them, and then opens a PR to propose merging those commits into a target branch (often the main development line). PRs trigger code reviews, automated checks, and discussions, serving as a central point for managing contributions and maintaining codebase integrity.

Why it matters now

Pull Requests are a core part of software development, the field where many frontier AI models are built and tested. Recent mentions highlight how AI tools are being used to generate code, automate tasks, and even assist in the review process for these code changes.

While you cannot directly create a pull request without a GitHub or similar account and a project, you can observe them. Visit the GitHub page for any popular open source AI project, like Hugging Face Transformers, and look for the 'Pull requests' tab. You can browse active and closed requests to see how developers propose and discuss code changes.
