Try it now

Try the GPT-4 powered PR-Agent instantly on your public GitHub repository. Just mention @CodiumAI-Agent and add the desired command in any PR comment. The agent will generate a response based on your command. For example, add a comment to any pull request with the following text:

@CodiumAI-Agent /review

and the agent will respond with a review of your PR

Review generation process

To set up your own PR-Agent, see the Installation section below. Note that when you set your own PR-Agent or use CodiumAI hosted PR-Agent, there is no need to mention @CodiumAI-Agent .... Instead, directly start with the command, e.g., /ask ....


Installation

To use your own version of PR-Agent, you first need to acquire two tokens:

  1. An OpenAI key from here, with access to GPT-4.
  2. A GitHub personal access token (classic) with the repo scope.

There are several ways to use PR-Agent:

Locally

GitHub specific methods

GitLab specific methods

BitBucket specific methods

  2. Improved privacy - No data will be stored or used to train models. PR-Agent Pro will employ zero data retention, and will use an OpenAI account with zero data retention.
  3. Improved support - PR-Agent Pro users will receive priority support, and will be able to request new features and capabilities.
  4. Extra features -In addition to the benefits listed above, PR-Agent Pro will emphasize more customization, and the usage of static code analysis, in addition to LLM logic, to improve results. See here for a list of features available in PR-Agent Pro.

Why use PR-Agent?

A reasonable question that can be asked is: "Why use PR-Agent? What makes it stand out from existing tools?"

Here are some advantages of PR-Agent:

  • We emphasize real-life practical usage. Each tool (review, improve, ask, ...) has a single GPT-4 call, no more. We feel that this is critical for realistic team usage - obtaining an answer quickly (~30 seconds) and affordably.
  • Our PR Compression strategy is a core ability that enables to effectively tackle both short and long PRs.
  • Our JSON prompting strategy enables to have modular, customizable tools. For example, the '/review' tool categories can be controlled via the configuration file. Adding additional categories is easy and accessible.
  • We support multiple git providers (GitHub, Gitlab, Bitbucket), multiple ways to use the tool (CLI, GitHub Action, GitHub App, Docker, ...), and multiple models (GPT-4, GPT-3.5, Anthropic, Cohere, Llama2).

Data privacy

If you host PR-Agent with your OpenAI API key, it is between you and OpenAI. You can read their API data privacy policy here: https://openai.com/enterprise-privacy

When using PR-Agent Pro 💎, hosted by CodiumAI, we will not store any of your data, nor will we use it for training. You will also benefit from an OpenAI account with zero data retention.
