# AI/ML powered features

GitLab is creating AI-assisted features across our DevSecOps platform. These features aim to help increase velocity and solve key pain points across the software development lifecycle.

## Enable AI/ML features

> Introduced in GitLab 16.0 and [actively being rolled out](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/118222).

Prerequisites:

- You must have the Owner role for the group.

To enable AI/ML features for a top-level group:

- Enable [Experiment features](group/manage.md#enable-experiment-features).
- Enable [third-party AI features](group/manage.md#enable-third-party-ai-features) (enabled by default).
  To disable AI features powered by third-party APIs, clear this setting.

These settings work together so you can have a mix of both experimental and third-party AI features.

## Generally Available AI features

When a feature is [Generally Available](../policy/experiment-beta-support.md#generally-available-ga),
it does not require [Experiment features to be enabled](group/manage.md#enable-experiment-features).
Some of these features might require [third-party AI features to be enabled](group/manage.md#enable-third-party-ai-features).

The following feature is Generally Available:

- [Suggested Reviewers](project/merge_requests/reviews/index.md#suggested-reviewers)

## Beta AI features

[Beta features](../policy/experiment-beta-support.md#beta) do not require
[Experiment features to be enabled](group/manage.md#enable-experiment-features).

The following feature is in Beta:

- [Code Suggestions](project/repository/code_suggestions.md)

## Experiment AI features

[Experiment](../policy/experiment-beta-support.md#experiment) AI features require
[Experiment features to be enabled](group/manage.md#enable-experiment-features) as well as [third-party AI services to be enabled](group/manage.md#enable-third-party-ai-features).

### Explain Selected Code in the Web UI **(ULTIMATE SAAS)**

> Introduced in GitLab 15.11 as an [Experiment](../policy/experiment-beta-support.md#experiment) on GitLab.com.

This AI feature is an [Experiment](../policy/experiment-beta-support.md) on GitLab.com that is powered by Google's Codey for Code Chat (codechat-bison).

GitLab can help you get up to speed faster if you:

- Spend a lot of time trying to understand pieces of code that others have created, or
- Struggle to understand code written in a language that you are not familiar with.

By using a large language model, GitLab can explain the code in natural language.

Prerequisites:

Additional prerequisites [beyond the two above](#experiment-ai-features).

- The project must be on GitLab.com.
- You must have the GitLab Ultimate subscription tier.
- You must be a member of the project with sufficient permissions to view the repository.

To explain your code:

1. On the left sidebar, at the top, select **Search GitLab** (**{search}**) to find your project.
1. Select any file in your project that contains code.
1. On the file, select the lines that you want to have explained.
1. On the left side, select the question mark (**{question}**). You might have to scroll to the first line of your selection to view it. This sends the selected code, together with a prompt, to provide an explanation to the large language model.
1. A drawer is displayed on the right side of the page. Wait a moment for the explanation to be generated.
1. Provide feedback about how satisfied you are with the explanation, so we can improve the results.

You can also have code explained in the context of a merge request. To explain
code in a merge request:

1. On the left sidebar, at the top, select **Search GitLab** (**{search}**) to find your project.
1. On the left sidebar, select **Code > Merge requests**, then select your merge request.
1. On the secondary menu, select **Changes**.
1. On the file you would like explained, select the three dots (**{ellipsis_v}**) and select **View File @ $SHA**.

   A separate browser tab opens and shows the full file with the latest changes.

1. On the new tab, select the lines that you want to have explained.
1. On the left side, select the question mark (**{question}**). You might have to scroll to the first line of your selection to view it. This sends the selected code, together with a prompt, to provide an explanation to the large language model.
1. A drawer is displayed on the right side of the page. Wait a moment for the explanation to be generated.
1. Provide feedback about how satisfied you are with the explanation, so we can improve the results.

## Data Usage

GitLab AI features leverage generative AI to help increase velocity and aim to help make you more productive. Each feature operates independently of other features and is not required for other features to function.

### Progressive enhancement

These features are designed as a progressive enhancement to existing GitLab features across our DevSecOps platform. They are designed to fail gracefully and should not prevent the core functionality of the underlying feature. Please note each feature is subject to its expected functionality as defined by the relevant [feature support policy](../policy/experiment-beta-support.md).

### Stability and performance

These features are in a variety of [feature support levels](../policy/experiment-beta-support.md#beta). Due to the nature of these features, there may be high demand for usage which may cause degraded performance or unexpected downtime of the feature. We have built these features to gracefully degrade and have controls in place to allow us to mitigate abuse or misuse. GitLab may disable **beta and experimental** features for any or all customers at any time at our discretion.

## Third party services

### Data privacy

Some AI features require the use of third-party AI services models and APIs from: Google AI and OpenAI. The processing of any personal data is in accordance with our [Privacy Statement](https://about.gitlab.com/privacy/). You may also visit the [Sub-Processors page](https://about.gitlab.com/privacy/subprocessors/#third-party-sub-processors) to see the list of our Sub-Processors that we use in order to provide these features.

Group owners can control which top-level groups have access to third-party AI features by using the [group level third-party AI features setting](group/manage.md#enable-third-party-ai-features).

### Model accuracy and quality

Generative AI may produce unexpected results that may be:

- Low-quality
- Incoherent
- Incomplete
- Produce failed pipelines
- Insecure code
- Offensive or insensitive

GitLab is actively iterating on all our AI-assisted capabilities to improve the quality of the generated content. We will continue improving the quality through prompt engineering, evaluating new AI/ML models to power these features, and through novel heuristics built into these features directly.
