Запрос вопросов GitHub Copilot в GitHub

Overview

GitHub Copilot Chat in GitHub is a chat interface that lets you ask and receive answers to coding-related questions on the GitHub website.

Copilot Chat can help you with a variety of coding-related tasks, like offering you code suggestions, providing natural language descriptions of a piece of code's functionality and purpose, generating unit tests for your code, and proposing fixes for bugs in your code. For more information, see Responsible use of GitHub Copilot Chat in GitHub.

On GitHub, you can use Copilot Chat to ask:

• General software-related questions, without a particular context. For more information, see Asking a general question about software development.
• Exploratory questions asked in the context of a specific repository. For more information, see Asking exploratory questions about a repository.
• Questions asked in the context of a specific repository, file or symbol. For more information, see Asking a question about a specific file or symbol.
• Questions about a specific file or specified lines of code within a file. For more information, see Asking questions about specific pieces of code.
• Questions about a pull request diff. For more information, see Finding out about the changes in a pull request.
• Questions about a specific issue. For more information, see Asking a question about a specific issue or discussion.

Limitations

• The quality of the results from Copilot Chat may, in some situations, be degraded if very large files, or a large number of files, are used as a context for a question.

Powered by skills

When using the GPT-4o and Claude 3.5 Sonnet models, Copilot has access to a collection of skills to fetch data from GitHub, which are dynamically selected based on the question you ask. You can tell which skill Copilot used by clicking to expand the status information in the chat window.

You can explicitly ask GitHub Copilot Chat in GitHub to use a particular skill - for example, Use the Bing skill to find the latest GPT4 model from OpenAI.

AI models for Copilot Chat

The following models are currently available through multi-model Copilot Chat:

• GPT 4o: This is the default Copilot Chat model. It is a versatile, multimodal model that excels in both text and image processing and is designed to provide fast, reliable responses. It also has superior performance in non-English languages. Learn more about the model's capabilities and review the model card. Gpt-4o is hosted on Azure.
• Claude 3.5 Sonnet: This model excels at coding tasks across the entire software development lifecycle, from initial design to bug fixes, maintenance to optimizations. Learn more about the model's capabilities or read the model card. GitHub Copilot uses Claude 3.5 Sonnet hosted on Amazon Web Services.
• o1: This model is focused on advanced reasoning and solving complex problems, in particular in math and science. It responds more slowly than the gpt-4o model. You can make 10 requests to this model per day. Learn more about the model's capabilities and review the model card. o1 is hosted on Azure.
• o1-mini: This is the faster version of the o1 model, balancing the use of complex reasoning with the need for faster responses. It is best suited for code generation and small context operations. You can make 50 requests to this model per day. Learn more about the model's capabilities and review the model card. o1-mini is hosted on Azure.

For more information about the o1 models, see Models in the OpenAI Platform documentation.

For more information about the Claude 3.5 Sonnet model from Anthropic, see "Using Claude 3.5 Sonnet in GitHub Copilot."

Limitations of AI models for Copilot Chat

• If you want to use the skills listed in the table above, on the GitHub website, only the GPT 4o and Claude 3.5 Sonnet models are supported.
• Experimental pre-release versions of the models may not interact with all filters correctly, including the duplication detection filter.

Changing your AI model

1. If you access Copilot Chat through a Copilot Business subscription, your organization must grant members the ability to switch to a different model. See "Managing policies for Copilot in your organization."
