 The following list provides a glossary of key terms related to GitHub Copilot Chat:
 
 * **Content filtering**: A safety system that scans prompts and responses to detect and block harmful content before it is shown to the user.
-* **Hallucination**: A phenomenon where a language model generates output that sounds plausible but is factually incorrect, unsupported by the provided context, or entirely fabricated. Hallucinations are a known risk of large language models and are reason that human review of AI-generated output is important.

 * **Large language model (LLM)**: A type of neural network trained on a large body of text data that can generate, analyze, and transform natural language and code. GitHub Copilot Chat uses one or more LLMs to process prompts and produce responses.
 * **Prompt**: The input that is provided to GitHub Copilot Chat. The system combines the prompt with additional context (for example, open files or repository data) before sending it to the language model.
 * **Public code matching**: A feature that checks whether Copilot's suggestions match publicly available code. Depending on your settings, matching suggestions may be turned off or on; if turned on, it can either block or annotate with a reference to the source repository and any license information.

 GitHub Copilot Chat can be used in multiple scenarios across a variety of industries. Some examples of use cases include:
 
-* **Answering coding questions**: Ask GitHub Copilot Chat for help or clarification on specific coding problems and receive responses in natural language or code snippet format. The response may draw on the model's training data, repository context, and web search results (when enabled).
+* **Answering coding questions**: Ask GitHub Copilot Chat for help or clarification on specific coding problems and receive responses in natural language and/or as code snippets. The response may draw on the model's training data, repository context, and web search results (when enabled).
 * **Explaining code and suggesting improvements**: Generate natural language descriptions of a function's purpose, inputs, outputs, and dependencies. GitHub Copilot Chat can also suggest improvements such as better error handling or more readable control flow. Note that generated explanations may not always be accurate or complete and should be reviewed.
 * **Generating unit test cases**: GitHub Copilot Chat can help write unit test cases by generating code snippets based on the code open in the editor or a highlighted code snippet. It can suggest possible input parameters, expected output values, and assertions based on the function's signature and body. GitHub Copilot Chat can also suggest test cases for edge cases and boundary conditions—such as error handling, null values, or unexpected input types—that might be difficult to identify manually. Generated test cases may not cover all possible scenarios; manual testing and code review are still necessary.
 * **Proposing code fixes**: Get suggested fixes for bugs based on the error message, code syntax, and surrounding context. GitHub Copilot Chat can suggest changes to variables, control structures, or function calls that might resolve the issue. Note that suggested fixes may not always be optimal or complete.

 * **Limited scope**: GitHub Copilot Chat has been trained on a large body of code but may not be able to handle more complex code structures or obscure programming languages. For each language, the quality of suggestions depends on the volume and diversity of training data. For example, JavaScript is well-represented and well-supported, while less common languages may yield lower-quality results.
 * **Potential biases**: Training data drawn from existing code repositories may contain biases and errors that can be perpetuated by the tool. GitHub Copilot Chat may also be biased towards certain programming languages or coding styles, which can lead to suboptimal or incomplete code suggestions.
 * **Security risks**: Generated code can potentially expose sensitive information or vulnerabilities if not reviewed carefully. Always review and test generated code thoroughly, especially for security-sensitive applications.
-* **Matches with public code**: While the probability is low, GitHub Copilot Chat may produce code that matches code in the training set. You should take the same precautions as you would with any code that uses material you did not independently originate including rigorous testing, IP scanning, and checking for security vulnerabilities. For more information, see [AUTOTITLE](/copilot/how-tos/copilot-in-your-ide/copilot-for-common-tasks/find-matching-code).

 * **Inaccurate code**: GitHub Copilot Chat may generate code that appears valid but is not semantically or syntactically correct, or does not accurately reflect the intent of the developer. Carefully review and test generated code, particularly for critical or sensitive applications.
 * **Inaccurate responses to non-coding topics**: GitHub Copilot Chat is not designed to answer non-coding questions, and its responses in those contexts may be irrelevant or nonsensical.
 * **Risk of destructive commands (Windows Terminal)**: Copilot may suggest commands that could be destructive—such as deleting content or formatting a hard drive—that may be necessary in certain scenarios but can cause problems if used incorrectly. You are ultimately responsible for any commands you choose to execute. Despite the presence of fail-safes and safety mechanisms, executing commands carries inherent risks.
