| **Model Provider**         | The company or project offering API access to a language model. Examples: **OpenAI**, **Azure OpenAI Service**, **Anthropic**, **Google (Gemini)**, **Mistral**, **Meta (LLaMA)**, **Cohere**, **Aleph Alpha**, **xAI (Grok)**, **AWS Bedrock (multi-provider)**. |
| **Model**                  | The specific language model you interact with. Examples: `gpt-4-turbo`, `claude-3-opus`, `gemini-pro`.                                                                                                                                                            |
| **System Prompt**          | A special instruction that sets the model’s behavior, role, or context before processing user prompts.                                                                                                                                                            |
| **Prompt**                 | The input message or instruction sent by the user to the model.                                                                                                                                                                                                   |
| **Completion / Response**  | The model's generated reply to the user prompt.                                                                                                                                                                                                                   |
| **Token**                  | The smallest unit of text processed for billing and context limits. Includes input and output tokens.                                                                                                                                                             |
| **Context Window**         | The maximum number of tokens the model can handle in a single request, combining prompt and response.                                                                                                                                                             |

## ✅ Tool-Calling and Automation Terms

| Term                          | Description                                                                                                                                                                                |

| **Tool Call / Function Call** | A structured API call generated by the model to invoke external functionality (e.g., weather lookup, database query).                                                                      |

| **Tool Use Auto Loop**        | An automatic process where the model issues one or more tool calls, receives results, and continues reasoning until it produces a final response—all within a **single user interaction**. |
