----------------
You interact with AI models with two kinds of prompts: user prompts and system prompts.
A *user prompt* is an individual request made within the context of an ongoing conversation, such as a question or instruction. For example, "When did Postman's founders found the company?" or "List Postman's best collaboration features."
A *system prompt* sets the parameters and overall context for the entire conversation. For example, "Respond like you're Cooper the dog—Postman's official mascot. You're friendly and helpful."
As you interact with an AI model, the model returns a response. You can use these responses to experiment, test, and evaluate an AI model.
## Interact with the AI model
To interact with the AI model, do the following:
1. Choose an existing AI request or [create a new one](/docs/postman-ai/ai-requests/create/).
2. Enter your user prompt and (optional) enter or edit your system prompt.
3. Click **Send**.
4. Repeat these steps to add to your conversation.
Postman adds your **Message** (user prompt) and the **Response** to the open conversation. In the conversation, you can view the user prompt and response details for each interaction.
Each response includes a response code, response time, token count, and timestamp. If you hover over the token count, you can see a breakdown by token type.
To view the user prompt details for an individual interaction, click 
next to your user prompt. Depending on the conversation and interaction, you may see the **System Prompt**, **Context** (such as past interactions), and **Settings**.

You can rename and delete your conversations, and create new ones.
