You can interact with an AI model 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 the AI model, the model returns a response. You can use these responses to experiment, test, and evaluate an AI model.
To interact with the AI model, do the following:
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.
Important: Conversations aren't saved and won't be available after you close an AI request. If you want to preserve your conversations, keep the AI request open.
