# Input nodes

Input nodes are the starting point for most agents. They define what information users provide when running your agent — text instructions, reference images, video files, audio clips, or documents.

### Tips

* **Keep inputs minimal.** Every input is friction for the end user. Only ask for what the agent actually needs.
* **Combine inputs with Text Assistants.** Place a Text Assistant node after your inputs to merge and structure multiple inputs into a single clean prompt before it hits your AI generation node.
* **Label your inputs clearly.** Rename input nodes to describe what the user should provide (e.g., "Product photo" instead of "Upload Image").&#x20;
* **Use Upload File for rich context.** A PDF brand book gives the AI far more context than a short text prompt — connect it to a Text Assistant to extract the relevant information.
