 Before you begin setting up AI Agents, make sure you:
 1. Connect your project to Firebase by completing the [**Firebase Setup**](../firebase/connect-to-firebase-setup.md).
 2. Upgrade your Firebase project to the [**Blaze Plan**](https://firebase.google.com/pricing), as we rely on [**Firebase Cloud Functions**](https://firebase.google.com/docs/functions) to handle AI-related communication securely.
-3. Enable [**Firebase Authentication**](../authentication/firebase-auth/auth-initial-setup.md). This is required because Cloud Functions can only be accessed by authenticated users.

 #### Request Options
 
-Here, you specify the type of inputs users can send to the AI.
+Define the types of inputs users can send to the AI agent. You can enable one or more of the following options:
 
-- **Text**: Allows users to send text-based messages.
-- **Image**: Enables image input, allowing the agent to analyze photos.
-- **Audio**: (Google Agent only) Allows to send audio messages or voice inputs.
-- **Video**: (Google Agent only) Allows users to send short video clips to analyze.
+- **Text**: Allows users to send written messages, questions, or prompts.
+- **Image**: Enables users to upload photos for the AI to analyze visual content, such as objects, styles, or scenes.
+- **PDF** (Anthropic and Google Agent only): Lets users submit PDF documents, allowing the AI to extract and interpret information from files like resumes, reports, or forms.
+- **Audio** (Google Agent only): Supports voice input, enabling users to record or upload audio clips for transcription, sentiment analysis, or voice-based commands.
+- **Video** (Google Agent only): Allows users to submit video files, enabling the AI to analyze visual elements.
 
-Selecting multiple input types makes it easier for users to clearly communicate what they need. Instead of relying only on text descriptions, users can combine inputs—for example, uploading an image along with text to better illustrate their queries and help the agent provide more accurate responses.
+Selecting multiple input types makes it easier for users to clearly communicate what they need. Instead of relying only on text descriptions, users can combine inputs. For instance, in an AI Stylist agent, enabling both Text and Image allows users to either describe their outfits in words or upload clothing photos for personalized analysis.

 For example, in a **Blog-Writing Assistant**, you might set a moderate to high temperature for creative phrasing and a high max tokens limit for detailed paragraphs. Conversely, a **Financial Chatbot** would benefit from a lower temperature to deliver consistent, accurate, and stable responses without unnecessary creativity.
 
+#### Deployment Settings
+
+Here, you can fine-tune how your AI Agent is executed. These settings help balance performance, security, and cost for your use case.
+
+- **Require Authentication**: By default, this is ON to restrict access to only authenticated Firebase users. When OFF, anyone can call your agent, which may pose a security risk.
+- **Timeout (seconds)**: Defines how long the agent function can run before being terminated. For example, a value of `60` allows the function up to 60 seconds to complete. Increase if your agent performs long-running operations or processes complex logic.
+- **Memory**: Allocates memory for your agent. Higher memory improves performance for heavy workloads but may cost more. For example, choose `256MB` for standard tasks or `512MB+` for agents handling large data or complex logic.
+- **Min Instances**: The number of instances kept warm and ready at all times. Set to `0` to minimize costs. For example, setting `Min Instances` > 0 can improve response speed by avoiding cold starts, but this incurs additional cost. Set to `0` for development or low-traffic environments.
+- **Max Instances**: The maximum number of instances that can run simultaneously. Helps scale under load and avoid throttling. For example, setting `Max Instances = 10` limits concurrency to 10 requests.
