This release introduces two new model versions for PhoenixAI users. These updated models will more accurately interpret prompts and use improved reasoning to fulfill user queries. The service will also be updated to be HIPAA compliant.

New Features

Compliance Features

HIPAA Compliance for PHI: This release introduces HIPAA compliance support for Personal Health Information (PHI) through the creation of a new security role: PHI Restricted. PhoenixAI must meet the data security requirements defined by the University Medical Center for handling PHI. To help ensure compliance, the PHI Restricted role limits entitlements for users who access PHI.

Features not currently available to users who work with PHI:

• GPT model o3-mini
• Internet Search
• Share Thread
• Share Assistant With Everyone
• Share Assistant With Group

Splash Screen For PHI Restricted Users: A new login screen appears the first time a PHI Restricted User logs into PhoenixAI. The screen outlines usage conditions and requires the user to click Accept & Continue before proceeding. After initial acceptance, the splash screen will not appear on future logins.

• PhoenixAI Terms of Use for Health Information Users
  • By accessing this generative AI application, you acknowledge and agree to the following terms:
    1. LIMITATION: This system may not be used for clinical decision-making, patient care, or any purpose outside approved research protocols.
    2. APPROVED USE: This system is strictly for authorized academic researchers who have completed the required HIPAA and research ethics training.
    3. CONFIDENTIALITY: All interactions with this system containing health information must remain confidential. Do not share outputs, screenshots, or system access with unauthorized individuals.
    4. DATA SECURITY: While this system employs security measures to protect against health information leakage, you are responsible for ensuring appropriate data handling in your interactions.
    5. COMPLIANCE: Usage must comply with the University’s data security policies, and all applicable research protocols.
    6. MONITORING: System usage is monitored for system health, compliance and security purposes only.
    7. NO WARRANTY: This system is provided "as is" without a warranty of any kind regarding accuracy, completeness, or reliability of outputs.

Group Based Access for Assistants

• A ServiceNow request form is being introduced to request group-based access for Assistants.
• Note: Only faculty and staff who are not PHI Restricted Users are eligible to submit this form.
• Access requests involving large student groups (e.g., all students in a course) must be made by faculty or staff. Students may still create assistants and manually share access with a limited number of individuals (e.g., 10 classmates and their instructor).
  

System Initiated Deletion of Threads/Chats, Assistants, all Associated Files

PhoenixAI is committed to protecting user privacy, including the specific needs of protecting health information. To support this, all inactive threads, assistants, and related data for PHI Restricted users will be automatically deleted after 90 days of inactivity. These data retention requirements will begin mid September, 2025.

Threads/Chats and all Associated Files

• Threads/Chats and all Associated Files
  • Non PHI Restricted Users - 365 days from last response date
  • PHI Restricted Users - 90 days from last response date
•  Assistants and all Associated Files
  • Assistant Creator is not a PHI Restricted User - 365 days from last activity date
  • Assistant Creator is a PHI Restricted User - 90 days from last activity date

Chat Retention 

You can choose to automatically delete inactive threads and chats after a specified period of inactivity. When enabled, any thread/chat that remains inactive for the selected number of days will be permanently deleted and cannot be recovered. Use the Active toggle/slider to enable this feature and enter the number of days (1–90) for custom automatic deletion, click Update to save your settings. A chat is considered inactive if no new prompt has been entered during the specified time period.

Internet Search

PhoenixAI now includes an Internet Search feature that allows the assistant and individual chats/threads to access up-to-date information. When this option is disabled, responses are based only on existing knowledge and may not include recent events. When enabled, the assistant can search the web to provide more current answers, including clickable source links showing where the information came from. An assistant creator can turn off Internet searches from their Assistant to focus searches only on internal knowledge and uploaded knowledge files.

For example, if you ask about a recent news event:

• With Internet Search disabled, the assistant may not provide a relevant or updated answer.
• With Internet Search enabled, the assistant can retrieve and display information from recent sources

You can experiment with the Internet Search toggle to see how it affects the assistant's responses. Please note: Always validate the results and cross-reference the sources provided to ensure accuracy. The Internet Search setting follows your current configuration when creating a new assistant. By default, it is disabled. If you enable it, that setting will persist for all new chats and assistants until you choose to disable it again. 

Please note that only the GPT-4.1 model has access to Internet Search. This feature is not available in the o3-mini model as seen in the images below.

Dark Mode

Dark Mode is now available. You can enable the Dark Mode theme by navigating to Settings > General and toggling it on. This feature provides a darker interface that may be easier on the eyes, especially in low-light environments. Dark mode theme can be set to be “System, Light, or Dark. This setting is connected to your PhoenixAI profile.

New Features

Review this section to see what new functionality has been added to PhoenixAI in this release.

Incognito Mode

• Incognito Mode Creation and Features: Users can create temporary threads in incognito mode, which are not stored or displayed in their history. A visible indicator will show that incognito mode is active, and users can access a description of the feature. An incognito session is limited to 30 minutes from when the first prompt is entered. However, a new session can always be created.
• Restricted Functionality in Incognito Mode: While in incognito mode, elements like the sidebar, Assistants, and custom buttons are disabled, but links such as PhoenixAI Help and the UChicago logo remain active. The sidebar will also be marked as disabled for screen readers. Lastly, incognito threads cannot be shared.
• Thread Deletion and Non-Restoration: Incognito threads and files will be deleted upon exiting incognito mode, closing the application, closing the browser tab, or at the end of 30 minutes. These deletions are permanent and cannot be restored or exported.
• Incognito Mode Limitations: Users are unable to switch from an existing thread to incognito mode or convert an incognito thread to a regular chat. Only one incognito thread can be active at a time, and new incognito threads can be created while the mode is active.

Assistants

• Formerly known as Custom MyGPTs, are now referred to as Assistants.

Thread Sharing

• When sharing a thread, the recipient will only be able to see the chat up to the point in time when the thread was shared.
  • All subsequent prompts that the original user enters will not be shared.
• Only authenticated users can access shared threads, and they cannot edit the thread.
  • Additionally, the shared thread recipient will be unable to view any files created or uploaded.
• The original author of the shared thread will delete all of the shared versions of that thread when deleting it.
• Importantly, shared threads expire after 16 weeks from the shared thread link's creation date.

Archive Threads

• Users can archive threads to remove them from the sidebar, with the option to unarchive them from a settings menu.
• Users can still delete threads they created from the sidebar menu.
• Archived threads can be found and managed through the settings menu.
• Archiving a thread will not affect the view of shared thread recipients, and the "Hide Thread" option will appear in the UI when archiving.

Rename Threads

• Users can rename threads in their thread history (sidebar menu) to assign a personalized title.
• Renaming a thread created by the user will not affect the title of the shared version, as shared threads are not live.

Hide/Unhide Assistants

• Users can hide Assistants they created or those shared with them from the sidebar, with the ability to unhide them later.
• Hidden Assistants can be found and managed by the user.
• Hiding and unhiding functionality applies to both user-created and shared Assistants.
• Hiding a shared Assistant from the sidebar does not affect the view of the user who received it.

Settings

• Settings Screen Overview: A new settings screen allows users to update preferences, including managing archived chats and customizing chat settings. It also includes sections for data retention and chat archiving.
• Archived Chat Management: The settings screen allows users to view, search, delete, and unarchive archived threads. A confirmation message appears when deleting all threads.
• Shared Thread Management: Users may view and delete threads shared with others or shared with them, with the option to delete threads shared by others.
• Assistants Management: The settings menu includes options to hide or unhide Assistants the user has created or been shared with. Users can also delete their own Assistants or those shared with them. However, deleting an Assistant shared with a user only deletes their copy and not the original. 

Search Feature

• Search Functionality: The search button allows users to find threads based on keywords, and searches only thread titles, not content. Search is case-sensitive. 
• Archived Thread Search: Search includes visible and archived threads.

Chart/Graph Generation

• Used to generate images of charts and graphs based on the data received, not to create images of people, places, or objects.
  • The data received must be in text or file format (i.e. .csv, Excel) and in a tabular format.
  • If asked to generate images other than charts and graphs (e.g. a picture of a park on a sunny day), users are recommended to use Copilot.

Chart/Graph Output

• Charts and graphs are generated and displayed onscreen with an option to download in PNG (.png) format.

Image Analysis

• PhoenixAI will analyze uploaded images, providing a description of the image. When prompted, PhoenixAI can also display ALT text in a separate, copyable output.
• Supported image formats include PNG (.png) and JPG (.jpg).
• GPT-4o is the only model capable of image analysis.
• Only one image file (max 20 MB) can be uploaded at a time, and video files are not supported in this release.
