Use of ChatGPT at EdUHK 

EdUHK has adopted a chatbot-based large language model (LLM), using Microsoft Azure AI Services, that generates text or images in dialogue format so as to facilitate the University community to embrace the technology. Hosted on campus, the service provides similar functionality to OpenAI’s ChatGPT. According to Microsoft, unlike other AI tools such as OpenAI, we do not record your conversation history for any future AI model training. Colleagues may delete their conversation history at their own discretion at any time while students’ conversation history is kept on the University server for record purposes, e.g. for course instructor’s review if necessary.  Please read and accept the terms and conditions of using ChatGPT at EdUHK before using the service. 

EdUHK staff and students are provided with DeepSeek-R1, DeepSeek-V3, o3-mini, GPT-4o, GPT-4o mini and DALL·E 3. They can access and experience the AI tool at https://chatgpt.eduhk.hk/ with their network account and password. Each user is given a monthly credit of 1,500,000 units to use the chatbot service. 

Self-service Credit Top-up Function for Students

Students can conveniently purchase additional credits through the Online Payment Portal (OPP) and the credits are instantly added to the purchased credit balance upon completion of the transaction. They can purchase up to 3,000,000 credits per transaction. The system will automatically use the monthly free credits first before deducting from the purchased credits. While these credits have no expiration date, they are non-transferable and non-refundable. Students should not purchase more than needed. To purchase additional credits, log into the EdUHK ChatGPT platform and click “Top up” in the menu bar. To check your top-up history, please see “My Orders” on OPP.

Note: Since our service is based on Microsoft Azure AI Services, the provision of our service may be subject to changes in Microsoft’s technology, policies, and terms of service. We will make every effort to inform you of any changes that may arise.

Please note that other generative AI tools such as POE (https://poe.com/) from Quora and Copilot (https://copilot.microsoft.com/) from Microsoft are hosted by external parties. Colleagues are therefore advised to avoid disclosing confidential, sensitive or personal information, especially if you are not sure how the data is kept or used. As a general principle, please opt for our service, if confidential, sensitive or personal data is to be used. Again, it is best to remove or mask sensitive data before using any AI tools.

Terminology

There are some new terms used and below are a few to help you get started.

1. Prompts / Queries - Your text input to get what you want it to do.
2. Completions / Responses - The return for your prompt / query.  
3. Credit Units - The lengths and consumptions of the prompt / query and completion / response are calculated in terms of tokens by Microsoft Azure AI Services. Tokens can be words or just chunks of characters. (Please see https://learn.microsoft.com/en-us/azure/cognitive-services/openai/overview#tokens for more details.) The amount of tokens consumed is more than just counting the words in your current prompt because it also needs to consider your previous conversations.
4. There are a few models available now. Users should choose the model to use according to individual needs. 
   

   Model	Credit consumption speed / Credit consumption (as of Mar 2025 and is subject to changes)
   ChatGPT (GPT-3.5) - 16k context (general-purpose assistant chatbot) (no longer available for use from 1 Nov 2024)	1.00x
   DeepSeek-R1 (text only) (advanced reasoning model for math, coding and problem-solving)	5.40x
   DeepSeek-V3 (text only) (powerful model for coding, multilingual tasks and language understanding)	4.56x
   o3-mini (text only) (newer and more cost-efficient reasoning model)	4.40x
   GPT-4o - 128k context (chatbot that supports input of text and up to four images in one prompt)	11.00x
   GPT-4o mini - 128k context (chatbot that supports image processing capabilities and is more cost-efficient)	0.66x
   DALL·E 3 (chatbot for the generation of digital images that last for 2 days in the conversation)	28,000 units per image output

   

Other Generative AI Tools

There are other generative AI tools on the market, such as the following. Colleagues are advised to avoid disclosing confidential, sensitive or personal information in the prompt / query when using these tools.

1. Microsoft Copilot
   Open a web browser and access https://copilot.microsoft.com/.
2. Quora POE
   Register the free service of POE by accessing https://poe.com/. You need to provide your email address or phone number to complete the registration. POE also supports mobile devices running iOS or Android. Download it from https://poe.com/download/.

Please observe the 6-P pedagogical approach promulgated by the University earlier (https://www.lttc.eduhk.hk/papers/6p.pdf), which promotes the productive use of AI-enabled text-generating tools for the development of critical and/or reflective thinking by students.
