To maintain your access to the latest large language models (LLMs), ITS will release new OpenAI models on the HKU ChatGPT web app https://chatgpt.hku.hk today on 3 June 2025. These models are GPT-4.1, GPT-4.1-mini, GPT-4.1-nano, and a new reasoning model, o4-mini. At the same time, ChatGPT-3.5, GPT-4, and GPT-4o models are retired.

Additionally, following a two-month preview period, student usage of DeepSeek-R1 will start to require token deductions from the monthly balance allocated by the University.
