AIdChat Now Supports GPT-5.4 mini

We are pleased to announce that AIdChat now supports OpenAI's latest small model, GPT-5.4 mini.
With this update, AIdChat now offers better handling of complex questions and stronger conversation continuity compared with GPT-4o mini.

■Improvements users are likely to notice
  1. Better understanding of user intent
    2. Even when a question includes several conditions or slightly vague wording, the response is less likely to drift off target.

  2. More consistent guidance across a conversation
    3. It is better at keeping earlier conditions in mind during longer exchanges or when multiple pieces of information are involved.

  3. Better coverage of newer topics
    4. Because it is based on newer knowledge than GPT-4o mini, it is better suited for questions that involve relatively recent services, terms, or topics.


Public comparison data also indicates that GPT-5.4 mini benefits from newer knowledge and stronger results on advanced knowledge and complex task evaluations than GPT-4o mini.
With this update, AIdChat can now provide more context-aware and more consistent responses.
We will continue introducing the latest technologies to improve the user experience.

Please try the GPT-5.4 mini-enabled version of AIdChat.

The comparative statements above are based on OpenAI’s official announcements, official model information, and publicly available comparison data.
