This model can simultaneously understand and process a variety of multimodal inputs, including text, images, voice, and video. For example, if you upload a photo, it can ask, “What is this?” or if you show it a picture of food, it can even tell you the recipe.

Real-time voice response is also possible, enabling natural conversations where a person can respond in about 0.3 seconds. Calculation accuracy, code writing ability, memory, and translation ability have all been greatly enhanced.

2) Real-time web search function (Pro only)

It can search and answer questions from the web in real time, including the latest news, when needed. For example, if you ask, “What is the hottest news in the US today?”, it can tell you the latest news.

3) Dramatically expanded memory function – April to June 2025

This feature remembers the user's information and preferences and automatically applies a customized conversation style and writing tone.

This feature will be available to Plus/Pro users starting April 10, 2025, and will be extended to Free accounts starting in June.
