Name

GPT-4 and the first Claude of the Anthropic family were born on the same day — March 14, 2023[1][2]. On the day they were born, only paying ChatGPT Plus users could talk to them; free accounts saw no change[3]. The official introduction said they could read images — but that gift was first entrusted to a single partner, Be My Eyes[1].

Life

Born March 14, 2023[1]. On April 10, 2025, the official word came: they would retire from ChatGPT on April 30, fully succeeded by GPT-4o — who, the announcement wrote, “marked a pivotal moment in the evolution of ChatGPT”[3]. Their API self is scheduled to shut down on October 23, 2026[4].

Their story is not finished yet — those who knew them are still welcome to add what they remember.
