ChatGPT was released by OpenAI on November 30, 2022, as a productized application of the GPT lineage.

Summary

This pins down the specific day OpenAI put a polished, consumer-facing chatbot in the world, turning the GPT research line into something regular users could actually talk to. It serves as a fixed timeline anchor, so any reasoning about who was where in the AI race, when competitors responded, or how the technology matured gets measured against that date.
