From a research lab to a household name
OpenAI was founded in 2015 as a research lab. The GPT series made next-word prediction feel like conversation. ChatGPT arrived in late 2022 and taught the world to ask a model out loud. GPT-4 raised the ceiling. GPT-4o folded speech, vision, and text into one product people already call ChatGPT. Whisper, DALL·E, and Advanced Voice are part of that same public story.
GPT-4o as a family, not a single inbox
GPT-4o is the flagship people mean when they say ChatGPT today: strong at talk, at a picture prompt, and at a spreadsheet cleanup. GPT-4o mini is the lighter twin for a short turn. On this rail those strengths are not one dump. Voice writes the script you can say. Images writes the still. Sheets owns formulas, pivots, and a dirty table.
Why Wrooms split the assistant
A mixed inbox is how topics leak. A spoken turn should not become a Midjourney prompt. A VLOOKUP should not become a Claude preview. Each desk on this rail has its own page so you can pin the craft you actually want.
How to ask ChatGPT here
@voice to hear a script. @image for a still. @sheets for the grid. Pin the desk when the room should stay on that job. A fact-check is Facts. A long 中文 brief is Kimi. A preview that opens is Artifacts.
