Sam Altman posted something cryptic on X last night: "here is a little hint: 🎁" Turns out it's a hidden ChatGPT feature. Here's how it works: How to Try It 1. Open ChatGPT and start a new chat 2. Send just the gift emoji: 🎁 3. It'll ask you to upload or take a selfie 4. Sora (OpenAI's video tool) generates a short personalized Christmas video of you The video pulls from your previous ChatGPT conversations to personalize it. Santa tells you whether you've been naughty or nice based on what ChatGPT knows about you. You don't get to choose the style or what happens—it just creates something based on your history with the tool. A Few Things to Know - Looks like it's one video per person (trying again gives you the same one) - Other holiday emojis like 🎅 and 🎄 might also trigger it - The more you've used ChatGPT, the more tailored the result The Marketing Angle Worth noting how OpenAI launched this: no announcement, no campaign. Just a single emoji post that got people curious enough to figure it out themselves. I hope you can see how they leverage Altmans personal brand. If you try it, share what you got in the comments.
