The full narration of the video.

Among people who code with AI, one name keeps popping up: Tibo. He runs core products at OpenAI. His full name is Thibault Sottiaux. First, Codex. It's OpenAI's coding assistant: say what you want, and it writes the code.

But you can't use it without limit. Your allowance works like two batteries. One covers five hours, the other a whole week. When they run out, you wait. But when Tibo posts that he's reset the limits, everyone's batteries refill at once.

Why reset? Sometimes it's an apology — when the service slows down or breaks. Other times it's a celebration — a new model launches, and everyone gets to try it freely. Fans built a website to track it. As of September 26th, 57 resets have been verified.

But there's no schedule. Anyone who says he resets every Friday is guessing. So next time someone shouts "Tibo reset again!" you'll know: everyone's AI batteries just refilled together.

The short version

Tibo is the head of product at OpenAI. The moment he posts "reset," everyone's AI usage allowance refills to full.

His full name is Thibault Sottiaux; Tibo is what everyone calls him.

First, meet Codex

BEFORE
Programmers type it themselves
One feature, one afternoon.
Codex
Say it, and the AI writes it
A coding assistant made by OpenAI: you say what you want, and it edits the code and tries it out.

Handy, but not unlimited. Like a phone data plan, there's an allowance in your package.

The allowance is like two batteries

Small battery: 5 hoursUse it hard and it runs out first, then slowly refills by itself after a while.
Big battery: one weekThe total for the week. Once it's empty, you wait until next week.
Tibo resets itNo waiting: both batteries are instantly full again. For everyone at once.

Why does he reset it?

Something broke: make it up to everyoneIf the service got slow, had errors, or mistook normal use for abuse, a reset is the compensation.
Good news: invite everyone to tryWhen a new model launches or a milestone is hit, a reset lets everyone try freely.

Fans built a dedicated website to track it: as of the reset on September 26, 57 resets have been verified.

What it's not

Not a regular perkThere's no schedule. Anyone who says "he resets every Friday" is just guessing.
Not a marketing campaignIt isn't tied to the marketing or finance teams. The people who build the product make the call themselves.
Not a permanent upgradeIt only refills this round's allowance early. The plan itself hasn't changed.
Next time someone in the group chat shouts "Tibo reset it again,"
you'll know: everyone's AI batteries
just refilled together.

Where AI model names come from

Claude, GPT, Gemini, Qwen: every model name is three pieces — whose it is, how big, which version. And each brand has a story.
