Holy crap, the god of resets, Tibo, actually got reassigned and reset himself?!

According to the latest Reuters news, Tibo has now been transferred to take charge of OpenAI's internal system security project;

and the one who may have taken the baton from him is none other than Andrew Ambrosino, a founding team member of the Codex App.

As soon as the news broke, onlookers rushed to Andrew's comment section and immediately started assigning tasks to the presumptive "successor."

Someone first spoke up on behalf of Plus users, hoping OpenAI would take them seriously too;

someone begged for Chat and Work not to be merged, and someone else simply demanded the removal of the five-hour usage limit, along with opening Dots to Plus users.

That's right, Andrew, once you're on the job you'd better press that reset button a lot!! The more the better! (expectation.jpg)

Why was Tibo suddenly sent off to do security?

According to Reuters, what Tibo has taken on this time is actually a rather important security engineering effort inside OpenAI.

For years, OpenAI employees have raised concerns about internal operational security, including overly broad access to sensitive code, insufficient security review of internal tools, and potential insider threats, among others.

Just this October, OpenAI even had a very outrageous security incident exposed—

an engineer not only secretly installed eavesdropping equipment in an executive meeting room, but also hid a recording device inside toilet paper, and was ultimately prosecuted by U.S. federal law enforcement.

Now, OpenAI is determined to start systematically closing these security gaps.

Reuters, citing people familiar with the matter, reported that as early as August this year, Tibo had already deployed about a quarter of OpenAI's production engineers to participate in security infrastructure construction.

Moreover, Tibo himself has now begun publicly talking about his new job!

Just moments ago, he personally reposted OpenAI's latest cybersecurity research results and excitedly announced:

We have built a world-class cybersecurity team, and I look forward to sharing more of our work in the coming weeks and months.

And looking back a bit, this job change seems to have had traces all along.

Just six days ago, right after Tibo announced doubled usage quotas for Pro 100/200/500 and Business Premium users, he suddenly announced:

I'm graduating from the "reset company" and moving to the "token company"!

At the time, everyone thought Tibo was just doing his daily bit again and didn't take it too seriously.

But then Tibo turned around and shared a post by Andrew Ambrosino, specifically telling everyone:

If you have any friendly feedback, send it to this person.

At the same time, Andrew also publicly announced:

The doubled usage quotas for paid tiers such as Pro 100/200/500 and Business Premium have been restored.

Not only that, he also revealed that he would personally supervise the team's new round of focused sprint work and greatly improve the simplicity and performance of the ChatGPT app.

Tibo also specifically instructed Andrew, hoping the models would keep getting better, because they still can't do everything yet.

Andrew immediately responded:

Got it, I'll get right on it!

Good grief, the more these two talk, the more it looks like an old leader handing over work to a new colleague before leaving.

However, OpenAI has not yet officially announced that Andrew has fully taken over Tibo's previous responsibilities;

but judging from product feedback and app improvements, at least this newcomer has already stepped up to the forefront on his own initiative.

The baton-passing Andrew is actually also an old acquaintance of Codex

Andrew Ambrosino graduated with a bachelor's degree from UMass Lowell, majoring in computer science with minors in business, mathematics, and design.

As early as during college, he had already joined MITRE to work in software and design engineering, and in 2013 he served as a software engineering intern at Microsoft.

In 2016, he simply went into entrepreneurship himself, founding a fintech company called Catch, and served as CTO/CPO for seven years straight.

By 2023, he had moved on to Noyo, where he successively handled front-end engineering, design, and product business.

In 2025, Andrew officially joined OpenAI and became one of the core team members of the Codex App.

After that, he gradually led the Codex App team, and his scope of work further expanded to the ChatGPT app.

Looking at it this way, Andrew can be said to be a very typical triple-threat player across engineering, design, and product.

And recently, from announcing the restoration of doubled usage quotas, to personally supervising the simplification and performance improvements of the ChatGPT app, to publicly inviting netizens to offer feedback and a series of other actions, Andrew has also begun taking on more and more user demands that originally flooded toward Tibo.

It's just that what everyone misses most is probably still that familiar reset button. (doge)

After all, in Tibo's hands, everyone had long been spoiled into a bit of a habit.

I really hope Andrew can inherit this "ancestral craft," and on his first day on the job happily smash that reset button and let us go all out!
