I've just been asked to resign from the position by the North's most talented woman.

  It's the first time in the history of the world.

It was so sudden!

This morning, former OpenAI researcher Lilian Weng, an alumnus of Northern University, officially announced her resignation from TML.

She said that tomorrow will be her last day at TML.

This time, Aung San Suu Kyi did not find a good home, but decided to suspend her job due to illness.

A short internal letter saying goodbye to everything that happened.

In the comments section, Thinky's little friends wrote goodbye and congratulated her.

At the beginning of the letter, Aung San Suu Kyi apologized for being absent for a month.

12 days ago, Thinking Machines delivered one of the most important results since its inception.

The first self-developed model, Inkling, with open-source weight, native multi-models, was Mira Murati, who put real power on the stage for the first time more than a year after the release of OpenAI.

This has led to an increase in the valuation of TML to US$12 billion.

However, just as the entire team was releasing a late-night rush, Aung San Suu Kyi was on sick leave.

As co-founder, she was unfortunately absent from the first hard battle since the company was founded.

For the past seven months, I have been through the most serious period of illness in my life.

The continuous high-pressure and high-intensity work has pushed me beyond my physical limits.

She didn't want to stay.

In the letter, she said that she had seriously considered switching to a narrower role, with less responsibility and less anxiety.

But according to Aung San Suu Kyi, if you can't commit 100% to what you're responsible for, it's like not doing the job well.

So the only way to really stop is to leave completely.

He received his undergraduate degree from Peking University, completed a short-term internship at the University of Hong Kong, and earned his doctorate at Indiana University-Bermington.

After graduation, she interned at Facebook, went to Dropbox for data, and worked as a machine learning engineer at Affirm.

After joining OpenAI in 2018, she spent seven years there, completing three surprising career transitions.

Initially, as the technical head of the robotics team, she led the team to create the instant hit "Demon Engineer".

In 2021, she led a team of Applied AI researchers to refine OpenAI's APIs more strongly and easily.

In 2024, Aung San Suu Kyi was appointed vice president of security and assumed responsibility for the overall security system of the company.

Following the release of GPT-4, she was pushed to a position that almost no one was willing to take at the time.

OpenAI redesigned the entire security system architecture and integrated the scattered security work into the same team.

She describes it as "one of the hardest, most stressful, and most exciting things I've ever done".

For many in the Chinese AI community, she was known even earlier, starting with her blog Lil'Log.

She has written extensively, and many of her writings have been the first material on Transformers, Spread Models, and Agents.

The formula, "Agent = Big Model + Memory + Planning + Tool Use", is also cited by the author.

In November 2024, she gave a talk on the topic of AI security and "cultivation" at Science Super Night at Station B, comparing AI to children who need to be raised.

She left OpenAI that same month.

In February, the Thinking Machines Lab was officially announced.

It took about 20 months from the initial planning to its founding, which Aung San Suu Kyi called "a long time".

Life is not long, but in such a competitive world, it feels like the end of a lifetime.

She witnessed the displacement of her comrades.

• In October 2025, co-founder Andrew Tulloch left to join Meta.

• In January 2026, co-founder Barret Zoph, Luke Metz resigned and returned to OpenAI.

Today, four openly gay co-founders are leaving office as core members.

At the end of his farewell letter, Aung San Suu Kyi wrote a sentence: "The future worth building belongs to the people".

She used the TML declaration to pay for her departure.

As for the next stage of life, the prescription given by Aung San Suu Kyi is very specific.
