Key takeaways

Yan Junjie belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Yan Junjie to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Yan Junjie from memory before moving on to harder problems.

Reference excerpt

Yan Junjie (Chinese: 闫俊杰; pinyin: Yán Jùnjié; born 1989) is a Chinese businessman and the co-founder and chief executive officer of the artificial intelligence (AI) company MiniMax Group.

Early life and education Yan was born in 1989 in Henan province. He taught himself advanced calculus in high school. He attended Southeast University graduating in 2006 with a degree in mathematics. He obtained a PhD from the Institute of Automation, Chinese Academy of Sciences in 2015. During his time as a doctoral student, Yan told friends his ambition was to become a Java developer at IBM targeting an annual salary of about CN¥280,000 (US$40,000). Yan then became a postdoctoral researcher at Tsinghua University Computer Science Department with a focus on deep learning and computer vision.

Career Yan joined SenseTime as an intern in 2015 and later became vice president. In 2021, Yan left his job to found MiniMax Group. The name came from the Minimax algorithm. In January 2026, Yan attended a symposium hosted by Premier Li Qiang. The South China Morning Post described Yan as the second founder of a foundation-model developer to join such a meeting, after Liang Wenfeng.

Personal life Yan is an enthusiast of the video game Dota 2. He goes by the alias "IO", a pun on technical Input/output and a nod to the Dota wisp hero. Yan knows Cai Haoyu, the co-founder and CEO of miHoYo, through a shared interest in gaming. miHoYo was one of the early backers of Minimax Group. In 2019 he started tracking OpenAI after seeing its bots defeat the world's best players in the game. Yan has cited this as a factor in his move from computer vision to natural language processing. MiniMax Group listed on the Hong Kong Stock Exchange in January 2026. Bloomberg estimated Yan's net worth to be $3.5 billion at the time of the listing.

Worked examples

Example 1 — a first encounter with Yan Junjie

Start with the simplest possible case. Write down what Yan Junjie claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Yan Junjie before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Yan Junjie ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Yan Junjie

In research: Yan Junjie appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Yan Junjie in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Yan Junjie is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1989 births, 21st-century Chinese businesspeople, Artificial intelligence industry in China, so understanding it makes those chapters shorter.
In everyday life: Look for Yan Junjie outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
