Musk loves and is back to OpenAI!
Andrej Karpathy, former Tesla AI senior executive and former head of Autopilot, FSD and more, announced his next job 7 months after leaving Tesla: joining OpenAI (again).
Yes, it's OpenAI, the ChatGPT company that is now on fire.
After all, Karpaz's first job after graduation was to study computer vision at OpenAI.
Later, Musk, one of the co-founders of OpenAI, took a fancy to Karpas and poached people to Tesla. But also because of this incident, Musk and OpenAI completely fell out, and finally was kicked out.
Karpas left Tesla for the time being, saying that he would focus on AI, open source and technical education for the time being, and now returned to OpenAI.
We also asked ChatGPT what they thought of Karpas joining again, and it said:
"Andrej Karpathy's rejoining OpenAl is important for the AI community and research community, and can have a beneficial impact on the future development of AL."
Karpas announces his entry to OpenAI
Karpas joined this time, and as he announced his departure from Tesla before, clockwork Twitter briefly said.
"Some personal message: I'll be joining OpenAI (again :)). I'm inspired by the impact of their work, just like others inside and outside the field of AI. I'm especially excited about the future potential of OpenAI and excited to be back working with you all! ”
Below his tweet, OpenAI CEO Sam Altman and the company's research scientists both said, "Welcome back! ”
In case anyone doesn't know much, OpenAI is an American artificial intelligence research company, founded in 2015 by Altman, Musk and others, with the goal of developing friendly AI in ways that benefit all of humanity.
The now popular ChatGPT, as well as DALL-E, GPT-3, etc. are all AI models launched by OpenAI. Take ChatGPT as an example, simply put, this is an AI chatbot, which can answer various questions in natural language, and even help people write code, design, and poetry...
ChatGPT is trained through reinforcement learning, and when Karpas worked at OpenAI, in addition to recruitment, he was also responsible for studying deep learning and deep reinforcement learning of models.
During his Ph.D., Karpas was mainly engaged in the research of deep learning algorithms for computer vision and natural language processing.
At the time, OpenAI was a small non-profit company. After Musk met Karpas here, he felt that it was a pity that such a good talent was placed in OpenAI, so he poached people to Tesla.
In 2018, Musk was kicked out of OpenAI's board, claiming that the AI studied by Tesla would have a conflict of interest with OpenAI, but in fact, it was because Musk dug into the wall.
And Karpas' contribution to Tesla proves that Musk is not a loss in poaching.
Karpas at Tesla
In 2017, Karpas joined Tesla, first working on neural networks and computer vision, under Jim Keller, vice president of hardware engineering at Autopilot.
At this time, Tesla was preparing to abandon Mobileye and wanted to develop its own computer-vision-driven assisted driving system.
Jim Keller left and Karpas was promoted by Musk to take over the Autopilot team, mainly in charge of software, and Pete Bannon in charge of hardware.
It is also under the leadership of these two that Tesla FSD was born, which has also been Tesla's core selling point for a long time.
The team led by Karpas is mainly responsible for data collection and neural network training, that is, responsible for training the vital vision systems in Autopilot and FSD, using the data collected by the camera to make high-definition three-dimensional maps and judge the driving environment around the vehicle.
Karpas laid the foundation for the development of Tesla's Autopilot and FSD, so to speak.
And Musk also continues to delegate heavy responsibilities to Karpasia, not only serving as the core speaker of AI Day for many times, Tesla humanoid robots and supercomputing Dojo are also projects he has been responsible for.
However, in April last year, it was revealed that Karpas was on a four-month long vacation, which also made people worry that he would leave, after all, Doug Field, a former senior engineer at Tesla, never returned after taking a vacation.
Karpas himself came forward to explain that he has been working for almost 5 years and wants to rest and travel to relax. At the same time, he will focus on self-improvement during the holidays, but will come back, he misses Tesla's robots and Dojo.
But people's fears are also justified, and in July last year, he tweeted his departure from Tesla.
Musk also made a rare gesture: Thank you for everything you have done for Tesla, it is my honor to work with you.
Although Karpas left without warning, from Karpas's education experience, perhaps OpenAI's job will be more suitable for him.
Karpas: I want to make humanity happy
Karpas's experience is actually a bit similar to Musk.
Born in Czechoslovakia in 1986, he immigrated to Toronto, Canada with his family at the age of 15, and successfully entered the University of Toronto, graduating with a double bachelor's degree in computer science and physics in 2009. Musk was born in South Africa, then immigrated to Canada, and first studied in Canada for a period of undergraduate.
Karpas then studied computer science at Columbia University, earning a master's degree in 2011.
During his undergraduate years, Karpas first encountered deep learning, but did not delve into it, just felt that "something magical would happen to the training data." While in his master's degree, he took a course on machine learning, his first deeper understanding of neural networks and other models.
He was very interested in artificial intelligence at first, so he took a course on artificial intelligence, but he was not very satisfied with artificial intelligence's depth-first search, breadth-first search, etc., probably because most people will discuss artificial intelligence.
In general, humans are responsible for writing code, but in machine learning it is written by computers, humans are responsible for optimization, and can establish input and output specifications, and sometimes machines write code better than humans.
Karpas felt that this was a very new way of thinking about programming, and that was the area that was really interesting, and this was the kind of artificial intelligence he wanted to spend time working on.
So in the doctoral stage, Karpas studied under the familiar AI master Li Feifei, focused on the intersection of natural language processing and computer vision at Stanford, as well as deep learning models suitable for the task, and obtained a doctorate in 2015.
During his Ph.D., Karpas personally designed and taught a course called "CS231n: Convolutional Neural Networks for Visual Recognition" and served as the main lecturer.
The class became one of the largest at Stanford, with 150 students enrolled in the class in 2015 and 750 by 2017.
Karpas himself confessed that he was a full-fledged night owl when he was studying for a Ph.D., often going to bed at three in the morning, or even later.
This time is a good working time for him, because during the day there will be all kinds of news, news, etc. to distract him, and he is not disturbed when he wants to solve the problem.
And he doesn't think he likes teaching, although he's happy to help others. He only likes happy people, including when he is writing code he thinks repeatedly, will other people appreciate it? Will they like the results?
This is also the impetus for Karpas to continue to work in machine learning-related fields, Karpas once said:
"If I'm helping humans, they're happy seeing my work, and they've been discussing things I'm researching, it makes me happy because I'm doing something useful."
He loves to see others get value and joy from what he creates, and he loves that feeling.
As mentioned earlier, OpenAI was established to benefit all mankind and develop human-friendly AI; Recent ChatGPT has shown great practicality in programming, drawing, writing poetry, planning, etc., which makes many people think that AI can be so easy to use.
Now it seems that I don't know if the frequent accidents of Tesla Autopilot and FSD have affected Karpas's choice, but his choice to join OpenAI again at least shows that he still wants to use his business to benefit mankind.
One more thing
For Andrea Karpas to join OpenAI again, we also asked ChatGPT for its opinion.
ChatGPT says:
Well, then look forward to it.
