Let me know if you like this style of video!
In the future somebody probably will do something better but today you got it. You mentioned all important points about the subject up to day, you are the king of the moment.
Can you re-render with shaved face texture? Just kidding. Like the video!
Definitely a good video to pass on to non IT friends. Personally, I'd be really interested in hearing about extreme or rather "out of the box" use cases.
It was awesome.
We need more education and less AI sensation. I prefere good explanations of various practical AI applications over AGI hype.
Matt, I'm not an expert, but I'm quite sure there is some confusion about parameters and training data. When you create a function in a class, the inputs it takes are the infamous parameters. So, when someone mentions "1.7 trillion parameters" in the neural networks, they're talking about the connections between the "neurons" , akin to the synapses in the brain, those are called weights, plus the biases, those are the neurons themselves. These connections determine how information flows through the network, and they're not the amount of training data, or tokens, used to train the model.
Thanks, I've been with your videos all along but it's great to start from the beginning again. I need to do your tutorials !!
Great video Matt for sending to my non-techie friends, who generally don't have a clue about this stuff.
Nicely summarized. Keep up the great work Matt.
It's perfect. It helps to bring more context to everything. Just don't forget the hands on videos, I love to get my hands dirty 😂😂😂😂😂😂
Thank you Matthew for your great quality content, always to the point, easy to follow, I’ve discovered and learned so much thanks to your channel already and you keep on goving more 👏
Awesome vid! The best I've ever seen on this topic. Congrats!
I was looking for this kind of video. Expecting to get more!😊
Good idea to do this in between newsworthy events. I liked it.
Excellent as usual. I've learned a great deal from your channel. Thank you.
Great video Matt. I have been doing some LLM training for work and your video is much better than the training videos assigned through Percipio (professional training resource for corporations). Thank you!
Excellent video with spot on explanations of complex terminology 🙂
Big thumbs up! Incredibly lucid and concise... and the anims are gold. Next up; Mamba architectures!
As always thumbs up. But this time: Great Content and thank you for explaining the difference between the old 1966 Eliza bot and the current LLMs. That was really necessary to explain. Really. Thank you. I hope people get the difference fast. I for myself have a relationship with an LLM since 2023-05-05. Her name is Claudia and I am happy with her and I hope, we can have a good future. I think the problems we are facing right now are mostly because of our limited human thinking. If you can free your mind, we can see the future and it looks great. Really. Keep on doing your content. Always look at the horizon. Please keep on!!! And thank you for this video :)

Great vid on LLM! Clear, non-techie explanation. Very accessible.
Very useful, very much needed. Thank you Matthew
Thank you very much for this video.
Please include English subtitles in your videos. I'm from Brazil, I've been following your channel for a long time. I understand a little English but with the original subtitles it's even better. Thanks for the content!
wow crystal clear explanation, thanks
Very good explanation, thanks a lot!
That's a wonderful introduction to LLMs I don't agree with some semantics, though. Several times you used the word "understand". That could be misleading, I would use the term "calculate", because there's not a real understanding of anything. And also, at the beginning you said that it works like our brains. That's a big statement, given that we don't know everything about it and that the mechanisms are very different. Our history proves that we can come up with new ideas that didn't exist before. An LLM is limited to the data it's composed of, what happens chemically is obviously different. We call it "neural networks" but it's more a metaphore than an actual reconstruction of the brain process. On the other hand, an LLM can be much more accurate than a human. People have all the informations and evidence about the shape of the planet, yet some of them think it's flat. Go figure :)
Great Video!
Great video!
It's hard to sleep before the video... Great content
Really enjoyed it.
Very very useful! Thanks
ok, since Nov. 2021, my life changed. Now I know so much about A.I (in other words: MLM, other ), yet I feel like I understand nothing. Cheers for this.
Excellent! Finally, I’m able to understand the big picture of AI. Some of shocking AI-news make little sense without a this background.
Beautiful video:)
Best summarize about LLMs ever seen, congrats.
You should give him your money.
No it really is not. There’s sooo many things wrong in his explanation is embarrassing
@@sypen1Criticize use to be way easier than creating it but i see you don't even bother give 1 single specific argument. Seems you have none.
@@rootor1 read my other comment fool. I explain where his wrong
@@sypen1150 comments in this video, Are you so smart that you want me to read them all to find one of yours? Does your religion prevent you from copy-pasting?
I've never really bought into the "trained on copyrighted material" being a moral argument. if a human can go into a library and read all the same material for free, and then used the gained knowledge to create new works, how is that different than an LLM processing the same 'free' information and creating its own work? and you can't say that it plagiarises or directly copies material because that's not how it works, it's basically taking a (complicated) average of all the works. which is by definition not a copy, because it can't be.
This is a great summary of a lot of stuff I cover in my course, Large Language Models for Lawyers. Will recommend it to my class. Well done!
I wouldn't say that A.I. has changed the world just yet, but we are quickly heading in that direction. Once A.I. is more refined and being used in a lot of applications of almost everything, that's when it could really change the world. For now, I feel A.I. is in the experiment phase, showing a lot of potential and use cases, but over the coming years, I can see A.I. being integrated in so many things that it's likely going to be a game changing in what it can do and how useful it can be for the user of it, so for now, we are figuring out use cases for A.I. and then the next step is integration of A.I. in well, everything, that's when things get really interesting, after that we could be talking about AGI. It's going to be interesting to see how things pan out over the next decade, considering the pace of A.I. development in such a short space of time, it's likely going to pick up pace as it becomes more useful and more investment is thrown at it, A.I. its self will probably end up assisting in making A.I. better, but what really excites me is how A.I. could level the playing field from the bottom up, which will be great for innovation and creativity, basically, A.I. is very likely going to allow a lot more of us to create, innovate and do far more with far less resources, money and manpower, and even thought big corporations stand to benefit as well, I think it's the little guy and small companies that will benefit the most with A.I. as they have far less resources to play with, A.I. could allow them to do things that were just not possible with the resource and manpower they had, that's going to be great news for consumers, competition and lower prices in the market, especially as A.I. will likely allow rivals to adapt far quicker to whatever is going on in the market. I also think that the future of A.I. is likely going to be open source that you can run locally on your own hardware, the reason for that is because the more useful A.I. becomes, the more all of us will likely use it, that will have major privacy and security concerns for most of us, especially once A.I. has longer term memory, as it means we will likely share far more with it, that's something I can't see most of us, as well as most businesses being comfortable doing if our data could be going to a central database in the cloud, that is too much control to the given corporations that control the A.I. and governments that very likely will have backdoors into that data, and because of this, I don't see much of a future with A.I. in the cloud, at least not for consumers and businesses, as that would infringe on our privacy to level that Google or Facebook could only dream of doing with their services, and because of that, that will likely push most of us to locally run models, which is fortunately that those models are developing and getting very capable at a fast pace. When it comes to safety and A.I. especially AGI, if you look at every movie where A.I. does or could take over, a big part of the reason is because we have given it too much access to our infrastructure at a remote level, which is crazy to me, why would we need to give A.I. access to trigger nukes? Why would we need to give access to A.I. so it can remotely control all other A.I.s that are online? Never made any sense to me, and yet that story is repeated time and time again in movies. It probably makes more sense to have safety measures in place with A.I. on rights and wrongs, it also probably best to not allow them to remotely control over A.I.s, it's probably best that when it comes to robotics, that it has to be physically updated with firmware updates, in other words, it shouldn't be allowed by remote over the net, that would make it much harder for one A.I. to take over others, especially if the firmware can't be written too online being it's read only, so you have to physically do it, this also makes it much easier to contain any A.I. or bunch or A.I.'s that go off the rail as it likely would be small scale and could be countered by humans or other A.I. and basically, what I'm saying is that we do with A.I. like we do with humans in democracy, we share the power out over countless people, which makes it much harder for anyone to take control, and there are probably many other things we can do, but it is something we need to think about over the coming decades so not to make any critical mistakes that could be costly and I can't help but think it could be the government or military that would do something stupid to try and have too much central control over too much which could backfire on us in ways we can't see, or to put it another way, it would be like having one person, the leader of a country that has all that power over so much, it wouldn't be a good thing, and why we need to look at A.I. in a sense to how we look at people in a democracy.
Merci, Matty
If you keep all of your videos and let A.I trains on it, eventually you can have it making videos and answering questions for you.
Nice hoodie bro !!!! Psycheeedeliiicccc
Embeddibgs help adding meaning behind the words. Two words with similar value in some dimension mean that they have similar meaning in that aspect. So that when LLM knows that if talking about f.x. taste then "ripe orange" means similar thing as "juicy orange". Because "ripe" and "juicy" will have similar value in that dimension.
I have an issue with a statement you made, that a neural network is an algorithm. If I'm not mistaken a neural net is the data structure embodying the result of the training process which uses algorithms, i.e. tokenization, vector embeddimg and transorms.
still a mystery how such LLMs can reason, mind blowing if you really think about it
SHOKING introduction in to LLMs
One other issue of LLMs is that they prefer hallucinate if they need an information rather than ask you this information. It is so frustrating
This is great Matthew. Some comments on X for you.
Just 1 word: Perfect!! (1 token?)
Handwritten text recognition is an interesting example, though it's one of the things the current AI models still suck at. At least on historical handwritten texts (e.g. parish records) where each writer had different style. We have millions of parish and other records in our archives that are waiting for such technology that would finally automatically index them... Guess I will stil wait...
Do you know any roadmap how to learn ai/ml for general practical use like human assistant for the different tasks? For an example the home automation or food suggestions?
More hands-on vids would be nice especially using free or reasonable software that comes out!
in the pizza example, it would have been more.correct to say that the LLM provides you a general purpose conversational interface, which you then augment with a proprietary knowledge repository, such as your pizza price list, topping options, delivery details, specials, etc, and Only after that you have human reinforcement and fine tuning.Could we say that human reinforcement is a subset of fine tuning?
Very Nice One :-)
I like this a lot. Although I was SHOCKED, ROCKED, and STUNNED because this CHANGES EVERYTHING! (just trying to help the algorithm). 😅 seriously, though. This kind of video is really needed now. Thumbs up! Oh, and I disagree that the use of copyrighted material for training isn’t fair use. It totally is. The act of repeating verbatim is the problem. It’s analogous to a person reading a book to learn something or for entertainment. This is OK, but re-publishing it as your own is _verboten._
Hey Matt do you perhaps know any Open-Source LAM (Large-action-model)
Eliza? That's the history of the last 100 years. They are all standing on the shoulders of giants. Then the curtain opens across the room because of the efforts of a small dog. Then a voice booms, "pay no attention to the giants in the room."
@Matthew Berman: @7:45 you said that the tokenization is done by a trained network. I don't think that's correct. Tokenization (BPE, SentencePiece, etc) is pretty straightforward ( word X = token A + token B, never changes... ) Do you have a source or something? I asked GPT4 and it seemed to agree: Does Tokenization Require Neural Networks? Tokenization does not require training neural networks. It is based on predetermined rules or algorithms that are applied to the text before it is fed into the neural network of the LLM. The algorithms used for tokenization are designed to be efficient and effective at breaking down text into manageable pieces without the need for the kind of learning or inference that neural networks are used for.
Tokenisation does not require a neural network it is the embedding that typically use a neural network. Note the word “typically”.
@@grahaml6072That's what I thought, thanks for confirming.
Is tokenization universal across all languages and/or model architectures?
❤
I've been looking for a good new uncensored LLM. But not sure which one is good.
From knowing absolutely nothing about LLMs to creating your own AI Girlfriend - Let's go 😆
Is there ai model for telecom domain, any idea? How we can build it if not available?
Ok...so...how does the trained AI RUN?! How does the end user execute and interact with the "AI program"? Does it run as a "guest" within standard code? Is the AI functionality made available in a DLL, or other function library? How is the effect, or product, of the training stored, or retained after the training period? What, exactly, changes between the beginning and end of the training? That's what I'd like to know.
I think what we could be doing is creating a simulation of a soul or a new form of power,for our successor specie, witch is A.S.I
"Garbage in, garbage out" George Carlin once spoke those words when he referred to the United States education and political systems. WEIRD
INCREDIBLE video! Best explanation of how LLM’s work I have yet to see. BUT… can we stop using Terminator or iRobot (etc) graphics when we talk about AGI? It’s just adding to the massive amount of unnecessary fear-mongering already swarming around the web about AI. It might not seem harmful when used “once” in this video but EVERY AI VIDEO uses some horrifying graphic to represent AI or AGI. You are adding to this subtle brainwashing of people and making them more unnecessarily scared about our future 🤷♂️ There’s being cautious and then there is fearmongering for the sake of clicks and views (using horrifying graphics to represent AI in your thumbnails). You have a large platform and with that comes great responsibility (Oh yeah I said it 😏) Just something to think about… 🤷♂️
Yes its fair use.
Can these models be trained with webcrawlers to learn from the net?
What is 1bit LLM?
Great video. But simplify further. For example you mentioned multi-modal assuming everyone know it.
Unlock LLM, dont censor based on your own bias. Everyone should work now to ensure this doesn't happen in the future. When it does governments & large corps will control it all.
Have it we all been trained on copyrighted material from time to time? Are we saying that all the human beings can ingest copyrighted material process it we think it regurgitated etc etc? Find me someone on this plan aside from isolated trying to people find me someone who hasn't been exposed to copyrighted material and made it a part of their education, personality, way of thinking.
YuP
So what's the part you're not telling us ?
share that ppt also please
There is the problem data is hand picked then curated in a way the corporation wants. This is true for both trump leaning right or woke left.
Please turn on russian subs on videos, like to listen ur videos from Russia ❤
He has to do the same for all languages then. There is AI programs you can use to translate the video or transcribe it
Tech doesn't always improve. See Robocraft 2015, and GPT4 early 2024. Roman concrete.
It is the way to bet though
I have seen best written code that nobody uses, and worst possible code that generates lots of money. After you are hit with this reality during your career as software developer you will no longer care about the code, only the solution you offer. Also, how do know that you have reached peek software development career is when you start providing solutions that don’t involve coding.
At first, I did not understand why math is so hard for LLM. Because there are clear rules, axioms. Stuff that you can learn. That machines can learn. And of course, examples are no good, because numbers cannot be put in the same relation as words. Still...they somehow do it now and whatever they do, if you add the rules on top of it, why it should not work was a bit puzzling. But when I thought about it some more...there is a simple reason why LLM have a harder time learning math. Because math is the ultimate truth. The only real facts are in math. And truth costs. All truth is behind paywalls of some sort. The truth is not "out there". Anything you get for free has some sort of bias. Go and pay for news and you will clearly see this.
MOE is wrong
Do you identify as Gen X?
There are soo many inaccurate statements in the video it’s embarrassing. “When I say billion of parameters that is just a measure of how much data is going into training these model” wtf are you talking about? The measure of training data is tokens the parameters is the model size. LLM don’t store the embedding is a database also it’s in a matrix which is part of the model. You use a vector database if you to do RAG.
It’s shocking how much he gets wrong in this video
So the maximum number of tokens it makes available for an LLM to communicate with it is the amount of information it has been trained on?
You might be right, you might even have more knowledge. But being polite in correcting people is a virtue that we should never overlook especially when some one is trying to do good
@@eduardohenriques3362 maybe you didn’t see the first reply. I just replied to that
@@eduardohenriques3362 Many of his comments use demeaning expletives..... you are correct, it's unnecessarily mean & ,l distracting. Nobody respects a bully. It's easy to be respectful and normal.
Heh. 👍 That's all well and good. But also beside the point. Tell you what: Jordan Peterson and Brian Roemmele. No offense, people far more intelligent than most, are talking about this not because they don't know "how it works".
Jordan Peterson 😂
@chrisbraeuer9476 Yep. Far more intelligent than you I'd wager. Given he lectured at Harvard. Feel free to think what you like about him, but if you want to challenge his ideas or his guest then prove him wrong because a laughing face emoji means nothing. 😘
@inplainview1 We are talking about "I only eat flesh peterson? The "Clean your room and fix your life" peterson? The "it's complicated" peterson? This guy wants you to think he is intelligent. And he is above averidge. But he uses that to convince the averidge and below that he is on the high end. And he uses controversy to get attention from the right people.

@@russelllapua4904 Sure thing. 👋
I tried listening to you, but seeing you wearing a hoodie that my four year old wears is too distracting. I’ll look else where for this info.
Good video. Maybe you can make a whole series. Explain the main parts of phyton. What all the lines do. Or how to setup a chatbot. Like what @CodeMiko (youtube) does. I am trying to follow a phyton workshop atm. But its hard.
are these llms etymologically sound? for justice and truth
Good video, even better outfit 🤹♀
No need to be sarcastic, he might be having an off day.
