  6. 0:19All right. Most explanations of AI
  7. 0:20agents is either too technical or too
  8. 0:23basic. This video is meant for people
  9. 0:26like myself. You have zero technical
  10. 0:28background, but you use AI tools
  11. 0:30regularly and you want to learn just
  12. 0:33enough about AI agents to see how it
  13. 0:36affects you. In this video, we'll follow
  14. 0:38a simple one, two, three learning path
  15. 0:41by building on concepts you already
  16. 0:43understand like chatbt and then moving
  17. 0:46on to AI workflows and then finally AI
  18. 0:49agents. All the while using examples you
  19. 0:52will actually encounter in real life.
  20. 0:55And believe me when I tell you those
  21. 0:56intimidating terms you see everywhere
  22. 0:58like rag, rag, or react, they're a lot
  23. 1:02simpler than you think. Let's get
  24. 1:04started. Kicking things off at level
  25. 1:05one, large language models. Popular AI
  26. 1:08chatbots like CHBT, Google Gemini, and
  27. 1:10Claude are applications built on top of
  28. 1:14large language models, LLMs, and they're
  29. 1:17fantastic at generating and editing
  30. 1:19text. Here's a simple visualization.
  31. 1:21You, the human, provides an input and
  32. 1:24the LLM produces an output based on its
  33. 1:27training data. For example, if I were to
  34. 1:29ask Chachi BT to draft an email
  35. 1:31requesting a coffee chat, my prompt is
  36. 1:33the input and the resulting email that's
  37. 1:36way more polite than I would ever be in
  38. 1:37real life is the output. So far so good,
  39. 1:40right? Simple stuff. But what if I asked
  40. 1:43Chachi BT when my next coffee chat is?
  41. 1:47Even without seeing the response, both
  42. 1:49you and I know Chachi PT is gonna fail
  43. 1:52because it doesn't know that
  44. 1:53information. It doesn't have access to
  45. 1:56my calendar. This highlights two key
  46. 1:58traits of large language models. First,
  47. 2:00despite being trained on vast amounts of
  48. 2:02data, they have limited knowledge of
  49. 2:04proprietary information like our
  50. 2:07personal information or internal company
  51. 2:09data. Second, LLMs are passive. They
  52. 2:12wait for our prompt and then respond.
  53. 2:14Right? Keep these two traits in mind
  54. 2:17moving forward. Moving to level two, AI
  55. 2:19workflows. Let's build on our example.
  56. 2:21What if I, a human, told the LM, "Every
  57. 2:25time I ask about a personal event,
  58. 2:26perform a search query and fetch data
  59. 2:29from my Google calendar before providing
  60. 2:31a response." With this logic
  61. 2:33implemented, the next time I ask, "When
  62. 2:35is my coffee chat with Elon Husky?" I'll
  63. 2:38get the correct answer because the LLM
  64. 2:40will now first go into my Google
  65. 2:42calendar to find that information. But
  66. 2:45here's where it gets tricky. What if my
  67. 2:48next follow-up question is, "What will
  68. 2:50the weather be like that day?" The LM
  69. 2:53will now fail at answering the query
  70. 2:55because the path we told the LM to
  71. 2:57follow is to always search my Google
  72. 3:00calendar, which does not have
  73. 3:02information about the weather. This is a
  74. 3:04fundamental trait of AI workflows. They
  75. 3:07can only follow predefined paths set by
  76. 3:10humans. And if you want to get
  77. 3:12technical, this path is also called the
  78. 3:15control logic. Pushing my example
  79. 3:17further, what if I added more steps into
  80. 3:20the workflow by allowing the LM to
  81. 3:22access the weather via an API and then
  82. 3:24just for fun use a text to audio model
  83. 3:26to speak the answer. The weather
  84. 3:28forecast for seeing Elon Husky is sunny
  85. 3:31with a chance of being a good boy.
  86. 3:33Here's the thing. No matter how many
  87. 3:35steps we add, this is still just an AI
  88. 3:39workflow. Even if there were hundreds or
  89. 3:41thousands of steps, if a human is the
  90. 3:44decision maker, there is no AI agent
  91. 3:47involvement. Pro tip: retrieval
  92. 3:49augmented generation or rag is a fancy
  93. 3:52term that's thrown around a lot. In
  94. 3:54simple terms, rag is a process that
  95. 3:56helps AI models look things up before
  96. 3:58they answer, like accessing my calendar
  97. 4:00or the weather service. Essentially, Rag
  98. 4:03is just a type of AI workflow. By the
  99. 4:06way, I have a free AI toolkit that cuts
  100. 4:07through the noise and helps you master
  101. 4:09essential AI tools and workflows. I'll
  102. 4:10leave a link to that down below. Here's
  103. 4:12a real world example. Following Helena
  104. 4:14Louu's amazing tutorial, I created a
  105. 4:17simple AI workflow using make.com. Here
  106. 4:19you can see that first I'm using Google
  107. 4:21Sheets to do something. Specifically,
  108. 4:23I'm compiling links to news articles in
  109. 4:25a Google sheet. And this is that Google
  110. 4:28sheet. Second, I'm using Perplexity to
  111. 4:31summarize those news articles. Then
  112. 4:34using Claude and using a prompt that I
  113. 4:36wrote, I'm asking Claude to draft a
  114. 4:38LinkedIn and Instagram post. Finally, I
  115. 4:42can schedule this to run automatically
  116. 4:44every day at 8 a.m. As you can see, this
  117. 4:46is an AI workflow because it follows a
  118. 4:49predefined path set by me. Step one, you
  119. 4:52do this. Step two, you do this. Step
  120. 4:55three, you do this. And finally,
  121. 4:57remember to run daily at 8 am. One last
  122. 4:59thing, if I test this workflow and I
  123. 5:02don't like the final output of the
  124. 5:05LinkedIn post, for example, as you can
  125. 5:08see right here, uh, it's not funny
  126. 5:10enough and I'm naturally hilarious,
  127. 5:11right? I'd have to manually go back and
  128. 5:16rewrite the prompt for Claude. Okay? And
  129. 5:20this trial and error iteration is
  130. 5:23currently being done by me, a human. So
  131. 5:25keep that in mind moving forward. All
  132. 5:27right, level three, AI agents.
  133. 5:29Continuing the make.com example, let's
  134. 5:31break down what I've been doing so far
  135. 5:33as the human decision maker. With the
  136. 5:36goal of creating social media posts
  137. 5:37based off of news articles, I need to do
  138. 5:39two things. First, reason or think about
  139. 5:43the best approach. I need to first
  140. 5:44compile the news articles, then
  141. 5:46summarize them, then write the final
  142. 5:48posts. Second, take action using tools.
  143. 5:51I need to find and link to those news
  144. 5:53articles in Google Sheets. Use
  145. 5:55Perplexity for real-time summarization
  146. 5:58and then claw for copyrightiting. So,
  147. 6:00and this is the most important sentence
  148. 6:01in this entire video. The one massive
  149. 6:04change that has to happen in order for
  150. 6:06this AI workflow to become an AI agent
  151. 6:09is for me, the human decision maker, to
  152. 6:13be replaced by an LLM. In other words,
  153. 6:16the AI agent must reason. What's the
  154. 6:19most efficient way to compile these news
  155. 6:20articles? Should I copy and paste each
  156. 6:22article into a word document? No, it's
  157. 6:24probably easier to compile links to
  158. 6:26those articles and then use another tool
  159. 6:28to fetch the data. Yes, that makes more
  160. 6:30sense. The AI agent must act, aka do
  161. 6:34things via tools. Should I use Microsoft
  162. 6:37Word to compile links? No. Inserting
  163. 6:39links directly into rows is way more
  164. 6:41efficient. What about Excel? M. So the
  165. 6:44user has already connected their Google
  166. 6:45account with make.com. So Google Sheets
  167. 6:47is a better option. Pro tip. Because of
  168. 6:49this, the most common configuration for
  169. 6:51AI agents is the react framework. All AI
  170. 6:55agents must reason and act. So
  171. 6:59react. Sounds simple once we break it
  172. 7:01down, right? A third key trait of AI
  173. 7:03agents is their ability to iterate.
  174. 7:06Remember when I had to manually rewrite
  175. 7:08the prompt to make the LinkedIn post
  176. 7:10funnier? I, the human, probably need to
  177. 7:13repeat this iterative process a few
  178. 7:15times to get something I'm happy with,
  179. 7:17right? An AI agent will be able to do
  180. 7:19the same thing autonomously. In our
  181. 7:22example, the AI agent would autonomously
  182. 7:25add in another LM to critique its own
  183. 7:28output. Okay, I've drafted V1 of a
  184. 7:30LinkedIn post. How do I make sure it's
  185. 7:32good? Oh, I know. I'll add another step
  186. 7:34where an LM will critique the post based
  187. 7:36on LinkedIn best practices. And let's
  188. 7:38repeat this until the best practices
  189. 7:40criteria are all met. And after a few
  190. 7:42cycles of that, we have the final
  191. 7:45output. That was a hypothetical example.
  192. 7:47So let's move on to a real world AI
  193. 7:50agent example. Andrew is a preeeminent
  194. 7:53figure in AI and he created this demo
  195. 7:55website that illustrates how an AI agent
  196. 7:58works. I'll link the full video down
  197. 8:00below, but when I search for a keyword
  198. 8:02like skier, enter the AI vision agent in
  199. 8:07the background is first reasoning what a
  200. 8:10skier looks like. A person on skis going
  201. 8:12really fast in snow, for example, right?
  202. 8:14I'm not sure. And then it's acting by
  203. 8:18looking at clips in video footage,
  204. 8:22trying to identify what it thinks a
  205. 8:24skier is, indexing that clip, and then
  206. 8:29returning that clip to us. Although this
  207. 8:32might not feel impressive, remember that
  208. 8:34an AI agent did all that instead of a
  209. 8:36human reviewing the footage beforehand,
  210. 8:39manually identifying the skier, and
  211. 8:42adding tags like skier, mountain, ski,
  212. 8:45snow. The programming is obviously a lot
  213. 8:47more technical and complicated than what
  214. 8:49we see in the front end, but that's the
  215. 8:51point of this demo, right? The average
  216. 8:53user like myself wants a simple app that
  217. 8:56just works without me having to
  218. 8:58understand what's going on in the back
  219. 9:00end. Speaking of examples, I'm also
  220. 9:02building my very own basic AI agent
  221. 9:05using Nan. So, let me know in the
  222. 9:07comments what type of AI agent you'd
  223. 9:08like me to make a tutorial on next. To
  224. 9:11wrap up, here's a simplified
  225. 9:12visualization of the three levels we
  226. 9:14covered today. Level one, we provide an
  227. 9:17input and the LM responds with an
  228. 9:19output. Easy. Level two, for AI
  229. 9:22workflows, we provide an input and tell
  230. 9:24the LM to follow a predefined path that
  231. 9:27may involve in retrieving information
  232. 9:29from external tools. The key trait here
  233. 9:31is that the human programs a path for LM
  234. 9:34to follow. Level three, the AI agent
  235. 9:37receives a goal and the LM performs
  236. 9:39reasoning to determine how best to
  237. 9:41achieve the goal, takes action using
  238. 9:44tools to produce an interim result,
  239. 9:46observes that interim result, and
  240. 9:48decides whether iterations are required,
  241. 9:51and produces a final output that
  242. 9:53achieves the initial goal. The key trait
  243. 9:56here is that the LLM is a decision maker
  244. 9:58in the workflow. If you found this
  245. 10:00helpful, you might want to learn how to
  246. 10:02build a prompts database in Notion. See
  247. 10:04you on the next video. In the
  248. 10:05meantime, have a great one.
