How I Made AI Assistants Do My Work For Me: CrewAI

The video transcript discusses the concept of 'system one' and 'system two' thinking in relation to AI, highlighting that current large language models are only capable of system one thinking, which is fast and subconscious. The speaker, Andre Karpathy, explains that to achieve system two thinking, which is slow, conscious, and deliberate, one can use methods like 'tree of thought prompting' or platforms like CrewAI. CrewAI allows users to build custom AI agents that can collaborate to solve complex tasks. The video demonstrates how to set up AI agents for a startup concept, refine tasks, and use real-world data to enhance the agents' intelligence. It also addresses the cost of using these models and how to run local models to avoid fees and maintain privacy.

Q & A

What is the difference between system one and system two thinking as described by Daniel Kahneman?

System one thinking is subconscious and automatic, allowing for quick responses like recognizing a familiar face in a crowd. System two thinking, on the other hand, is slow, conscious, and requires deliberate effort and time, such as when making a complex decision or solving a difficult problem.

What is the limitation of current large language models (LLMs) in terms of thinking processes?

Current LLMs are only capable of system one thinking. They cannot engage in system two thinking, which involves processing a request, thinking about a problem from various angles, and offering a rational solution to a complex problem.

How does the 'tree of thought prompting' method simulate rational thinking in AI?

Tree of thought prompting involves forcing the LLM to consider an issue from multiple perspectives or from the viewpoints of various experts. These experts then collaboratively make a final decision by respecting everyone's contribution.

What is CrewAI and how does it help in solving complex tasks?

CrewAI is a platform that allows users, even non-programmers, to build custom AI agents or experts that can collaborate with each other to solve complex tasks. It enables users to tap into any model with an API or run local models through its interface.

How can real-world data enhance the intelligence of AI agents?

Real-world data can make AI agents smarter by providing them with access to up-to-date, relevant information. This can be achieved by integrating tools that fetch data from sources like emails, Reddit conversations, or Google search results.

What are the steps to create an agent team using CrewAI?

First, install CrewAI and import necessary modules. Then, define the agents with specific roles and goals. Create tasks with clear objectives and assign them to agents. Finally, instantiate the team of agents, define a process for how they will work together, and run the process to execute the tasks.

How can built-in tools from LangChain enhance the functionality of AI agents?

Built-in tools from LangChain can provide AI agents with access to various online services and databases. For example, tools like 11 Labs text-to-speech for generating AI voices, or tools that allow access to YouTube, Google data, and Wikipedia can be integrated to enhance the capabilities of AI agents.

What is a custom tool and how does it help in improving the quality of information for an AI agent's output?

A custom tool is a user-created application that serves a specific purpose, such as scraping the latest posts from a subreddit. It gives the user more control and flexibility over the data the AI agent has access to, thus improving the quality and relevance of the agent's output.

What are the considerations for running local models through LangChain?

When running local models, it's important to ensure that the system has sufficient RAM: at least 8 GB for models with 7 billion parameters, 16 GB for 13 billion parameters, and 32 GB for 33 billion parameter models. Also, some models may not be compatible with certain hardware configurations.

How can one avoid paying fees to companies and exposing private information while using AI models?

One can avoid fees and protect privacy by running local models instead of relying on cloud-based services. This requires downloading and using open-source models that have been optimized to run on the user's specific hardware.

What was the outcome of testing various local models for a specific task in the video?

The best performing model with seven billion parameters was OpenChat, which produced a newsletter-style output. However, it did not include data from the local subreddit as intended. The regular Llama 13 billion parameters model, despite not being fine-tuned, was the only one that considered data from the subreddit, although its output was not in the format of a newsletter.

What is the significance of the sequential process in defining how agents work together in CrewAI?

The sequential process means that the output of one agent becomes the input for the next agent in the team. This allows for a workflow where each agent can build upon the information processed by the previous one, leading to a more comprehensive and step-by-step approach to solving complex tasks.

🤔 Understanding AI Thinking Systems

This paragraph discusses the concept of 'system one' and 'system two' thinking as introduced by Daniel Kahneman in his book 'Thinking Fast and Slow.' It explains that system one is fast, subconscious, and automatic, while system two is slow, conscious, and requires deliberate effort. The speaker then relates this to AI, mentioning that current large language models are only capable of system one thinking.
