Recently, Large Language model (LLM) is getting more attractions all over the world. Google released their new LLM called “PaLM 2” on 10 May 2023. It starts competing against “ChatGPT” which was released in Nov 2022 and attracts over 100 million users in just two months. LLM is expected to be more intelligent in a short period as competition between big IT companies is getting tough. What does it mean to us? . Let us consider step by step!

1. How can we create our own agent?

In my article in Feb 2023, I said AI can be our agent which understands our languages. Let us consider how it is possible step by step. When I want to eat lunch. I just order my agent, saying “I would like to have lunch”, LLM can understand what I say and try to order my favorite hamburger at the restaurant. For LLM to act against the outside world (such as call restaurants), it needs some tools, which can be created with libraries such as “LangChain”. Then LLM can order my lunch and finally I can have lunch, anyway. It sounds good. Let us move deeper.

2. LLM is not just an “interface” to us with natural languages.

As I said in Feb this year, the first time I used ChatGPT, I felt like it could understand what I said. But now I do not think it is just an“interface” any more. Because LLM is trained with massive amounts of text from the web, books and other sources, LLM obtains a lot of knowledge of human beings from the past to the present. Since Chat GPT appeared in front of us last year, I performed many experiments with LLM and found that LLM has an ability to make decisions. Although it is not perfect, it sometimes performs at the same level as human beings. It is amazing! In addition to that, LLM is still in the early stage and evolves on a daily basis!

3. LLM will be more and more intelligent as a “reasoning engine”!

Mr. Sam Altman, OpenAI CEO says in youtube “ChatGPT may be a reasoning engine”(1). I completely agree with his opinion. When we create our agents, LLM works as a “reasoning engine” to make decisions to solve complex tasks. Around LLM, there are many systems to act against the outside world, such as “search web” or “shop in e-commerce”. All we have to do is think “how can we enable LLM make the right decisions”. Because LLM is very new for everyone, no one knows the right answer. Fortunately, LLM can understand our languages, it may not need programming anymore. It is very important for us. So let us consider step by step!

I would like to update the progress of AI agents. Stay tuned!
