Agents are one of the most important features of Langchain and extremely fun to use.
We can give our agent an instruction, and it will use the power of LLM's and Tools to figure out the actions to take, the sequence of events and then use tools the achieve it's goals.

I absolutely love working with agents and find the reasoning aspect fascinating! Let me know what you think of agents and what the opportunities are?

Great video, like all the others in the playlist. I can't wait to see the video where you'll implement all these things with the UI.

hi, is it possible to use Ollama model and ollamaEmbeddings, then pass them as the llm and retriever tool in the createOpenAIFunctionsAgent? If not how do you create Agents based on Ollama? thanks

I tried to do something similar but using Claude 3, but I don't know if I'm not understanding correctly. Isn't there an agent that supports multitools for Anthropic?

@leonvanzyl 3 ай бұрын

Not yet, but I believe it's coming soon. OpenAI unfortunately has a monopoly on function calling, but with Mistral and Claude rolling out support for function calling this will change soon.

Great video. I'm wondering why you used in the past flowise and the OpenAI assistant and now you code everything. Is there a reason? Is there a limit in the OpenAI assistant?

@leonvanzyl 5 ай бұрын

Thank you, and don't worry. I am.working on the latest Flowise series as well 😁. Flowise is developed using Langchain, and since this is a coding channel, I also wanted to spend some time learning the underlying technology. I haven't abandoned the low-code frameworks though, and still use Flowise for my client projects. However, I had to switch over to Langchain for some bespoke solutions as well.

@@leonvanzyl thank you. I guess we can have more control on the choice of the tools by the agent. The openAi assistant doesn't always choose the right tool.

Wonderful video as usual. I am wondering why you are slowly moving to JS and not sticking with Python. Is ther ea hidden hint that JS is the future? If not, maybe getting the same tutorial in python whould be great. and if you can wrap it all with REST API (langserve?) and some web app (as opoosed to command line). sorry if I am too demanding and thanks again! Trying to help you and me :)

I had the exact same thought. Also, I wanted to experiment with pyscript and test for the issues. Do share your thoughts.

Hey there, I am creating the series in both JS and Python 😂. Check it the playlists on my channel. Herewith the link to the Python series: kzfaq.info/get/bejne/m9GgobmZktKXiXU.html

@leonvanzyl 5 ай бұрын

@@Aidev7876 Apologies. Yes, we'll create a small project where we expose our Langchain code to a web app. Probably not LamgServe at this points as it's not publicly available yet.

@leonvanzyl no worries, boss. I guess it would be stramlit or fastApi? It's important to be exposed as an API to be consumed from a chat bot lole Voiceflow, for example
