Building Your Own Langchain Agents and Tools with LLMs: A Step-by-Step Tutorial

The video is about Developing Custom Langchain Agents and Tools using LLMs

The code used in this note book is at

The steps to create Custom Agents re
EASIEST ROUTE IS TO USE LLMCHAIN WITH ZEROSHOT
AGENT. PROMPTS MAKE ALL THE DIFFERENCE
PROMPT TEMPLATE WITH BELOW PARTS
TOOLS: LIST OF TOOLS THE AGENT WILL HAVE ACCESS TO, USED TO FORMAT THE PROMPT.
PREFIX: STRING TO PUT BEFORE THE LIST OF TOOLS.
SUFFIX: STRING TO PUT AFTER THE LIST OF TOOLS.
INPUT_VARIABLES: LIST OF INPUT VARIABLES THE FINAL PROMPT WILL EXPECT.
CREATE LLM CHAIN WITH PROMPT
USE ZERO SHOT AGENT ON THE LLMCHAIN
USING AGENTEXECUTOR.RUN METHOD TO EXECUTE

The steps to create the tools are
TOOLS ARE MADE OF PYTHON FUCTIONS + LLMS
NAME (STR), IS REQUIRED
DESCRIPTION (STR), IS OPTIONAL
FUNCTION, TO EXECUTE
RETURN_DIRECT (BOOL), DEFAULTS TO FALSE
TOOLS ARE CHAINED TOGETHER USING INITIALIZEAGENTS
PYTHON CLASSES CAN BECOME A TOOL BY INHERITING
BASETOOL CLASS
PYTHON FUNCTION CAN BECOME A TOOL BY USING THE
TOOL DECORATOR

The Colab notebook will provide excellent playground to practice these concepts. Use the same, and learn how to build your own tools. Do subscribe to the channel for updates on the videos.

Good luck working out the audio driver.l In the meantime as always great job! I appreciate your passion for teaching and sharing your knowledge🏆🎉

Apart from the audio, your content is very good.

One question though. CAN I use Langchain for Zero Shot Text Classifier??
Is there an already existing agent for it or can I create one?

I would really like to follow your videos but the terrible audio quality does not make it easier for me to understand (greetings from Germany)

C'mon dude you can build a custom llm agent but can't figure out audio recording..?
