Welcome to this second unit, where **we'll explore different agentic frameworks** that can be used to build powerful agentic applications.
|
|
|
|
We will study:
|
|
|
|
- In Unit 2.1: [smolagents](https://huggingface.co/docs/smolagents/en/index)
|
|
- In Unit 2.2: [LlamaIndex](https://www.llamaindex.ai/)
|
|
- In Unit 2.3: [LangGraph](https://www.langchain.com/langgraph)
|
|
|
|
Let's dive in! 🕵
|
|
|
|
## When to Use an Agentic Framework
|
|
|
|
An agentic framework is **not always needed when building an application around LLMs**. They provide flexibility in the workflow to efficiently solve a specific task, but they're not always necessary.
|
|
|
|
Sometimes, **predefined workflows are sufficient** to fulfill user requests, and there is no real need for an agentic framework. If the approach to build an agent is simple, like a chain of prompts, using plain code may be enough. The advantage is that the developer will have **full control and understanding of their system without abstractions**.
|
|
|
|
However, when the workflow becomes more complex, such as letting an LLM call functions or using multiple agents, these abstractions start to become helpful.
|
|
|
|
Considering these ideas, we can already identify the need for some features:
|
|
|
|
* An *LLM engine* that powers the system.
|
|
* A *list of tools* the agent can access.
|
|
* A *parser* for extracting tool calls from the LLM output.
|
|
* A *system prompt* synced with the parser.
|
|
* A *memory system*.
|
|
* *Error logging and retry mechanisms* to control LLM mistakes.
|
|
We'll explore how these topics are resolved in various frameworks, including `smolagents`, `LlamaIndex`, and `LangGraph`.
