What are AI Agent Frameworks?

AI agent frameworks refer to starter kits that help organizations build their own AI agents. It provides a structure that enables normal AI models to understand context, plan actions, execute, and communicate without depending on operators. 

You can take an AI agent framework as an assembly kit, which provides users with tools and components to build autonomous agents. These AI agent frameworks provide an interface to the real-world environment in which agents must perform. 

Along with this, they give a knowledge base to the AI agents, which stores data and helps in making decisions. Reasoning engines add logic to their working mechanism, while executor makes them capable of actually carrying out the tasks. 

In short, an AI agent framework works like a builder kit that helps create agents. These agents possess the following characteristics:

Perception

AI agents are capable of gathering data and understanding the context from it. This contributes to its element of autonomy, as it gives it an idea of what the situation is and what needs to be done in the situation.

Autonomy

AI agents possess autonomy, meaning that they do not need someone to guide them; they can autonomously carry out tasks. This makes carrying out operational tasks easy and more efficient.

Decision-Making

As mentioned already, AI agents have autonomy and perception ability. These abilities make them capable of making decisions on their own without waiting for human intervention. They can understand the need of a situation and create action plans by themselves.

Adaptability

AI agents are not rigid to a certain working mechanism; they can adapt their working mechanism and action plan as and when needed. They possess adaptability, which makes them capable of bending and mending their action plans according to situations.

Collaboration

Collaboration is yet another characteristic of AI agents. It reflects the ability of AI agents to collaborate with humans and with other agents. This means that AI agents can work as a team, whether with other agents or with human operators.

What is AgentKit?

AgentKit is a complete agent-builder kit launched by OpenAI. This kit allows enterprises to build their own AI agents. It removes the hassle of juggling between multiple tools and complicated workflows by giving a kit that handles everything from building AI agents to testing and deploying them. OpenAI’s agentkit consists of:

  • Agentbuilder: This lays a canvas where enterprises can define their AI agents and the kind of workflows they want their agents to handle. It outlines how all the agents will carry out their tasks and collaborate with each other.
  • Connector Registry: As the name suggests, the connector registry is the point where all the connection points(areas where agents will connect) are defined. These include data sources, APIs, databases, etc.
  • ChatKit: ChatKit allows enterprises to create a layer where users can connect to the agents. It creates a point of connection without actually having to build one; it provides a pre-built interface.
  • Evals: Evals provide tools that facilitate testing of the built AI agents. It allows enterprises to compare their planned agents and actual ones to find deviations and fix them before deployment. 

Benefits of AgentKit

Cost Efficiency 

Since AgentKit offers pre-built frameworks to developers, it reduces the cost that organizations spend on building agents from scratch. AgentKit offers no-code agent builder tools. It saves time and costs spent on allotting both monetary and human resources to create agents manually. 

Limitations of AgentKit

Every coin has two sides, and every framework has its own benefits and drawbacks. But what are the drawbacks of AgentKit? That’s exactly what’s coming next. Here are some of the limitations of AgentKit:

Heavy Reliance on OpenAI Stack

AgentKit limits the exposure during development to OpenAI’s stack. This means that using AgentKit for developing AI agents limits enterprises’ ability to connect to alternative AI models from other providers. If a certain feature offered by another provider is better, organizations won’t be able to access it.

Limited Customization

As mentioned already, AgentKit offers pre-built structures for building AI agents. While these pre-built structures do make the development process quick and easy, they limit customization in the AI agents. This means that if enterprises want to add a customization factor in their AI agents, they will need to write custom code.

Beta Components

Many components in the AgentKit, like the connector registry, are beta versions. This means that they are still under development and might go through improvements and changes. These beta components create a sense of uncertainty in the minds of developers about the output quality.

Basic Evaluation Tools

The evaluation tools offered by AgentKit may reflect basic compared to other tools available. This means that the testing that these tools carry out might not be very advanced. They may lack in testing highly customized agents and large-scale ones.

What Is LangChain? 

LangChain is a versatile framework powered by Large Language Models(LLMs). LangChain is not limited to AI agent development; it provides abstractions that help developers build a variety of platforms. 

To break it down simply, you can think of LangChain as a toolkit that offers pre-built building blocks. These blocks help in connecting LLMs to data, APIs, and workflows. LangChain gives AI models the ability to utilize tools, interact with the environment, and grasp context without actually having to build it all. It makes LLM integration simpler by eliminating the need for manual code writing. LangChain consists of the following components:

Language Modules

Language modules are the components that provide output by understanding the language. These modules power the logical engines of AI models. They make the models capable of grasping the context of a situation by interacting with the environment. 

Prompt Templates

Prompt templates are reusable structures that transform user input to interpret it for the language models. It helps users save time and effort that would otherwise be spent writing prompts from scratch.

Memory

Memory, as is obvious, stores all the data of the past, recent, and ongoing interactions. It’s a database that saves all the data that the AI agent goes through or collects while working on giving an output.

Retrieval Modules

Retrieval modules are the components that help the AI agents in retrieving information from the database. It helps the AI agents in giving an accurate response by going through all the knowledge sources and retrieving the data that’s most relevant to the query.

Agents

An agent is the component that can understand the need of a situation, plan a course of action to fulfill the need, and execute the plan it makes. The agent is capable of deciding what task to do, what tools to utilize, and the workflow on how to get it done. 

Benefits of LangChain

LangChain, as an AI agent framework, brings in multiple benefits for organizations. It helps in developing AI agents faster, allows extensive tooling and integration support, high customization, and cost transparency. Sounds interesting, right? Let’s break down these benefits in detail:

Quick Development Process

LangChain makes the process of developing AI agents quick and easy, as most of the components, like prompts, databases, etc, are already available. Enterprises need not create AI agents from scratch. All they have to do is gather the required components and combine them as per their needs.

Extensive Tooling and Integration Support

LangChain is not limited to a certain set of tools; it allows developers to access a wide variety of tools be it from other providers as well. Along with this, it makes agents capable of interacting with the environment, different knowledge sources, workflows, etc. It does so by providing integration support.

High Customization

Customization is yet another benefit that enterprises can unleash by using LangChain for AI agent development. The framework allows developers to create custom agents. It does not restrict developers to a certain design. This helps them decide the logical reasoning, response pattern, working mechanism, and interaction span of the agents. 

Cost Control and Transparency

As mentioned already, LangChain allows enterprises to make use of tools from various providers. This means that organizations can opt for different models that meet their quality as well as monetary requirements. And since the choice for model usage is in the hands of the organization, LangChain gives them transparency throughout the development process.

Limitations of Langchain

While LangChain does bring in a whole lot of benefits, it carries its own share of limitations as well. But what are those? The limitations of LangChain include complexity, setup effort, and scalability constraints. Let’s understand them better with a deeper dive into the limitations:

Complex for New Users

While LangChain does make AI agent development easy, it can turn out to be quite complex for new users. It requires actual coding to create AI agents. This makes it hard to be accessed by users who are not familiar with such technicalities.

High Setup Effort

Developing AI agents using LangChain often requires high setup effort. It is so because the process requires working on prompts, vector stores, tools, memory modules, and sometimes custom logic. This not only takes up manual effort but costs time as well.

Complexity in Multi-Agent Designs

When building multi-agent designs, the complexity of the development process multiplies, too. This is because when developers work on creating multiple agents, they have to define their workflows, responses, and capabilities. And since all of this is carried out manually, the task naturally becomes complex.

Scalability Constraints

While LangChain does help organizations scale their agents but it does not automatically solve scaling challenges. It requires the user to carry out the scaling processes by handling underlying models, databases, etc. This additional work makes scalability a limitation for the LangChain framework.
