How to build AI Agents

Not long ago, building an AI agent capable of browsing the web, or analysing complex datasets and sorting documents required serious cost and commitment.

Today, it is achievable with a few clicks and some prompt wizardry. But while no-code tools have opened new doors, basic customization is just the first step into a much wider and more layered world.

Let’s look at the different kinds of AI agent builders now emerging, and how Griffin AI is thinking about the future of giving you more control, modularity, and true decentralization.

A spectrum from AI assistant to AI agent

Until recently you could instruct a GPT to fetch data or crunch numbers, but it remained essentially a clever script behind a smooth interface. As these systems now gain memory and plugins, the boundary between automation and true agency begins to fade. Genuine AI agents reason step by step, handling complexity within predefined limits, rather than simply executing tasks.

Griffin AI’s Transaction Execution Agent (TEA) demonstrates this shift. Griffin's TEA will check gas fees, compare exchange rates, build and submit transactions, and track them as they complete. Yet it will always stop and ask for your clear approval before money actually moves.

With this blend of independent reasoning and built-in human oversight, TEA moves closer to what real-world AI agency can safely look like. It is also a clear signal of Griffin AI’s direction in the broader landscape of AI agents.

Simple GPT customizations 

The easiest starting point comes through platforms like ChatGPT’s Custom GPTs. You don't need to code at all. You just tell it what you want your agent to do and adjust a few basic settings.

Say you want a bot that reads daily news and sends you quick summaries. In a few minutes, you can have a working agent doing just that.

This level is great for FAQs, basic customer support, or lightweight data pulls where simplicity is enough.

Enhanced GPT platforms with plugins 

Once you need your agent to interact with other services, you move to platforms that support plugins.

You can, for instance, set up a store assistant that pulls live inventory, connects to your payment system, and handles customer queries.

The extra capabilities do not add too much complexity, which is why plugin-based builders are so popular for small teams and solo creators.

Open-source AI frameworks 

Open-source frameworks like LangChain or AutoGPT are for when you want more depth and are willing to get technical.

They let you chain tasks together, design workflows, and build agents that can search databases, call APIs, and manage longer conversations. You will need some level of scripting ability, but what you can create is truly quote powerful. Griffin AI utilizes several open-source resources such as these in both our research and deployment of components such as the Builder. Open source is an excellent and vital part of the space, vital for independent developer as well as for companies building tools, research assistants, or domain-specific applications.

Enterprise-grade AI platforms 

Enterprise AI platforms like NVIDIA NeMo or Microsoft Copilot Studio provide advanced infrastructure suited to bring agent building to the corporate level.

Think automated compliance reviews, live market tracking for financial firms, or large internal knowledge systems.

Here, you get serious control over security and audit trails, but it may come at the cost of needing to pay for that dedicated development and IT support, and of having the development of your own project's systems limited by third-party controls and risks.

Self-managed AI stacks 

Fully self-managed AI stacks provide ultimate flexibility. Companies deploying these solutions might include hospitals, banks, and government agencies, going the long route of setting up private models, managing every layer of infrastructure, and locking down data governance completely.

This approach tends to offer unmatched flexibility, but demands serious investment and a full technical team that knows how to run mission-critical systems.

Griffin AI's Vision: Towards decentralized AI agent swarms

Griffin AI is on a roadmap that is about moving you smoothly along this curve, without forcing you into complexity too abruptly.

It starts simple. No-code experiences where you can shape agents easily, similar to the best parts of a GPT custom build. Our Builder will introduce advanced capabilities too, including modular agent building and task specialization, as we roll it out across the upcoming versions.

You will soon be able to plug together capabilities from the agents already live in our AI Agent Playground, creating workflows that suit what you actually need. Over time, you will be able to share them, trade them, and own them.

Our goal is to help you build not just one AI assistant, but networks of semi-autonomous agents you control — with the ability to add financial execution, market insights, and decentralized publishing.

What's next? 

The full announcement of the first Griffin AI Agent Builder is just around the corner.

We'll show you how easy it is to start crafting powerful agents with real-world capabilities, and how far you can take it when you are ready to step into the process.

Until then, dive into the agents already live in the AI Playground and start exploring.
