Are you curious about AI but feel overwhelmed by coding? Fear not! This step-by-step beginner’s guide will show you how to build your first AI agent with no prior experience. By the end of this tutorial, you’ll have a functional AI agent complete with a model, memory, and tools—all set to handle workflows or even power advanced projects.
🧠 What is an AI Agent?
An AI agent is like a digital assistant that can interact with you and perform tasks based on your inputs. It’s made up of three key components:
- Model: The “brain” of the agent, generating responses.
- Memory: Helps the agent “remember” previous interactions.
- Tools: Extends the agent’s functionality to fetch data or perform tasks like sending emails.
👨💻 Step 1: Setting Up the AI Agent
Start by opening a new workflow and adding a trigger to execute your workflow. Choose the “On Chat Message” trigger, so your AI responds to messages.
Next, add an AI agent from the tool options. For this tutorial, we’ll use a tools agent, leaving other settings as default.
🧩 Step 2: Adding the Model
Your AI agent needs a chat model to generate responses. Think of this as the “brain” of the operation. For simplicity, we’ll use Mistral’s Nemo model—a lightweight, free-to-use option.
Set up credentials on Mistral’s website, grab your API key, and paste it into the workflow. Select “Nemo” as your model. Now, your agent is ready to process messages!
💾 Step 3: Giving Your Agent a Memory
Out of the box, AI agents can’t remember past conversations because they are stateless. Adding a memory component solves this problem.
- Choose Window Buffer Memory for simplicity.
- Set the context length (default: 5 messages). This ensures your AI recalls recent exchanges while staying efficient.
Test it out: Tell the agent your name, then ask it to recall it. With memory in place, your AI will successfully “remember” you!
🌐 Step 4: Adding Tools
Tools allow your AI to go beyond basic chat capabilities. Let’s add two tools:
- Wikipedia Tool
- This fetches the latest information, ensuring your AI provides up-to-date responses.
- For example, ask about a recent event, and the AI will pull the latest details from Wikipedia.
- Gmail Tool
- Use this to send emails directly from your chat!
- Configure Gmail credentials, set the recipient, subject, and message, and let your AI handle the rest.
Test these tools to see how they seamlessly extend the agent’s capabilities.
🎉 Your AI Agent is Ready!
Congratulations! You’ve built an AI agent with a model, memory, and tools. It can now chat intelligently, remember past interactions, pull real-time information, and even send emails.
