Generative AI vs. Agentic AI: What's the Difference?
AI tools are everywhere now, and it's easy to hear the term "Agentic AI" and wonder how it's different from the AI you're already used to, like a chatbot. The short version: generative AI answers you when you ask it something, while Agentic AI can go off and complete a task for you, in several steps, mostly on its own. This article explains the difference in plain language, with real examples you can try on your own Bluehost server.
What is Generative AI?
Generative AI is what most people picture when they think of "AI." You type a question or a request, it gives you an answer, and that's it. If you want something else, you ask again.
A good way to picture it: generative AI is like a very knowledgeable helper who is happy to answer any question you ask, but who waits for you to ask before doing anything. It won't take action on its own, and it won't remember what you talked about once the conversation ends.
What is Agentic AI?
Agentic AI is a step beyond that. Instead of just answering a question, it can take a goal you give it and figure out, on its own, all the steps needed to get there. It can use other apps, complete a series of tasks, and keep working with little to no extra input from you.
Think of it like handing a task to a helpful assistant and saying, "take care of this for me," instead of giving instructions one step at a time. This is why Agentic AI tools are often connected to messaging apps, business tools, or other software. They don't just talk, they act, for example, replying to a message on WhatsApp, running a scheduled task overnight, or working together with other AI agents to finish a bigger job.
Key Differences at a Glance
| Aspect | Generative AI | Agentic AI |
|---|---|---|
| How it works | Answers one question or request at a time | Plans and completes multi-step tasks on its own |
| Independence | Waits for you to give it every instruction | Figures out the next steps by itself |
| Takes action | Only gives you text, images, or answers | Can use other apps and get things done for you |
| Memory | Usually forgets everything once the chat ends | Can remember things and keep working across sessions |
| Best for | Quick questions and one-off tasks | Ongoing jobs and background work |
Everyday Examples
- Generative AI: You ask a chatbot to write a product description or answer a question, and it hands you the result right away.
- Agentic AI: You ask an AI agent to "handle my customer messages," and it reads incoming chats, replies to common questions, and only asks for your help when something is unusual.
Examples of Generative AI
These are available as one-click installs on Bluehost Self-Managed VPS and Virtual Dedicated Server (VDS) plans. Together, they let you ask a question and get an answer back, the same way you would with a familiar chatbot, except everything runs privately on your own server. Each one plays a slightly different role in making that happen:
| App Name | What It Does |
|---|---|
| Open WebUI | The actual chat window you type into. This is the part that looks and feels like a chatbot. |
| Ollama | The engine running behind the scenes that loads an AI model and generates the answers. You don't interact with it directly; it works quietly in the background to power the chat window. |
| DeepSeek | An AI model, essentially the "brain" that Ollama runs, which is what actually understands your question and comes up with a response. |
In other words, DeepSeek is the brain, Ollama is what runs that brain on your server, and Open WebUI is the chat window you actually see and type into. Installing all three together gives you your own private, chatbot-style AI, similar to using ChatGPT, but hosted entirely on your own server.
Examples of Agentic AI
These tools are also available as one-click installs on the same Bluehost Self-Managed VPS and VDS plans. Unlike the tools above, they can carry out tasks over several steps, often continuing to work in the background.
| App Name | What It Does |
|---|---|
| Claude Code | An AI helper for writing and fixing code. It can look through your files, make changes, and test that the changes work, without needing you to guide every step. |
| OpenClaw | A personal AI agent you host yourself. It connects to apps like WhatsApp and Telegram, so it can chat with you and complete tasks right from your messaging app. |
| GatorClaw | A simple, visual way to build your own AI agents without needing to write any code. It's designed to be easy for small business owners to set up. |
| Nanoclaw | Lets you run your own AI assistant that connects to WhatsApp and Telegram, so it can handle chats and tasks for you right in those apps. |
| Hermes Agent | An AI agent that remembers past conversations and tasks, and can be set up to run the same jobs automatically, like a daily report or recurring reminder. |
| Hermes Agent + Open WebUI | Combines Hermes Agent with a simple chat window, so you can talk to your agent the same way you'd chat with any AI tool. |
| Paperclip | Lets you set up a whole "team" of AI agents that work together on a project, each with its own job to do. |
| Sim | A visual, drag-and-drop tool for building AI agents that can complete tasks and connect with the other apps and tools you already use. |
| Langflow | Another visual tool for building AI agents by connecting pieces together on screen, without needing to write code. |
| Dify | A platform for building your own AI-powered apps and agents, useful if you want to create a custom AI tool for your business. |
| BMAD | A framework that organizes multiple AI agents into roles, similar to a small team, to work through a project step by step. |
| n8n | A tool for connecting your apps and services together so tasks happen automatically, for example, saving a form submission straight into a spreadsheet. |
Why This Matters to You
Knowing the difference helps you pick the right tool. If you just need a quick answer or a piece of text, a generative AI chat tool like Open WebUI (paired with Ollama and a model like DeepSeek) does the job. If you want something to run in the background and handle a task for you over time, like managing messages or automating a workflow, an Agentic AI tool like OpenClaw, Nanoclaw, or n8n is the better fit.
One thing to keep in mind: Agentic AI tools usually need a bit more ongoing setup, since they connect to other apps, messaging platforms, or services and often keep running in the background. Generative AI chat tools are generally quicker to get talking to once installed, since it's mainly a matter of connecting the chat window to a model.
Summary
In short, generative AI answers when you ask. Agentic AI can take a task and run with it. Neither one is "better," they're just built for different jobs. Bluehost's Self-Managed VPS and VDS plans let you try either kind with a one-click install, so you can pick whichever fits what you're trying to do.
