AI Agents vs. Large Language Models: What’s the Difference?

terry 13/08/2025

If you’re still using large language models (LLMs) like ChatGPT just for chatting, you’re missing out. Over the past six months, AI has evolved into something far more powerful: AI Agents.

But why do we need AI Agents if LLMs are already so capable?


LLMs vs. AI Agents: Key Differences

1. Large Language Models (LLMs) = The “Brain”

🧠 Strengths:
✔ Writing, translating, reasoning, answering questions
✔ Quick text generation & analysis

🚫 Limitations:
✖ No execution ability – Can’t perform multi-step tasks
✖ No memory – Starts fresh with each prompt
✖ No tool integration – Can’t browse the web, edit files, or run code

📌 Example:

  • Ask ChatGPT to “write a market report,” and it will suggest sections but won’t gather data, analyze trends, or generate charts automatically.

2. AI Agents = The “Brain + Hands + Memory”

🤖 Superpowers:
✔ End-to-end task execution – Breaks down complex workflows
✔ Memory & context awareness – Remembers past interactions
✔ Tool integration – Can browse, code, edit files, and more

📌 Example:

  • Ask an AI Agent to “create a market report,” and it will:
    • Research industry data
    • Analyze trends
    • Generate charts
    • Format into a polished document

4 Ways AI Agents Outperform LLMs

1. Full Workflow Automation

🔹 LLM: Gives advice but can’t execute.
🔹 AI Agent: Handles everything from start to finish.

📌 Example:

  • Prompt: *”Make a 2-minute video about Journey to the West from Red Boy’s perspective.”*
  • AI Agent’s Workflow:
    • Researches Red Boy’s story
    • Writes the script
    • Generates visuals & subtitles
    • Adds voiceover & music
    • Renders the final video

2. External Tool Integration

🔹 LLM: Text-only responses.
🔹 AI Agent: Can browse, code, edit files, and use software.

📌 Example:

  • AI Agent can:
    • Scrape real-time flight prices
    • Edit a spreadsheet
    • Run Python scripts

3. Memory & Continuous Learning

🔹 LLM: Forgets past conversations.
🔹 AI Agent: Remembers context and improves over time.

📌 Example:

  • If you ask an AI Agent to plan a trip, it remembers your preferences for future trips.

4. Real Digital Workforce

🔹 LLM: A consultant (gives advice).
🔹 AI Agent: A digital employee (executes tasks).

📌 Example:

  • LLM: “Here’s how to create a business plan.”
  • AI Agent: “I’ve created your business plan with financial projections. Here’s the PDF.”

How to Make Money with AI Agents

🎥 Use Case: Automated Storytelling Videos
With NanoAI’s Video Agent, you can create viral “first-person POV” videos in minutes.

📌 Workflow:

  1. Prompt: “Tell Journey to the West from Red Boy’s perspective.”
  2. AI Agent:
    • Researches the story
    • Writes the script
    • Generates visuals & voiceovers
    • Edits the final video
  3. Result: A professional video ready to post!

💰 Why This Matters:

  • Before: Making such a video required multiple tools (scripting, AI art, editing, voiceovers) and took days.
  • Now: AI Agents automate everything—no filming, editing, or voice acting needed.

How You Can Profit from AI Agents

🚀 Opportunities:
✔ Content Creation – Auto-generate videos, articles, social media posts
✔ E-commerce – AI-powered product research & marketing
✔ Consulting – Automate reports, presentations, and data analysis

💡 No Coding Required!
You don’t need to be a tech expert—just describe what you want, and the AI Agent handles the rest.


The Future: AI Agents + LLMs = Ultimate Productivity

  • LLMs (like ChatGPT) = The Brain (ideas, advice)
  • AI Agents = The Body (execution, automation)

🔥 The Choice is Yours:
