What are AI Agents?

AI Agent

In a recent interview, Sam Altman (CEO of OpenAI) outlined five levels of AI development:

  • Chatbots: Basic AI models designed for simple conversations.
  • Reasoners: AIs capable of complex reasoning, like OpenAI's new o1 models.
  • Agents: AIs that autonomously make decisions and complete tasks.
  • Innovators: AIs driving scientific breakthroughs and discoveries.
  • Organisations: Advanced AI systems capable of running entire operations and making strategic decisions.

We are now approaching level 3—AI agents. So, what exactly are they?

What are AI Agents?

An AI agent is an advanced software designed to perform tasks autonomously. Unlike traditional software, which follows predefined rules, AI agents make decisions based on their environment and data inputs. They use sophisticated models like GPT (OpenAI), Claude (Anthropic), or Gemini (Google) to process information and determine optimal actions.

How AI Agents Differ from Traditional Software

Consider AI agents as intelligent project managers. Instead of giving them specific instructions (e.g., "email Jack to confirm his availability for a meeting"), you provide a broader objective (e.g., "schedule a meeting with Jack next month when our schedules align"). The AI agent will handle the rest—checking calendars, finding suitable times, and sending invites. This shift allows AI agents to focus on achieving outcomes rather than just executing tasks.

AI Agents vs Large Language Models (LLMs)

While AI agents use language models like GPT to understand and generate language, they operate at a higher level. Traditional LLMs are trained on historical data and lack real-time awareness. For instance, an LLM wouldn’t know about recent events unless explicitly updated. Some LLMs can perform web searches, but this is often an add-on rather than an inherent capability. AI agents, on the other hand, can interact with the world in real time, making decisions based on current data.

How AI Agents Work

AI agents perform multiple functions that go beyond standard AI capabilities:

  • Planning: They define a goal and break it down into smaller tasks, similar to how a human would.
  • Interacting with Tools: AI agents can use tools, browse the web, or access APIs to gather real-time data.
  • Memory and Knowledge: They can store and retrieve information, improving their ability to deliver relevant and up-to-date responses.
  • Executing Actions: AI agents can complete tasks like drafting reports, managing software, or coordinating with other AI agents for complex tasks.

The Future of AI Agents

Mark Zuckerberg (CEO of Meta) recently predicted that AI agents will eventually outnumber people. He envisions a future where every business, regardless of size, will have AI agents handling customer support, sales, and other critical functions.

Conclusion

AI agents represent a significant leap forward in AI capabilities. They plan, utilise real-time knowledge, and execute tasks autonomously, making them a valuable asset for businesses looking to innovate and streamline operations. As AI agents continue to evolve, they will undoubtedly drive automation across industries, positioning them as a critical tool for the future of business.
