What is agentic AI?
Agentic AI refers to artificial intelligence systems capable of planning, deciding and acting autonomously to achieve a specific goal. Unlike a classic chatbot that answers a question and waits for the next one, an AI agent can chain multiple actions across different tools without constant human intervention.
The difference with traditional AI
To understand clearly, here's a concrete example:
| Scenario | Classic chatbot | AI Agent |
|---|---|---|
| "Organize my team meeting" | Gives you tips on how to organize a meeting | Checks calendars, finds a slot, sends invitations, prepares the agenda |
| "Reply to my non-urgent emails" | Suggests reply templates | Sorts emails, drafts appropriate responses, sends them after validation |
| "Find me qualified leads" | Explains how to qualify a lead | Searches for prospects, verifies profiles, enriches data, adds them to CRM |
The difference is major: an AI agent doesn't just give you information, it executes actions in the real (or digital) world.
How does an AI agent work?
An AI agent relies on a specific architecture called the PRA loop: Perception - Reasoning - Action.
The Perception-Reasoning-Action loop
- Perception: The agent collects information (data, events, context)
- Reasoning: It analyzes the situation and plans the necessary steps to achieve the goal
- Action: It executes the planned actions (API calls, file manipulation, message sending...)
This loop repeats until the goal is achieved or human intervention is needed.
Key components of an AI agent
To work effectively, an AI agent combines several technologies:
- An LLM (Large Language Model): The brain that understands instructions and reasons (GPT-5.2, Claude 4.5, Gemini 3...)
- Memory: Storage of context and past actions to maintain coherence
- Tools: Connections to APIs, SaaS services, databases...
- A planning system: Breaking down goals into actionable sub-tasks
- A feedback loop: Verification of results and adjustment if necessary

Real-world use cases for agentic AI
January 2026 analyses identify several areas where agentic AI already excels:
Automated customer service
AI agents can now:
- Understand a customer ticket and consult the knowledge base
- Check history in the CRM
- Apply refund policy if applicable
- Trigger the payment flow
- Notify the customer by email
All this without human intervention for standard cases. Complex files are automatically escalated.
Personal productivity ("desktop agent")
Imagine an assistant that manages:
- Your emails: Sorting, automatic simple replies, follow-ups
- Your calendar: Proposing slots, sending invitations, reminders
- Your tasks: Creating to-dos, updates in Notion/Asana, reminders
This is already possible with tools like Lindy or well-configured custom GPTs.
Sales and marketing
Sales teams use agents to:
- Generate qualified prospect lists
- Write personalized outreach emails
- Automatically track follow-ups
- Score leads based on engagement
- Launch and adjust marketing campaigns
Practical tip
Start by automating a simple, repetitive task (e.g., email sorting, weekly report creation). Once you master the concept, you can build more complex workflows.
Advantages and limitations of agentic AI
+ Advantages
- Massive time savings on repetitive and structured tasks
- 24/7 availability without fatigue or attention errors
- Scalability: an agent can handle volumes impossible for a human
- Consistency: same rules applied systematically
- Multi-tool integration: an agent can coordinate multiple applications
- Limitations
- Risk of cascading errors if the agent makes a bad decision
- Security: giving access to an agent carries risks
- Lack of judgment for unusual or sensitive situations
- Cost: enterprise solutions can be expensive
- Dependency: risk of losing skills if delegating too much
Warning
Never delegate to an AI agent tasks involving important financial decisions, sensitive data or critical communications without human verification. Agentic AI is a powerful assistant, not a replacement for your judgment.
The future of agentic AI
January 2026 trends outline a future where agentic AI will become mainstream:
Towards physical agents
Google DeepMind is already connecting Gemini to Boston Dynamics' Atlas humanoid robots. The goal: robots capable of manipulating unknown objects and accomplishing complex tasks in real environments.
Cisco is pushing the concept of "Physical AI LLMs": models connected to physical sensors to control robots, industrial lines and IoT.
Specialized agents by sector
We're seeing the emergence of Domain-Specific Language Models (DSLM) for finance, healthcare and legal. These smaller but specialized models meet confidentiality and regulatory constraints while remaining performant.
The security challenge
With agents acting autonomously, fraud detection and malicious behavior becomes crucial. AI-augmented anti-fraud systems are developing in parallel.
