Agentic AI: AI ทำงานแทนมนุษย์ - คิด วางแผน ลงมือทำ เรียนรู้ด้วยตัวเอง

Agentic AI คือ AI ที่ทำงานอิสระแบบ "ตัวแทนดิจิทัล" รับเป้าหมาย → วางแผน → ดำเนินการ → ปรับปรุง 4 ขั้นตอนหลัก ไม่ต้องสั่งละเอียดทุก step

Agentic AI 4-Step Loop

1. PERCEIVE: รับข้อมูล (API/DB/Sensor)
2. REASON: วิเคราะห์+วางแผน (LLM+Tools)
3. ACT: ลงมือทำ (Email/DB/API calls)
4. LEARN: ปรับจาก feedback
→ Loop ต่อเนื่อง
