Agentic AI
Agentic AI refers to artificial intelligence systems that can autonomously plan, execute, and adapt complex sequences of actions to achieve specific goals without constant human intervention. These systems combine reasoning, tool usage, and iterative refinement to solve multi-step problems in dynamic environments.
Companies urgently need Agentic AI to automate complex workflows like customer support, data analysis pipelines, and software development processes, reducing operational costs and scaling capabilities. The shift from single-task AI models to autonomous agent systems represents the next frontier in AI productivity, with major players racing to deploy AI assistants that can handle end-to-end business processes.
