- Use tools and APIs
- Learn from interactions
- Execute multi-step workflows
- Collaborate with other agents
- Make contextual decisions
It typically combines:
- Large Language Models (LLMs)
- Memory systems
- Planning engines
- Tool integrations
- Reasoning capabilities
- External APIs
- Workflow orchestration
Modern AI agents can behave like virtual developers, assistants, researchers, operators, or autonomous workers.
Why It Matter in 2026
The software development industry is moving toward autonomous workflows. Developers no longer want AI that only answers questions — they want systems that can complete tasks end-to-end.
Examples include:
- Generating and deploying code
