An artificial intelligence (AI) agent refers to a system or program that is capable of autonomously performing tasks on behalf of a user or another system. It achieves this goal by designing its workflow and employing available tools.
Applications and devices equipped with AI can see and identify objects. They can understand and respond to human language. They can learn from new information and experience. But what is AI?
Developers build AI assistants on top of foundation models—for example, IBM Granite, Meta’s Llama models, or OpenAI’s models. Large language models (LLMs), which specialize in text-related tasks, represent a subset of foundation models.
