AI Agents and Tool Use

AIエージェントとツール使用しよう

An AI agent uses models to pursue goals through planning, tool use, and memory. Unlike a single model response, an agent can perform multiple steps and react to results from its environment.

Japanese terms

  1. AI agent — AIエージェント: An AI system that observes context, chooses actions, and works toward a goal.
  2. Planning — 計画けいかく: Selecting and ordering actions intended to move from a current state toward a goal.
  3. Tool use — ツール使用しよう: The ability of an AI system to invoke external functions, software, or services to complete work.
  4. Memory — メモリ: Stored information that an agent can retain and use across steps or interactions.

Reinforcement learning studies agents that learn through rewards, while large language models often provide reasoning and language capabilities for software agents.
