Agents fail commercially before they fail technically. Cost control means: routing cheap steps to small models, capping steps per run, caching stable context, trimming tool outputs before they re-enter the prompt, and tracking cost-per-completed-task rather than cost-per-token. Agent cost control is the practice of budgeting tokens, steps and model tiers per task so autonomous systems stay economically viable at scale.

Cost control means: routing cheap steps to small models, capping steps per run, caching stable context, trimming tool outputs before they re-enter the prompt, and tracking cost-per-completed-task rather than cost-per-token. In practice: Routing classification to a small model and reserving the frontier model for final synthesis cut a research agent from $0.42 to $0.07 per report.

  • Token Budgeting

    Token budgeting is the strategic allocation and management of token usage within large language model (LLM) operations to control costs and optimize performance.

  • Agent Architecture

    Agent architecture is the structural blueprint of an AI agent: the model, the planning loop, the tools, the memory layer and the guardrails that decide how it acts.

  • Multi-Agent System

    A multi-agent system splits a job across several specialised AI agents that coordinate through a shared plan, message bus or orchestrator.

  • Agent Handoff

    Agent handoff is the controlled transfer of a task — with its context — from one agent to another agent or to a human.

  • Single Agent vs Multi-Agent System

    One well-equipped agent beats a crowd for most jobs; multi-agent wins on genuinely separable, parallel work.

  • AI Agent vs Trading Bot

    A trading bot executes fixed rules deterministically; an AI agent interprets context and decides which steps to take — powerful for research, risky for execution.
