/ quick answer

Attack context size, model tier and step count in that order, measuring after each. A measurable cost-reduction pass for any agent already in production.

A measurable cost-reduction pass for any agent already in production. The problem it solves: Agent bills scale linearly with usage and kill the unit economics of the feature. Attack context size, model tier and step count in that order, measuring after each. It runs in 6 steps, starting with instrument cost-per-completed-task, not cost-per-call. This workflow node is part of the Onexial knowledge graph and links to related concepts, workflows and tools below.
Problem
Agent bills scale linearly with usage and kill the unit economics of the feature.
Solution
Attack context size, model tier and step count in that order, measuring after each.
Steps
  1. 01Instrument cost-per-completed-task, not cost-per-call.
  2. 02Trim context: strip raw tool output, summarise before re-injecting, cap history.
  3. 03Enable prompt caching for the stable system + knowledge prefix.
  4. 04Route by step: small model for classify/extract, frontier model for final synthesis.
  5. 05Cap steps and add early-exit conditions when the goal is already satisfied.
  6. 06Re-run the eval suite after each change — never trade accuracy blindly.

The vocabulary this page depends on.

  • Agent Cost Control

    Agent cost control is the practice of budgeting tokens, steps and model tiers per task so autonomous systems stay economically viable at scale.

  • Context Engineering

    Context engineering is the discipline of deciding exactly what information enters a model's context window, in what order and at what cost.

  • AI Evaluation

    AI evaluation is the measurement layer of an AI system: a fixed set of cases, a scoring method and a tracked pass rate you can regress against.

  • 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.

Comparisons & alternatives

Pick between the options.

  • 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.
