We used OpenLIT to make an AI agent cheaper and safer, then shipped the walkthrough

说明与用途

使用 OpenLIT 降低 AI 代理成本：从每次运行 $0.0052 降至 $0.0002，节省 26 倍，通过消除冗余工具调用并切换到更便宜的模型实现。

问题

High-cost, redundant tool calls in an AI support-desk agent leading to inefficiency and safety concerns.

结果

Reduced per-run cost from $0.0052 to $0.0002 (26× cheaper) by eliminating redundant tool calls and switching to a cheaper model, while improving safety through better loop logic.

工作流

• Scan the repo for issues
• Fix high-severity problems (missing docstrings, insecure paths)
• Run the agent and capture the trace with OpenLIT
• Analyze the trace to identify redundant tool calls
• Tighten the loop logic
• Switch to a cheaper model (gpt-4o-mini)
• Re-run and verify cost reduction
• Ship the improved agent

证据

First run: repeat lookup_ticket / create_ticket calls, spend $0.0052.

Second run, after tightening the loop and switching to gpt-4o-mini: $0.0002, one lookup, one create.
