I went through 14 reports of AI agents burning money

说明与用途

AI 代理因预算检查与实际调用之间的竞争导致经常超支。解决方案是在请求前预留最坏情况费用，并拒绝会导致超支的调用。

问题

AI agents often exceed budget due to race conditions between budget checks and actual API calls, leading to excessive spending.

结果

By pre‑reserving a worst‑case cost and refusing calls that would exceed the budget, the library eliminates the race condition that caused 14 documented failures, ensuring agents stay within budget.

工作流

• 1. Agent reads current budget for the requested model. 2. Library reserves a worst‑case amount for the anticipated call. 3. If reservation would exceed the ceiling, the call is refused. 4. If reservation succeeds, the call proceeds. 5. After the call, the library settles the actual cost and updates the budget.
• 6. Repeat for each subsequent request.

证据

Nothing re‑checks budget on the deployment that actually bills.

multiple agents can observe remaining budget and start model calls before the governor's next poll.
