Free AI Servers Are a Trap Until You Meter Them

说明与用途

免费 AI 服务器需要手动计量令牌：创建 SQLite 日志，设定每日预算，并在超额时阻止请求。

问题

Free AI tiers give generous token quotas that can quickly deplete if not monitored, leading to unexpected costs or service interruptions.

结果

Implementing a token ledger and daily budget enforcement turns a free AI tier into a controlled experiment, preventing unexpected quota exhaustion and providing clear usage metrics.

工作流

• 1. Define a narrow, measurable question for the free tier.
• 2. Create a token ledger (SQLite) to record each request’s prompt and completion tokens.
• 3. Estimate token counts using a heuristic or provider usage data.
• 4. Check the daily total against a set DAILY_BUDGET before sending a request.
• 5. If the budget would be exceeded, raise an error and stop the request.
• 6. Otherwise, send the request to the OpenAI‑compatible endpoint and log the result.
• 7. Commit the ledger entry and return the response to the caller.

证据

Free infrastructure removes the price signal, so you have to rebuild that signal yourself.

The following client wrapper records every prompt, every completion, and a running daily total in a SQLite ledger.
