Keep Health Probes Off the Model on a Free Host
A free host probes and restarts. The health route has to answer from local memory, with no model call and no disk state. That split is what lets a solo founder ship one route today and keep the bill at zero. An AI draft often does the opposite. It puts a "model is reachable" check inside /health , adds a retry, and stores the last success in a global. The chat result looks careful. On a free…
To ensure a free host remains unburdened by health probes, the system enforces a strict policy. The health route must retrieve its data from local memory without invoking the model or accessing disk state. This separation allows a solo founder to launch a service and maintain zero operational costs. Conversely, an AI model often places health checks within the /health path, includes retry mechanisms, and retains the last successful response in a global variable.
On a free server, these probes execute far more frequently than any user requests, and a restart erases the global variable, causing the next probe to fail or attempt a connection again. The key distinction lies in the model's quality and the host's constraints, which represent separate issues. While a more precise draft can still incorporate a network call in the probe path, the host will not accommodate this without compromising its integrity. The workflow outlined below prevents such discrepancies from reaching the host.
