It highlights that while free endpoints eliminate monetary invoices, they still incur operational costs such as increased retry times, capacity drift due to shared infrastructure, and accounting inaccuracies if token counts are unreliable. The author proposes a probe runner script, adaptable to OpenAI-style APIs, to test six specific output cases, ensuring the endpoint adheres to a defined contract and detecting deviations that could impact downstream features.

    Probe a Free Model Endpoint With a Six-Case Output-Policy Contract

    <p>A free model endpoint removes the invoice, but it does not remove the operational contract. The first thing to fail is rarely overall quality. It is a boundary case: a prompt that used to return JSON now returns prose, a refusal boundary shifts after an upstream update, or the…
