  "account": "Retries should not be implemented until the system understands what it has already accomplished. Both free model endpoints and free servers can fail at a crucial point: after the work may have executed but before the response is received. This article discusses a method developed by MonkeyCode for handling free model access and using a free server option. The workflow outlined is a client-side protective measure, not a guarantee from the provider. The issue with retries by default is that a free server worker can be reused in the middle of a request, and a free model endpoint can timeout during the generation process. A retry has the potential to duplicate a downstream write or produce a combination of JSON and non-JSON data. The key rule to remember is to maintain clear separation between the intention of the request, the raw response, and the accepted outcome. A retry is only safe when the accepted result is not present and there is no indication of a partial downstream effect. The idempotent request journal is a Python tool used to document each step of the process. It takes the prompt and request parameters, hashes them into a unique key, and logs events in a JSONL file. The journal ensures that only a complete JSON payload is accepted and recorded. The code provided demonstrates how to implement this journal, append events to it, retrieve the last event for a given key, and validate the raw data. Finally, a function called request_once is defined, which appends a 'SENT' event to the journal, attempts to execute the call, validates the returned data, saves the result temporarily, replaces the permanent result file with the new data, logs a 'COMPLETE' event, and returns the payload.",

Free model endpoints and free servers fail in the worst place: after the work may have run but before you receive the response. Disclosure: This article was prepared as part of MonkeyCode's product outreach. I rely on two operator-supplied availability claims only: MonkeyCode has free model access and a free server option.
