LLM prompts are code: Pin model versions to avoid silent breaks

By PulseAugur Editorial · [1 sources] ·

Developers building on large language models must treat model IDs as versioned dependencies, akin to software libraries, to avoid unexpected behavior changes. The author, Serguey Asael Shinder, advises explicitly pinning model versions in configuration rather than using 'latest' identifiers. This practice is crucial for debugging, as it allows developers to determine if output discrepancies stem from model updates or user input changes. Shinder also recommends establishing a suite of saved test cases to run regularly, especially when prompts or model versions are updated, to catch regressions and prepare for eventual model deprecation.
