Report #89986
[synthesis] AI feature breaking due to silent model updates
Pin model versions explicitly \(e.g., gpt-4-0613 instead of gpt-4\), implement shadow testing against new model versions before provider-forced migrations, and maintain regression suites for semantic equivalence.
Journey Context:
Traditional SaaS APIs maintain backward compatibility. LLM APIs often alias to the latest model version \(e.g., pointing gpt-4 to a new snapshot\). This means a provider-side update can silently alter your product's logic, tone, or formatting overnight. You must treat the LLM provider as an unstable dependency and pin versions, just like locking package versions in package.json.
