I’m looking at using DeepSeek through its API in an application, and I’m trying to understand how other developers deal with model updates. Even when an endpoint follows familiar conventions, a model alias or a change in response behavior can affect an existing integration.

Do you pin a specific model identifier, keep a fallback provider, or test outputs before adopting updates? I’d especially like to hear what has worked for teams managing API version changes without surprising users or disrupting production.
