GA

• Azure sets a retirement date for every GA model at launch (18-month policy); this is a scheduled date, not a deprecation announcement. Preview models may be force-upgraded.
• Azure identifies models by name + version; in code the string you see is usually a *deployment name* chosen by the user, so match on model name + version in deployment configs/IaC. Azure model names differ from OpenAI's (e.g. 'gpt-35-turbo').
