Official Microsoft Foundry / Azure OpenAI notice

Azure lifecycle stage: Deprecated. Version 1. Replacement spelled 'TimegGPT-2.1' on the page (as published).

How to migrate off TimeGEN-1

  1. Find every place that references it:
    grep -rn --exclude-dir={node_modules,.git,dist} "TimeGEN-1" .
  2. Replace the model ID:
    - model: "TimeGEN-1"
    + model: "TimeGPT-1"
  3. Re-run your evals or a sample of real prompts — output style, token usage and pricing can change between models.
  4. Check config outside code too: environment variables, feature flags, prompt-management tools, and fine-tuned model references.
  5. Deploy before August 31, 2026, and add the CI scanner so it cannot come back.
