How to migrate off gpt-4o-mini-realtime-preview

Find every place that references it:

grep -rn --exclude-dir={node_modules,.git,dist} "gpt-4o-mini-realtime-preview" .

Replace the model ID:

- model: "gpt-4o-mini-realtime-preview"
+ model: "gpt-realtime-mini"

Re-run your evals or a sample of real prompts — output style, token usage and pricing can change between models.
Check config outside code too: environment variables, feature flags, prompt-management tools, and fine-tuned model references.
Deploy before May 7, 2026, and add the CI scanner so it cannot come back.
