`gpt-4-0314` deprecation: shutdown date & replacement

Shut down March 26, 2026

gpt-4.1 suggested for latency-sensitive tasks not requiring reasoning.

How to migrate off gpt-4-0314

Find every place that references it:

grep -rn --exclude-dir={node_modules,.git,dist} "gpt-4-0314" .

Replace the model ID:
```
- model: "gpt-4-0314"
+ model: "gpt-5"
```
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 March 26, 2026, and add the CI scanner so it cannot come back.
