How to migrate off Meta-Llama-3.1-405B-Instruct

grep -rn --exclude-dir={node_modules,.git,dist} "Meta-Llama-3.1-405B-Instruct" .

Follow the provider’s migration notes in the official notice.
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.
