How to migrate off o3-pro-2025-06-10
- Find every place that references it:
grep -rn --exclude-dir={node_modules,.git,dist} "o3-pro-2025-06-10" . - Replace the model ID:
- model: "o3-pro-2025-06-10" + model: "gpt-5.6-sol" - 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 December 11, 2026, and add the CI scanner so it cannot come back.
