How to migrate off gemini-2.5-pro
- Find every place that references it:
grep -rn --exclude-dir={node_modules,.git,dist} "gemini-2.5-pro" . - Replace the model ID:
- model: "gemini-2.5-pro" + model: "gemini-3.5-flash" - 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 October 20, 2026, and add the CI scanner so it cannot come back.
