How to migrate off ai21.jamba-1-5-large-v1:0
- Find every place that references it:
grep -rn --exclude-dir={node_modules,.git,dist} "ai21.jamba-1-5-large-v1:0" . - 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.
- Deploy before November 26, 2026, and add the CI scanner so it cannot come back.
