Before you switch
- Run your own evaluation: price differences are certain, quality differences depend on your task.
- Prompt caching and the Batch API change the totals a lot; model them in the prompt caching calculator and the batch API savings calculator.
- Check the API differences for the newer model in Anthropic's migration guides before changing a production setting.
