xAI recently notified API customers of its Grok models about the deprecation of eight models with only nine days' notice. While the announcement stated these models would cease functioning, xAI's documentation indicates that requests to retired slugs will silently redirect to the newer grok-4.3 model. This redirection, however, will be billed at grok-4.3's higher pricing and may alter the model's reasoning behavior without explicit notification, posing a risk of unexpected costs and application changes for developers.
