When Anthropic deprecates an older Claude model, what typically happens to API calls using that model ID?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Deprecation means you get a grace period, then the old model ID stops working. Track Anthropic's announcements and test migration before the deadline.

Full Explanation
When Anthropic deprecates a model, they typically provide advance notice and a migration timeline. After the sunset date, API calls using the deprecated model ID may return errors or be redirected to a newer model (which may have different behavior). Developers should: monitor Anthropic's announcements, test their applications with the replacement model, and migrate before the deprecation deadline. Option A is wrong — deprecated models don't work forever. Option C is wrong — no 'free tier' exists for deprecated models. Option D is wrong — automatic silent upgrades would cause unexpected behavior changes and don't match Anthropic's practice.
