When your model is retired, your agent needs a re-test.
Every date below is read from the vendor's own deprecation page; follow the source link to check. Dates differ by platform (for example, the same Claude model retires later on AWS Bedrock than on the Claude API).

What a retirement means for your agent
A replacement model is not the same model: prompts tuned to the old one can drift, and cost per task changes. Some platforms silently route old model names to the new one and bill at the new price. Before the date, run your own tasks on the replacement and on one cheaper option, and see which tasks change.
