One of the model families Amazon put inside Bedrock on the day it opened, announced in March 2023 in three sizes named Jumbo, Grande and Large, and answering in Spanish, French, German, Portuguese, Italian and Dutch as well as English. AWS switched it off region by region rather than all at once: Oregon in October 2024, Virginia the following March. It died twice, five months apart.
