What is last model in ipods product line?

As an AI language model, I do not have access to current or updated information as I only have training data until October 2021. However, the latest iPod model as of October 2021 is the iPod touch 7th generation, which was released in May 2019. The iPod touch 7th generation features an A10 Fusion chip, up to 256 GB of storage, a 4-inch Retina display, an 8-megapixel camera, and support for AR gaming and Group FaceTime. It also runs on iOS 12 and supports the latest iOS 14 updates. The iPod touch 7th generation comes in six different colors, including gold, space gray, silver, pink, blue, and red, and is compatible with the latest version of Apple Music and the App Store.
