Deep Blue Trade-in Subsidy refers to a subsidy policy provided by the government in mainland China to encourage consumers to purchase deep learning models (such as Amazon Echo, Google Home, etc.).

The policy stipulates that consumers can receive a certain percentage of subsidies when purchasing designated products, and the subsidy amount is issued in the form of shopping vouchers.

Through this policy, the government hopes to stimulate consumer demand and promote the development and popularization of deep learning models.
