OpenAI announced a 50% discount on GPT usage during off-peak hours, aiming to encourage users to utilize AI resources more effectively and reduce costs. With the introduction of this new discount policy, OpenAI's Batch API is also officially launched, providing users with a new way to process batch queries. Batch API allows users to upload files containing a large number of query requests to AI models, such as data classification or image annotation tasks. These tasks do not require immediate processing, so they can be performed during periods when computing resources are underutilized, effectively improving resource utilization. Users only need to upload the request files and will receive the processing results within 24 hours, greatly enhancing work efficiency. It is worth mentioning that Batch API not only provides a more flexible way of task processing but also brings cost benefits to users. By using this API, users can enjoy efficient asynchronous task processing while receiving a 50% discount on API prices. This is undoubtedly a great advantage for users who need to process large amounts of data or perform frequent queries. The discount policy and Batch API introduced by OpenAI not only reflect the company's emphasis on optimizing user experience and reducing costs but also demonstrate its technical strength and innovation spirit in the field of artificial intelligence. By properly utilizing computing resources, OpenAI has successfully achieved the goal of ensuring service quality while reducing the economic burden on users.
