Any excellent Use Case example of Batch API?

Batch API was introduced in April this year . Can someone explain some amazing use cases of batch API by software developers in an organization ?

Pretty much anything for language model that is not a chatbot nor would require a chain of API calls, you can get a 50% discount on, if you don’t need it until tomorrow.

Embeddings on a large knowledgebase. Classifing a large set of data like reviews. Proofreading all your blog posts. Anything that is data in, data out, processed by AI, you can envision how a bit of delay is worth the savings, along with the convenience of getting a results file for your single uploaded batch job file.

Any example of including Batch API in applications built by developers for use by users.
