Which of the following tasks can LLMs perform?

Large language models (LLMs) are capable of performing a variety of language-based tasks, leveraging their training on vast amounts of text data. One of these tasks is proofreading text. LLMs can analyze written content to identify grammar, punctuation, and spelling errors, as well as suggest improvements to enhance clarity and coherence. This capability is a result of their understanding of language rules and patterns acquired during training.

In the context of the other options, while translating text and summarizing articles are also well within the capabilities of LLMs, earning a university degree is not a task that can be performed by LLMs as it requires formal education and specific human attributes like attending classes and engaging in academic experiences. Therefore, dancing around the specific capabilities of LLMs, proofreading stands out as a direct task they can execute effectively.
