Cohere is a platform that provides large language models (LLMs) for natural language generation (NLG) and understanding (NLU). Its purpose is to help users create and interact with natural language content using state-of-the-art LLMs. Cohere allows users to fine-tune, test, and deploy LLMs for various use cases, such as text generation, summarization, rewriting, extraction, search, clustering, and classification. Cohere is designed to be used by users who want to leverage the power of LLMs for their natural language needs.
