Cohere has introduced a new module within its LLM University called "Tool Use," which expands on retrieval-augmented generation (RAG) by allowing developers to automate tasks and workflows through the use of external systems, known as "function calling." This module includes chapters that cover the transition from RAG to tool use, the anatomy of tool use systems, and practical applications such as building AI assistants and multi-step workflows on platforms like LangChain, all backed by the Command R family of models. Alongside this module, Cohere has redesigned its LLM University for improved navigation and updated content, aiming to provide users with an engaging and comprehensive AI education experience. The company continues to focus on empowering individuals to master large language models for enterprise applications and remains committed to making AI education accessible and impactful.
