Cohere Examples

Welcome! This repository provides a collection of examples to help you build LLM-powered applications with the Cohere API. They contain step-by-step guides, with code examples and explanations, to help you understand and use the API effectively.

The examples are grouped into 3 categories:

1. Getting started: A Cohere 101 guide. Build your first Cohere application – an onboarding assistant for new hires.
2. LLM University: The code companion to the LLM University course containing a comprehensive list of modules.
3. Cookbook: Deep dive into various techniques in the following topics: RAG, Agents, Search & embeddings, Summarization, and Others
