In this comprehensive JavaScript tutorial, viewers learn how to use Mistral AI to build intelligent applications, ranging from simple chat completions to advanced use cases like Retrieval-Augmented Generation (RAG) and function calling. The course, created by Per Borgen from Scrimba in collaboration with Mistral AI, offers hands-on experience with Mistral’s open-source models, such as Mistral 7B and Mistral 8x7B, as well as their commercial models. The tutorial covers the basics of Mistral’s JavaScript SDK, creating embeddings, setting up a vector database with Superbase, and performing semantic searches. It also delves into building AI agents capable of function calling, enabling applications to perform actions based on user prompts. Towards the end, viewers learn how to run Mistral models locally using Ollama, facilitating local AI model inference. The course is interactive, with challenges and exercises to solidify understanding, making it suitable for developers looking to enhance their AI engineering skills.
