Intro to Mistral AI
Scrimba's free course on building with Mistral AI, taught by Per Borgen across about 1.4 hours. It runs from simple chat completions up to RAG and function calling, all without a Pro subscription.
Quick answer
Intro to Mistral AI is Scrimba's free, intermediate course on building intelligent apps with the Mistral models: roughly 1.4 hours across 27 lessons, taught by Per Borgen. You start with simple chat completions and work up to more advanced patterns like RAG and function calling. Because it is free, it is one of the best low-risk ways on the catalog to learn how LLM app patterns actually work.

It is free and it covers real ground, which is a rare combination. The patterns you learn (chat completions, RAG, function calling) are the same ones you would meet in a paid LLM course, just demonstrated with Mistral. For anyone weighing up the AI track, this is a genuine, no-cost way to find out whether the material clicks.
The honest caveat is the level. It is labelled Intermediate and means it, assuming you can write JavaScript and call an API. It also moves through advanced patterns like RAG quickly, so it is a working introduction rather than a deep treatment of each one.
What you'll learn
The course climbs from the basics to the useful patterns. You begin with chat completions to get a model responding, then move into Retrieval-Augmented Generation to ground answers in your own data, and function calling so the model can trigger code. Mistral is the provider, but the techniques are general, which is the point: learn the shape of an LLM app once and reuse it anywhere.
Who it's for, and who should skip it
It fits developers who can already code and want a free, practical look at LLM app patterns before committing to the Pro AI track. It also suits curious people who learn best by building.
Skip it, for now, if you have never written JavaScript; the Intermediate pacing will bite. Start with Learn to Code with AI or Learn JavaScript, then come back.
Prerequisites
Working JavaScript and a basic grasp of calling an API. No prior AI experience needed. If your JavaScript is shaky, do Learn JavaScript first.
Where it fits
This is a free stop on the AI Engineer Path and a strong companion to the paid fundamentals. The patterns here preview what Intro to AI Engineering and Learn RAG cover in more depth, so it works well as a free taster before those.
Free or Pro
The course is free, start to finish, no subscription required. Scrimba Pro is a separate decision that unlocks the full AI Engineer Path, the challenges, and certificates. See current plans if you later want the path structure.
Strengths and limits
What it does well: it is free, it covers real LLM patterns including RAG and function calling, and Per Borgen teaches it clearly.
Where it is limited: the Intermediate pacing assumes working JavaScript, and it moves through the advanced patterns quickly, so it introduces rather than exhausts them.

Yes. The full course is free with no credit card or Pro subscription required. Pro only adds the career paths, certificates, and Discord.
Not as a first course. It is rated Intermediate and assumes working JavaScript. True beginners should start with Learn to Code with AI.

Yes. Mistral is the provider, but the patterns (chat completions, RAG, function calling) are general and reused across LLM providers.
