Who This Roadmap Is For

Beginner-level individuals with minimal prior knowledge who aspire to create production‑ready large‑language models.

What You'll Learn

Master the mathematical and statistical principles (linear algebra, calculus, probability, statistics, optimization) that underpin large‑scale language models.
Build, fine‑tune, and evaluate a transformer‑based language model with a solid quantitative foundation.
Deploy the model at scale in a production environment with robust monitoring, security, and ethical safeguards.
Apply best practices for bias mitigation and safe‑use in large language models.

Prerequisites

Basic programming skills (Python)
Introductory knowledge of mathematics (algebra, basic calculus, probability)
