The Context Window is an independent educational platform created by Abhishek Bisht, an Applied AI Research Engineer. It turns the concepts he studies through research papers, videos, blogs, and other sources into clear, first-principles explanations supported by code and interactive demonstrations. Rather than presenting itself as a formal course or textbook, the site serves as a growing collection of learning resources and a record of the author’s understanding, with references included where possible.

Its content spans neural networks, transformers, language models, reinforcement learning, reasoning systems, search, and production Python. Visitors can explore structured tutorial series, architecture walkthroughs, a six-month AI researcher preparation course, interview questions, a searchable research-paper library, and an archive of earlier writing. The site also offers a browser-based Python sandbox and LlamaChess, an interactive chess-puzzle experience. Many tutorials combine theory, mathematics, code, and hands-on demos, covering topics from building neural networks from scratch to LLM inference and modern search systems. The author notes that content may contain mistakes and welcomes corrections, including suggestions about missing source attribution.
