Context Window: What AI Can Actually See

Most people think AI remembers the conversation. It doesn't. What actually matters is something called the context window - the amount of information the model can see at one time. In this note, we break down what the context window really is. It's not the full chat. Not everything you ever wrote. Just a limited slice of text that is currently visible. The model can only think about what it can see. At any moment, the model receives a fixed block of context - your message, some recent messages, some instructions. That block is its entire world. Understanding this helps you work with AI more effectively. Reasoning only happens over what is visible. The model does not reason over the past - it reasons over the current context. ▶️ Full playlist: https://www.youtube.com/playlist?list=PL3pL28ov_GlKZ8fgcP04yi_nBuBc_i65C 📦 Join us in Telegram: https://t.me/unreasonableai Start tagging your content to indicate this is generated by Human (or not?).
