Context Windows Are Not Memory: A Student Builds an Open-Source LLM Memory Framework
Cohere_Labs · x · 2026-08-20
A new Cohere Labs community post by Vijay Kumar starts with a frustrating ChatGPT moment: a long session hit the context limit, forcing a restart that wiped the model's understanding of his project's file structure, bugs, and attempted fixes.
That pain led him to dig into how LLMs actually work — tokens, fixed context windows, autoregressive transformers — and eventually to build an open-source framework for deciding what an LLM should actually remember: selective memory management that compresses or discards stale context instead of just scaling the window.
