Context windows explained: why bigger isn't the fix for confused agents
Initial_Side3681 · reddit · 2026-10-15
A author-published explainer on La Frontera IA breaks down what the context window really is and why it causes agent failures.
- The basics: the context window is everything the model can 'see' when responding
- What actually fills an agent's window: system prompts, conversation history, tool outputs, retrieved content
- How windows are measured (tokens vs effective capacity)
- Key argument: a bigger window isn't always the fix — the post walks through what happens as it fills up, with real data
