Long Context Window
The upper limit on the number of input tokens a language model can accept in a single inference pass. It has expanded from thousands of tokens to hundreds of thousands or even millions, though a difference exists between window capacity and effective utilization.

Long context is better suited to single, static large-document tasks and cannot replace the continuous retrieval needs for dynamically updated, massive enterprise data—this is the practical reason RAG is still necessary.
The article points out that traditional cross-shot consistency methods rely on first-and-last-frame conditioning, reference image injection, or long context windows, but once the interval grows longer, spatial references drift, and they cannot support precise revisiting of a specific historical moment.
Long context windows are regarded as infrastructure for Agent scenarios, rather than an optional performance metric.
'Context locking' corresponds technically to the 'Long Context Window' capability in the AI field.

Context window size does not equal effective context length; exceeding the effective attention range causes a forgetting drift phenomenon.
