Report #26330

[counterintuitive] If a model has a 128k context window, should I fill it with as much codebase context as possible to improve its answers?

Curate context aggressively. Use a map/reduce or repomap approach to send only signatures and relevant snippets, keeping total context under 20-30% of the window limit to avoid degraded instruction following.

Journey Context:
Models suffer from the 'Lost in the Middle' phenomenon. When instructions are buried in massive context, the model ignores them. Furthermore, long contexts increase latency and cost, while diluting the attention mechanism's focus on the actual task. High-signal, compressed context \(like just class definitions and docstrings\) yields better code generation than dumping entire files.
