[counterintuitive] more context window better performance

Optimize context for relevance and signal-to-noise ratio; blindly stuffing the context window degrades accuracy due to lost-in-the-middle effects and attention dilution.

Journey Context:
Developers maximize token usage assuming more information strictly equals better answers. Research shows LLMs struggle to retrieve information from the middle of long contexts. Irrelevant context acts as noise that degrades reasoning capabilities. A highly curated, concise context window consistently outperforms a massive dump of marginally relevant documents.
