[counterintuitive] more context always better LLM

Aggressively filter and re-rank retrieved documents to include only the most relevant chunks. Avoid stuffing the context window with tangential information.

Journey Context:
Developers stuff prompts with as much text as possible, assuming more context gives the model a better chance of finding the right answer. LLMs suffer from the 'Lost in the Middle' phenomenon where they ignore information in the center of long contexts. More context increases inference time, cost, and latency, while adding irrelevant context degrades reasoning by acting as a distraction. A smaller, highly curated context window consistently outperforms a massive, noisy one.
