[counterintuitive] Larger context windows eliminate the need for chunking and retrieval strategy

Still chunk and rank your data; place the most critical information at the very beginning or end of the prompt context, never in the middle.

Journey Context:
With 100k\+ context windows, developers often dump entire documents into the prompt, assuming the model will 'find' the answer. Research shows LLMs suffer from severe 'Lost in the Middle' degradation: they recall information at the start and end of the context highly accurately, but accuracy plummets for information in the middle. Brute-force context stuffing wastes tokens, increases latency, and actively hurts recall compared to a targeted RAG approach that places only relevant chunks at the prompt boundaries.
