[counterintuitive] Can I replace RAG with a massive context window

Continue using RAG and chunking even with 1M\+ token context models. Only inject the specific relevant chunks to minimize cost, latency, and attention dilution.

Journey Context:
With models offering 1M-2M tokens, developers assume they can just dump entire codebases into the prompt. While technically possible, this causes massive latency, high cost \(input tokens\), and severe performance degradation due to attention dilution. The model struggles to find the needle in a massive haystack compared to a targeted RAG approach.
