Benchmarking six context-optimization strategies (RAG, summarization, LLMLingua and hybrids) across LongBench, evaluating Llama-3.1-8B and Gemini-2.5-Pro on quality, token efficiency, latency and cost. Training an adaptive XGBoost and MLP selector to route each query to its optimal strategy over fixed baselines.
