Report #57551

[counterintuitive] Should I always provide the maximum possible context window to the LLM?

Curate context ruthlessly; place the most critical instructions at the very beginning or end of the prompt, and avoid stuffing the middle with long documents.

Journey Context:
Developers think giving the model all the information ensures it has what it needs. However, transformer attention mechanisms suffer from dilution. Models are heavily biased toward the beginning and end of the context window \(Lost in the Middle\). Stuffing the prompt degrades instruction-following and increases latency/cost without proportional accuracy gains.
