Report #86836

[counterintuitive] Should I always include as much context as possible in the prompt?

Curate context strictly to what is necessary, placing critical information at the very beginning or end of the prompt, because middle context is often ignored.

Journey Context:
Developers often dump entire documents or massive histories into prompts assuming 'more context = better decisions.' However, transformer attention mechanisms suffer from dilution. Performance degrades significantly when relevant information is buried in the middle of long contexts, sometimes causing the model to perform worse than if it had no context at all.
