Prompt Escalation for Lightweight Large Language Models: An Empirical Evaluation of Cost–Performance Trade-Offs
Prompt escalation can increase the resource requirements of lightweight large language models (LLMs) without improving predictive performance. We evaluated four instruction-tuned 2–4B models on Grade School Math 8K (GSM8K), CommonsenseQA (CSQA), Recognizing Textual Entailment (RTE), and the binary Stanford Sentiment Tr...
