New framework automates LLM prompt engineering using function calls

By PulseAugur Editorial · [9 sources] ·

Researchers have developed Reflective Prompt Tuning (RPT), a new framework that leverages LLM function calling to automate prompt engineering. RPT simulates human prompt engineers by having an LLM optimizer evaluate a target model, identify failure modes, and iteratively revise prompts based on diagnostic reports and accumulated memory. This approach shows particular effectiveness in multi-hop and mathematical reasoning tasks, improving performance and confidence calibration. AI

IMPACT Automates prompt design, potentially reducing manual effort and improving LLM performance on complex reasoning tasks.
