| Challenge: | Automatic prompt optimization (APO) is a powerful paradigm for improving LLM performance without manual prompt engineering. |
| Approach: | They propose a framework that decouples hypothesis generation from prompt rewriting . they propose VISTA framework that recovers accuracy to 87.57% on same defective seed . |
| Outcome: | The proposed framework outperforms baselines on GSM8K and AIME2025 on a defective seed. |
