Zeeshan Patel*, Karim El-Refai*, Jonathan Pei*, Tianle Li *Equal contribution EMNLP Findings 2024 arXiv SWAG is a novel approach to storytelling with LLMs which reduces story writing to a search problem through a two-model feedback loop. SWAG can substantially outperform previous end-to-end story generation techniques when evaluated by GPT-4 and through human evaluation, and our SWAG pipeline using only open-source models surpasses GPT-3.5- Turbo. |
