Enhanced AI Models Now Capable of Generating Lengthy Texts
Researchers have made a groundbreaking discovery in the field of AI language models that enables them to produce texts exceeding 10,000 words, a remarkable advancement from the previous limit of 2,000 words. This progress is attributed to the innovative method known as "AgentWrite," which effectively breaks down extensive writing tasks into manageable subtasks, empowering the models to generate coherent outputs of up to 20,000 words.
The limitation on output length was predominantly due to the composition of the training data, specifically the absence of extensive examples in supervised fine-tuning datasets. To counter this limitation, the researchers devised the "LongWriter-6k" dataset, comprising 6,000 examples with varying output lengths spanning from 2,000 to 32,000 words. The utilization of this dataset has resulted in a successful amplification of the output length of existing models without compromising quality.
Moreover, the team introduced "LongBench-Write," a benchmark designed to assess the ultra-long generation capabilities of AI models. A 9-billion-parameter model, enhanced with Direct Preference Optimization (DPO), demonstrated exceptional performance on this benchmark, surpassing larger proprietary models. The code and model for LongWriter are now accessible on GitHub, signaling a significant leap in AI text generation capabilities.
