LongWriter: A New AI Model for Generating Long-Form Text
Beijing, China – A new AI model called LongWriter, developed byTsinghua University and the Beijing-based AI company Zhipu AI, has been released, promising to revolutionize the way long-form text is generated.This groundbreaking model can produce coherent text exceeding 10,000 words, breaking the previous limitations of AI models in terms of output length.
LongWriter’s capabilities stem from a combination of innovative techniques and a carefully curated dataset. The researchers addressed the core issue of limited output length in existing AI models by creating the LongWriter-6k dataset, which comprises writing samples rangingfrom 2,000 to 32,000 words. This dataset provides the model with a rich source of long-form text data, enabling it to learn the nuances of generating extended content.
The development teamalso employed the AgentWrite method, a novel approach that leverages existing large language models (LLMs) to automatically construct super-long output data for supervised fine-tuning (SFT). This method adopts a divide and conquer strategy, effectively enhancing the model’s ability to generate long-form text.
Furthermore, LongWriter incorporates direct preference optimization (DPO) technology, which further refines the model’s output quality and its ability to adhere to length constraints specified in instructions. This ensures that the generated text not only meets the desired length but also maintains high standards of coherence and accuracy.
Technical PrinciplesBehind LongWriter
LongWriter is built upon a long-context LLM with significantly increased memory capacity, allowing it to process historical records exceeding 100,000 tokens. This enhanced memory capacity is crucial for handling the complexity of long-form text generation.
The researchers meticulously analyzed the maximum outputlength of existing models under different queries, discovering that the limitation primarily originated from the characteristics of the SFT datasets used in their training. By employing the LongWriter-6k dataset during SFT, LongWriter learns to generate longer text effectively.
