LongWriter
by Tsinghua University and Zhipu AILongWriter is a state-of-the-art long text generation model developed by Tsinghua University in collaboration with Zhipu AI. It is designed to break the limitations of existing large language models by generating coherent texts that exceed 10,000 words. The model leverages the "LongWriter-6k" dataset and employs Direct Preference Optimization (DPO) technology to enhance output quality and adherence to length constraints. LongWriter is open-source, making it accessible for both academic research and practical applications.
What is LongWriter?
LongWriter is a cutting-edge long text generation model developed by Tsinghua University in collaboration with Zhipu AI. It is specifically designed to generate coherent texts exceeding 10,000 words, addressing the limitations of existing large language models in handling long-context outputs.
Main Features of LongWriter
- Ultra-Long Text Generation: Capable of generating coherent texts over 10,000 words.
- Dataset Construction: Utilizes the "LongWriter-6k" dataset for training, which includes writing samples ranging from 2,000 to 32,000 words.
- AgentWrite Method: Employs a divide-and-conquer strategy to enhance long-text generation capabilities.
- Direct Preference Optimization (DPO): Improves output quality and adherence to length constraints.
Technical Principles of LongWriter
- Long Context Processing: Based on long-context large language models with increased memory capacity.
- Output Length Analysis: Identifies limitations in model output length due to supervised fine-tuning (SFT) dataset characteristics.
- Supervised Fine-Tuning (SFT): Uses the "LongWriter-6k" dataset to train the model in generating longer texts.
