LongWriter is a long text generation model developed by a team from Tsinghua University. Based on large-scale language models (LLMs), it can generate text contents exceeding 10,000 words. This model is particularly suitable for scenarios that require the generation of long, coherent texts, such as writing assistance and content creation. LongWriter has improved the quality and consistency of the generated text through fine-tuning and optimization while maintaining the model's efficiency and scalability.
