LongWriter is a research project from Tsinghua's THUDM group providing fine-tuned LLMs (based on GLM-4-9B and Llama-3.1-8B) plus training and inference code that enable generating 10,000+ word outputs from long-context models. It includes the LongWriter-6k dataset, the AgentWrite planning method, and LongWriter-Zero, an RL-trained variant.

Use cases

• generate 10000-word documents with an llm
• write long-form reports or travel guides in one shot
• fine-tune a model to produce very long coherent outputs
• deploy a chatbot that writes ultra-long text fast with vllm
• train an llm for long-text generation with reinforcement learning
• evaluate models on long-form writing benchmarks

When to choose

• you need single-pass generation of very long documents (10k+ words)
• you want to fine-tune or reproduce long-output LLM research
• you need open-weight 8-9B models specialized for long-form writing

When to avoid

• you only need short or medium-length responses
• you want a hosted API rather than self-hosting open models
• you lack GPU resources for 9B-32B model inference or training
