Why This Model
THUDM’s LongWriter, a Llama 3.1 8B model fine-tuned on the LongWriter-6k dataset — 6,000 examples specifically designed for generating outputs exceeding 10,000 words in a single generation. Most language models hit a wall around 2,000 words regardless of context window size. LongWriter was trained to break through that wall. With vLLM, it produces 10,000+ words within a minute. 32K context window for ingesting long source material. Built for the use cases other models abandon: full research papers, comprehensive reports, complete documentation sets.
Default System Prompt
Minimal by design — the model's fine-tuning does the heavy lifting. Override with a custom system parameter if needed.
Write extended documents. Structured, thorough, well-organized. Produce complete, detailed output.
