Large Language Models (LLMs) offer new possibilities for automated content generation, but their application to worldbuilding faces three challenges: context explosion that grows linearly with the building process, the tension between creative diversity and content consistency, and the absence of automated quality assurance. This paper presents AutoWorldBuilder, a multi-agent collaborative system that addresses these challenges through five integrated components: a structured concept network with conflict detection; a DAG-based hybrid batch scheduler that groups tasks by semantic locality; a four-layer context compression mechanism achieving approximately 90% token reduction; an iterative review system with specialized Auditor agents that improves proposal pass rates from 42% to over 85%; and a skill-driven agent architecture supporting zero-code extension with differentiated temperature configuration. Two experiments across 20 diverse worldbuilding tasks, using GPT-OSS 120B and DeepSeek v3.2 as LLM backends, demonstrate a 95.0% success rate. The system generated 56-103 self-consistent concepts per world in 18-31 minutes with zero-conflict delivery. The architectural patterns validated here, including layer-as-budget compression, semantic-locality scheduling, and separation of generation and review, transfer to the broader class of knowledge-intensive, multi-agent LLM applications.", "url": "https://wpnews.pro/news/fictional-worldbuilding-multi-agent-llm-collaboration-with-hierarchical-context", "canonical_source": "https://arxiv.org/abs/2607.09403", "published_at": "2026-07-13 04:00:00+00:00", "updated_at": "2026-07-13 04:09:01.623591+00:00", "lang": "en", "topics": ["large-language-models", "generative-ai", "ai-agents", "natural-language-processing", "ai-research"], "entities": ["AutoWorldBuilder", "GPT-OSS 120B", "DeepSeek v3.2"], "alternates": {"html": "https://wpnews.pro/news/fictional-worldbuilding-multi-agent-llm-collaboration-with-hierarchical-context", "markdown": "https://wpnews.pro/news/fictional-worldbuilding-multi-agent-llm-collaboration-with-hierarchical-context.md", "text": "https://wpnews.pro/news/fictional-worldbuilding-multi-agent-llm-collaboration-with-hierarchical-context.txt", "jsonld": "https://wpnews.pro/news/fictional-worldbuilding-multi-agent-llm-collaboration-with-hierarchical-context.jsonld"}}
