Wen Xiaobai 5 Pro - YuanShi Technology's New-Generation Long-Content Generation Engine

What Is Wen Xiaobai 5 Pro?

Wen Xiaobai 5 Pro is YuanShi Technology's new-generation long-content generation engine, built on the self-developed YuanShi large model and the full DeepSeek-R1 671B version. It focuses on three core capabilities: long, stable, and verifiable. Through source traceability from a materials library, a project memory mechanism, and long-document structure preservation technology, Wen Xiaobai 5 Pro supports the generation and consistency maintenance of professional documents at the ten-thousand-character level, covering complex scenarios such as cross-border operations plans, game worldview design, and in-depth industry research reports. Its underlying technology won the ACL 2025 Outstanding Paper Award.

Main Features of Wen Xiaobai 5 Pro

• Materials Library Traceability: Supports uploading more than fifty materials. Every figure and judgment generated by the AI can be annotated with its source file, precisely tracing back to the original source.
• Project Memory Mechanism: Character profiles, faction stances, rule settings, and other elements remain continuously in effect as underlying constraints. Even when writing to the twentieth thousandth character, it can still remember the settings established in the first chapter.
• Long-Document Structure Preservation: Constrains the entire document through a project-level argumentation framework, ensuring that the overall structure does not fall apart, the depth of analysis remains balanced, and the reasoning logic stays consistent from beginning to end.
• DeepResearch In-Depth Research Reports: Supports multi-round research, analysis, and long-report writing, automatically completing material retrieval, reading comprehension, content writing, and visual webpage generation.
• File Sandbox Collaboration: Completes long-document creation in an independent canvas, supporting image embedding, version iteration, and cross-referencing between multiple modules.

Technical Principles of Wen Xiaobai 5 Pro

• Attributed Grounding Data Synthesis: Based on the ACL 2025 Outstanding Paper Award-winning paper, it trains the model by synthesizing millions of complex instruction data entries with source annotations, so that generated content is automatically linked to original sources.
• Agent Architecture for Long-Horizon Planning: Adopts a multi-round agent workflow of task decomposition → reasoning planning → material retrieval → reading comprehension → content writing → visualization generation, replacing single-turn dialogue generation.
• Project-Level Context Constraints: Stores worldview settings, argumentation frameworks, and preset analysis depth through an external memory module, continuously injecting constraints during generation to prevent logical drift and setting conflicts in long texts.
• Hierarchical Memory and Sparse Attention: Combines a MoE architecture with a dynamic sparse attention mechanism to reduce the KV Cache memory usage of long-text inference and achieve efficient processing of million-level token contexts.

How to Use Wen Xiaobai 5 Pro

• Visit the Official Website: Visit theWen Xiaobai App、web version, register, and log in to your account.
• Create a Project: Click New Project on the homepage, select the "Wen Xiaobai 5 Pro" mode, and enter the project topic and goal description.
• Upload Materials: Drag relevant reference documents (PDF, Word, Excel, PPT, etc.) into the materials library, and the system will automatically archive and categorize them.
• Set Constraints: Enter worldview settings, argumentation frameworks, or analysis depth requirements in the project configuration as underlying constraints.
• Publish the Task: Enter the specific writing requirements in the dialog box. The AI will automatically decompose the task, retrieve materials, generate content, and annotate sources.
• Iterative Review and Proofreading: Check the source citations section by section, modify the constraints, and let the AI continue generating or adjusting until the full text is complete.
• Export and Delivery: Export the final document in PDF or DOCX format, retaining both the citation sources in the knowledge base and the iteration versions.

Core Advantages of Wen Xiaobai 5 Pro

• Verifiable: Every fact can be clicked to trace back to the original file, completely resolving the trust crisis caused by AI hallucinations.
• Stable: The project memory mechanism ensures that in long texts, settings do not conflict, logic is self-consistent, and characters do not go OOC.
• Long: Supports coherent generation of 15,000 to over 20,000 words without repeatedly clicking "Continue Generating" to manually stitch content together.
• Structured Delivery: The output is a professional document with a table of contents, charts, and cross-references.
• Academic Endorsement: The underlying technology received the ACL 2025 Outstanding Paper Award, and the citation traceability capability is supported by the paper.

Application Scenarios of Wen Xiaobai 5 Pro

• Cross-border Operations Plans: Complete operations documents covering multiple platforms and time zones, with consistent data standards, which can be directly split into execution briefs for each country.
• Game Worldbuilding Design: Faction settings, character profiles, and combat rules for TCG/RPG remain consistent across tens of thousands of words, preventing setting contradictions.
• In-depth Industry Research Reports: Generates investment research reports with valuation models and risk matrices based on hundreds of materials, with every figure traceable.
• Official Documents and Policy Writing: Long official documents maintain standardized formatting and progressive logic, and cited policy documents can be precisely located by clause.
• Novel and Script Writing: In long novels, character personalities, timelines, and foreshadowing payoffs remain coherent throughout the entire text.
