Ishigaki-IDS-8B: Specialized IDS Generation for Construction
Ishigaki-IDS-8B is an 8 billion parameter large language model developed by ONESTRUCTION Inc., specifically designed for generating Information Delivery Specifications (IDS) within the BIM construction domain. This model was developed as part of the GENIAC (Generative AI Accelerator Challenge) Project to strengthen Japan's generative AI capabilities. It is fine-tuned from the Qwen3 base model, chosen for its strong general language capabilities and broad adoption.
Key Capabilities
- Automated IDS Generation: Generates IDS XML from either CSV inputs or natural language instructions.
- IFC and IDS Compliance: Ensures generated IDS conforms to buildingSMART's IFC and IDS specifications.
- Domain Specialization: Optimized for construction domains including Architectural, Structural, and Equipment.
- Multilingual Support: Supports both Japanese and English for input and output.
- Supported Versions: Handles IDS version 1.0.0 and IFC versions IFC2X3, IFC4, and IFC4X3_ADD2.
Good For
- Streamlining IDS Authoring: Ideal for users, even those without deep IDS or IFC knowledge, to easily create compliant IDS documents.
- Automating BIM Data Checks: Generating specifications for checking properties of entities like doors (e.g., fire resistance, model numbers).
- Specialized Construction Tasks: Performing tasks where general foundation models typically underperform due to the highly specialized nature of IDS.
While capable of general text generation, its primary purpose and optimization are for IDS generation, making it highly effective for its intended specialized use case.
