JGOS-31B-Citizen
JGOS-31B-Citizen is a Korean, multimodal large language model specialized for administrative & public-sector AI services — civil-complaint response, public-document understanding, and government-domain question answering.
Overview
JGOS-31B-Citizen is built on VIDRAFT's Darwin V8 platform.
- Base + FFN transfer, breeding & evolution (Darwin V8). Starting from our in-house gemma4-31b base, the feed-forward network (FFN) blocks of multiple source models are extracted and grafted, then bred (merged) and evolved across multiple generations through the Darwin V8 pipeline to accumulate capability.
- Korean administrative-domain fine-tuning. The evolved model is further trained on Korean-specialized datasets to strengthen Korean comprehension, reasoning, and administrative/public-sector domain performance.
The set of grafted source models, the number of evolution generations, the breeding strategy, dataset composition, and training configuration are proprietary and not disclosed.
