A.X-3.1-Light SFT Source Screen 71894 (General, Mathematics, Korean Culture 3K)

이 모델은 skt/A.X-3.1-Light를 기반으로 AI Hub 71894 지식·지능 데이터의 일반지식, 수학, 한국문화·역사 영역만 사용해 한국어 질의응답 및 지시 수행을 LoRA 방식으로 1 epoch 지도학습한 모델입니다. 학습 후 LoRA adapter를 base model에 병합한 BF16 standalone 전체 가중치 모델이므로 추론 시 별도의 adapter가 필요하지 않습니다. 다양한 길이의 설명형 답변을 포함한 연구용 모델이며, 생성 결과가 항상 정확하거나 완전하지 않을 수 있습니다.

Model details

Model name: A.X-3.1-Light SFT Source Screen 71894 (General, Mathematics, Korean Culture 3K)
Base model: skt/A.X-3.1-Light
Base model revision: 9b41bb2406472634d8812c0b8931fa40fa9a6c3a
Fine-tuning: LoRA supervised fine-tuning, merged into base weights
Weight format: BF16 safetensors
Architecture: unchanged Llama causal language model architecture
Chat template: bundled A.X tokenizer chat template
Custom model code: none; standard Transformers/vLLM loading is intended

Training data

Training used only AI Hub dataset 71894, 지식·지능 데이터. The training split contains 3,000 selected examples and the separate development split contains 300 examples. No v0.21 mixture, other AI Hub dataset, public benchmark question, benchmark answer, or evaluation artifact was used as SFT data or included in this repository.

Domain	Training examples
General knowledge	1,000
Mathematics	1,000
Korean culture and history	1,000
Total	3,000

The output contract is answer-first: the key answer is presented first and a short rationale may follow. The data were serialized with a 2,048-token maximum and the training summary reports zero runtime target truncation. The applicable AI Hub terms of use remain in force. AI Hub dataset 71894

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "youngseok12/AX-3.1-Light-sft_source_screen_71894_3000"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype="auto",
    device_map="auto",
)

Use the bundled tokenizer chat template for conversational inference. The repository is a merged full model and does not require PEFT adapter loading.

Limitations and license

This model is derived from the Apache-2.0 licensed skt/A.X-3.1-Light model; the base model notices and SK Telecom trademark terms also apply. AI Hub terms apply to the source dataset. See LICENSE and the base model repository for the applicable terms.

The model can produce incorrect, incomplete, biased, or poorly formatted answers. It should not be used as the sole basis for legal, educational, financial, cultural, or other high-impact decisions.
