HyperCLOVA X SEED Think-14B — AI Hub 71875 Base-correct Minimal SFT
This repository contains a standalone BF16 model derived from naver-hyperclovax/HyperCLOVAX-SEED-Think-14B. A deliberately minimal LoRA adapter was trained on the Base-correct pool from AI Hub dataset 71875 and merged into the pristine base weights.

Training data
The training pool contains 1,725 rows selected from the 3,000-row AI Hub 71875 K_train source after a pristine Base label probe: the Base model produced an unambiguous correct answer label on these rows. The pool contains 509 internal-medicine, 497 obstetrics-and-gynecology, 462 pediatrics, and 257 emergency-medicine rows. Uncertain rows (669) were excluded. Training targets are the gold A–D answer labels; the Base model's output is not included as a training target.

model_id = "youngseok12/HyperCLOVA-X-SEED-Think-14B-sft-71875-correct-minimal"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id, dtype=torch.bfloat16, device_map="auto"
)

inputs = tokenizer.apply_chat_template(
messages, add_generation_prompt=True, tokenize=True, return_tensors="pt"
).to(model.device)
with torch.inference_mode():
outputs = model.generate(**inputs, max_new_tokens=64, do_sample=False)
