Training Data

The model was trained on 490 rows of adapted data with the following domain distribution: code (45%), science (29%), math (14%), technology (3%), religion (2%), writing-editing-communication (1%), history (1%), medical (1%), governance (1%), legal (0%), entertainment (0%), travel (0%), cooking (0%), culture (0%), academic-education (0%), other (0%), fashion-beauty (0%), personal-growth (0%), art (0%), how-to (0%), language (0%), geography (0%), agriculture (0%), product-advice (0%), parenting-family (0%), architecture-design (0%), hr (0%), games (0%), music (0%), sports (0%), marketing (0%), philosophy (0%), animal-nature (0%), transportation (0%), market-analysis (0%), career-workplace (0%).

Model Evaluation

The model was evaluated on an in-distribution held-out test set as well as a broader domain-specific test set to measure generalization.

How to use

pip install torch transformers peft

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

BASE = "openai/gpt-oss-20b"
ADAPTER = "<this-repo-id>"

device = "cuda" if torch.cuda.is_available() else "cpu"
dtype = torch.float32 if device == "cpu" else torch.bfloat16

base = AutoModelForCausalLM.from_pretrained(BASE, dtype=dtype).to(device)
model = PeftModel.from_pretrained(base, ADAPTER)
# Optional: merge the LoRA weights into the base for faster inference
model = model.merge_and_unload()
model.eval()

tokenizer = AutoTokenizer.from_pretrained(BASE)
messages = [{"role": "user", "content": "Hello!"}]
text = tokenizer.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(device)

with torch.inference_mode():
    out = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(out[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))
