Training Data

The model was trained on 9,339 rows of adapted data with the following domain distribution: culture (48%), language (10%), cooking (10%), history (8%), religion (4%), geography (3%), architecture-design (3%), fitness-sports (2%), governance (2%), agriculture (2%), academic-education (1%), music (1%), art (1%), entertainment (1%), corporate-business (1%), news (0%), legal (0%), travel (0%), transportation (0%), other (0%), science (0%), sports (0%), animal-nature (0%), fashion-beauty (0%), how-to (0%), parenting-family (0%), technology (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 = "google/gemma-3-4b-it-VLM"
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))
