Training Data

The model was trained on 29,750 rows of adapted data with the following domain distribution: science (90%), medical (3%), geography (1%), transportation (1%), product-advice (1%), cooking (1%), agriculture (0%), animal-nature (0%), how-to (0%), architecture-design (0%), history (0%), art (0%), math (0%), academic-education (0%), code (0%), governance (0%), technology (0%), fitness-sports (0%), personal-finance (0%), news (0%), legal (0%), music (0%), religion (0%), fashion-beauty (0%), career-workplace (0%), parenting-family (0%), corporate-business (0%), data-analysis-visualization (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 = "mistralai/Mixtral-8x7B-Instruct-v0.1"
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))
