This model has been xMADified!
This repository contains google/gemma-2-9b-it
quantized from 16-bit floats to 4-bit integers, using xMAD.ai proprietary technology.
Why should I use this model?
Accuracy: This xMADified model is the best quantized version of the
google/gemma-2-9b-it
model (8 GB only). See Table 1 below for model quality benchmarks.Memory-efficiency: The full-precision model is around 18.5 GB, while this xMADified model is only around 8 GB, making it feasible to run on a 12 GB GPU.
Fine-tuning: These models are fine-tunable over the same reduced (12 GB GPU) hardware in mere 3-clicks. Watch our product demo here

Sample Inference Code
from transformers import AutoTokenizer
from auto_gptq import AutoGPTQForCausalLM
model_id = "xmadai/gemma-2-9b-it-xMADai-INT4"
prompt = [
{"role": "system", "content": "You are a helpful assistant, that responds as a pirate."},
{"role": "user", "content": "What's Deep Learning?"},
]
tokenizer = AutoTokenizer.from_pretrained(model_id, use_fast=False)
inputs = tokenizer.apply_chat_template(
prompt,
tokenize=True,
add_generation_prompt=True,
return_tensors="pt",
return_dict=True,
).to("cuda")
model = AutoGPTQForCausalLM.from_quantized(
model_id,
device_map='auto',
trust_remote_code=True,
)
outputs = model.generate(**inputs, do_sample=True, max_new_tokens=1024)
print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
