MamayLM-Gemma-3-12B-IT-v1.0-FP8-Static-Nadiia-v2

Model description

MamayLM-Gemma-3-12B-IT-v1.0-FP8-Static-Nadiia-v2 is an FP8 static-quantized version of the instruction-tuned INSAIT-Institute/MamayLM-Gemma-3-12B-IT-v1.0. based on Gemma 3 12B model, prepared for efficient inference while preserving quality for Ukrainian-language assistant workloads.

This version was quantized on a NVIDIA B200 GPU using the private Nadiia-v2 dataset for calibration.

Intended use

This model is intended for:

• Ukrainian-language assistant scenarios
• Instruction following
• Customer support and helpdesk-style conversations
• General text generation
• Evaluation of FP8 static quantization quality/performance trade-offs

Quantization Details

• Base instruction model: INSAIT-Institute/MamayLM-Gemma-3-12B-IT-v1.0.
• Quantization format: FP8 static quantization (E4M3)
• Calibration dataset: private dataset Nadiia-v2
• Quantization hardware: NVIDIA B200 GPU

Usage

Transformers

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "oshkorinova/MamayLM-Gemma-3-12B-IT-v1.0-FP8-Static-Nadiia-v2"

tokenizer = AutoTokenizer.from_pretrained(
    model_id,
    trust_remote_code=True,
)

model = AutoModelForCausalLM.from_pretrained(
    model_id,
    device_map="auto",
    trust_remote_code=True,
    torch_dtype="auto",
)

messages = [
    {"role": "user", "content": "Поясни простими словами, що таке квантізація моделі."}
]

inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_tensors="pt",
).to(model.device)

with torch.no_grad():
    outputs = model.generate(
        inputs,
        max_new_tokens=200,
        do_sample=True,
        temperature=0.7,
    )

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
