ndebuhr/Gemma-2-27B-Technical-Tutorial-Summarization-QLoRA

Model Specifications

• Max Sequence Length: Trained at 16384 (via RoPE Scaling)
• Data Type: Auto detection, with options for Float16 and Bfloat16
• Quantization: 4bit, to reduce memory usage

Training Data

Used a private dataset with hundreds of technical tutorials and associated summaries.

Implementation Highlights

• Efficiency: Emphasis on reducing memory usage and accelerating download speeds through 4bit quantization.
• Adaptability: Auto detection of data types and support for advanced configuration options like RoPE scaling, LoRA, and gradient checkpointing.

Configuration and Usage

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
import torch

input_text = ""

# Set device based on CUDA availability
device = "cuda" if torch.cuda.is_available() else "cpu"

# Load the model and tokenizer
model_name = "ndebuhr/Gemma-2-27B-Technical-Tutorial-Summarization-QLoRA"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name).to(device)

instruction = "Clarify and summarize this tutorial transcript"
prompt = """{}

### Raw Transcript:

# Tokenize the input text
inputs = tokenizer(
    prompt.format(instruction, input_text),
    return_tensors="pt",
    truncation=True,
    max_length=16384
).to(device)

# Generate outputs
outputs = model.generate(

Compute Infrastructure

• Fine-tuning: used 1xA100 (40GB)
• Inference: recommend 1xL4 (24GB)

This gemma2 model was trained 2x faster with Unsloth and Huggingface's TRL library.
