Model Description

This model is a fine-tuned version of Meta's Llama-3.1-8B-Instruct model, created through LoRA fine-tuning on multiple instruction datasets, followed by merging the adapter weights with the base model.

Architecture

• Base Model: meta-llama/Llama-3.1-8B-Instruct
• Size: 8.03B parameters
• Type: Decoder-only transformer
• Format: SafeTensors (full precision)

Training Details

• Training Method: LoRA fine-tuning followed by adapter merging
• LoRA Configuration:
  • Rank: 8
  • Alpha: 16
  • Trainable modules: Attention layers and feed-forward networks
• Training Hyperparameters:
  • Learning rate: 2e-4
  • Batch size: 2
  • Training epochs: 1
  • Optimizer: AdamW with constant scheduler

Intended Use

This model is designed for:

• General purpose assistant capabilities
• Question answering and knowledge retrieval
• Creative content generation
• Instructional guidance

Limitations

• Base model limitations including potential hallucinations and factual inaccuracies
• Limited context window compared to larger models
• Knowledge cutoff from the base Llama-3.1 model
• May exhibit biases present in training data
• Performance on specialized tasks may vary

Usage with Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("utkmst/chimera-beta-test2-lora-merged")
tokenizer = AutoTokenizer.from_pretrained("utkmst/chimera-beta-test2-lora-merged")
