Tiny OpenHermes: A Compact Conversational Model

Havoc999/tiny-openhermes is a 1.1 billion parameter language model, fine-tuned from TinyLlama/TinyLlama-1.1B-Chat-v1.0 using LoRA (rank 32) on the teknium/OpenHermes-2.5 dataset. This model was trained for 1 epoch on Kaggle Dual T4 GPUs, focusing on conversational capabilities.

Key Capabilities & Performance

This model, despite its small size, exhibits baseline performance in common NLP tasks. It is primarily English-focused due to its training data. Benchmark results using the Language Model Evaluation Harness indicate:

  • PIQA (Physical Commonsense): 72.03% normalized accuracy
  • HellaSwag (Commonsense Reasoning): 59.20% normalized accuracy
  • ARC-Challenge (Advanced Science): 29.69% normalized accuracy
  • MMLU (Mathematics): 26.13% accuracy

Limitations

As a 1.1 billion parameter model, it has inherent limitations:

  • English-primary: Predominantly English due to the OpenHermes-2.5 dataset.
  • Hallucination: May hallucinate facts; verification of important claims is necessary.
  • Complex Reasoning: Can struggle with complex, multi-step reasoning tasks.
  • Alignment: Its safety alignment is based on TinyLlama's base alignment and is not further RLHF-aligned.
