Model Overview

The samudradino/pgabl-legal-chatbot is a 1.5 billion parameter instruction-tuned language model, developed by samudradino. It is finetuned from the unsloth/Qwen2.5-1.5B-Instruct-bnb-4bit base model, indicating its foundation in the Qwen2.5 architecture.

Key Characteristics

  • Base Model: Finetuned from unsloth/Qwen2.5-1.5B-Instruct-bnb-4bit.
  • Parameter Count: Features 1.5 billion parameters, offering a balance between performance and computational efficiency.
  • Context Length: Supports a substantial context window of 32768 tokens, enabling processing of longer inputs and maintaining conversational coherence over extended interactions.
  • Training Efficiency: The model was trained using Unsloth and Huggingface's TRL library, which facilitated a 2x faster training process.

Intended Use Cases

This model is specifically designed for chatbot applications, particularly within the legal domain. Its instruction-tuned nature and large context window make it suitable for tasks requiring detailed understanding and generation of legal-related text, such as:

  • Answering legal queries.
  • Summarizing legal documents.
  • Assisting with legal research.
  • Generating legal-themed conversational responses.
