Hembot-7B-v1 Overview

Hembot-7B-v1 is a 7.6 billion parameter language model developed by hemlang, built upon the hemlang/Hemlock-Apothecary-7B base model. It was fine-tuned using the ORPO (Odds Ratio Preference Optimization) training method, which is designed to align the model's outputs with human preferences more effectively.

Key Technical Specifications

  • Base Model: hemlang/Hemlock-Apothecary-7B
  • Training Method: ORPO
  • Parameter Count: 7.6 billion
  • Max Sequence Length: 2048 tokens
  • Quantization: 4-bit (NF4)
  • Optimizer: paged_adamw_8bit
  • LoRA Configuration: Rank 32, Alpha 64, Dropout 0.05, targeting up_proj, down_proj, gate_proj, k_proj, q_proj, v_proj, o_proj modules.

Training Details

The model underwent 8 epochs of training with a batch size of 4 and a gradient accumulation of 4, resulting in an effective batch size of 16. A cosine learning rate scheduler was used with a warmup ratio of 0.05. The training process also incorporated a maximum gradient norm of 0.1 and a beta value of 0.1 for the ORPO objective.

Potential Use Cases

Given its ORPO-based fine-tuning, Hembot-7B-v1 is well-suited for applications requiring:

  • Preference-aligned text generation: Tasks where outputs need to conform to specific stylistic or content preferences.
  • Instruction following: Generating responses that accurately follow given instructions.
  • General language understanding and generation: A versatile model for various NLP tasks within its context window and parameter size.
