What is h2o-danube2-1.8b-chat?

h2o-danube2-1.8b-chat is an advanced language model developed by H2O.ai, representing a sophisticated chat-tuned variant of their 1.8B parameter architecture. Built on a modified Llama 2 architecture and utilizing the Mistral tokenizer, this model has been optimized through both Supervised Fine-Tuning (SFT) and Direct Preference Optimization (DPO) to enhance its conversational capabilities.

Implementation Details

The model features a carefully balanced architecture with 24 layers, 32 attention heads, and 8 query groups. It employs a 2560-dimensional embedding space and operates with a vocabulary size of 32,000 tokens. The model supports an impressive context length of 8,192 tokens, making it suitable for handling extended conversations and complex tasks.

  • 24 transformer layers with advanced attention mechanisms
