What is NSQL-Llama-2-7B?
NSQL-Llama-2-7B is a specialized large language model designed specifically for SQL generation tasks. Built on Meta's Llama-2 7B architecture, this model has been further pre-trained on a massive dataset of general SQL queries and fine-tuned on text-to-SQL pairs, making it particularly adept at converting natural language questions into SQL queries.
Implementation Details
The model underwent a two-stage training process using 80GB A100s with data and model parallelism. The initial pre-training consisted of 3 epochs on 1M SQL queries from The Stack dataset, followed by 10 epochs of fine-tuning on text-to-SQL pairs from over 20 public sources.
