Description
This is a LoRA-finetuned codellama/CodeLlama-7b-hf text2SQL model that generates SQLite queries. This is a relatively small model that was fine-tuned on 8 x A10Gs with a total GPU memory of 192GB for over 4 days for 3 epochs. For databases with different SQL syntaxes that do not adhere to SQLite's syntax, we plan to launch other models specifically catered to them.
