# Text-to-SQL Prospect Model (Approach B: Schema-Linking)
Fine-tuned QLoRA adapter for **Qwen2.5-Coder-3B-Instruct** designed to generate SQL queries in French for the `companies` database schema.
## Model Details
- **Base Model**: `Qwen/Qwen2.5-Coder-3B-Instruct`
- **Adapter Repo**: `axrafTic/text2sqlProspeciton`
- **Method**: QLoRA Fine-Tuning (`r=32`, `alpha=64`, target modules: all linear layers)
- **Task**: Text-to-SQL (French natural language questions -> SQLite / Postgres SQL queries)
- **Approach**: Schema-Linking with column annotations (`SCHEMA_B`)
## Prompt Structure (ChatML)
