SupportLM: Specialized Customer Support for Indian E-commerce
GuruVarshini/supportlm-qwen2.5-3b is a fine-tuned Qwen2.5-3B-Instruct model specifically designed for customer support in the Indian e-commerce sector. Its primary differentiation lies in its ability to understand and respond to code-switched Hinglish and Tanglish messages, which are common in the region.
Key Capabilities
- Issue Classification: Accurately categorizes customer queries into 8 predefined types (e.g.,
order_status,return_request,payment_issue). Achieves 79.9% classification accuracy on held-out test data, outperforming GPT-4o-mini. - Order ID Extraction: Reliably extracts order IDs from customer messages with 99.4% accuracy.
- Empathetic Response Generation: Crafts empathetic responses in the same code-switched language used by the customer, maintaining a 100% language match rate.
Training and Performance
The model was trained on 1277 synthetic Hinglish/Tanglish examples using QLoRA and DPO methods. It leverages the Qwen/Qwen2.5-3B-Instruct as its base model. The SFT (Supervised Fine-Tuning) version was selected for deployment due to its superior classification accuracy. This model is ideal for automating initial customer support interactions for Indian e-commerce platforms.
