# Customer Support LoRA Adapter (Llama-3.2-3B-Instruct · MLX)

This repository provides **LoRA adapters** fine-tuned on the
[Bitext Customer Support dataset](https://huggingface.co/datasets/bitext/Bitext-customer-support-llm-chatbot-training-dataset).
The goal is **placeholder-safe** answers (e.g., `{{Order Number}}`, `{{Website URL}}` **must remain unchanged**).

- **Base model**: [`meta-llama/Llama-3.2-3B-Instruct`](https://huggingface.co/meta-llama/Llama-3.2-3B-Instruct)  
- **Runtime**: Apple Silicon **MLX**  
- **This repo contains**: `adapters.safetensors` (**LoRA only**; no base weights)

> You must accept/download the base model under its own license (Meta Llama 3.2 Community License).  
> This repo **does not** include base weights.

## Quickstart (MLX CLI)

Install once:
```bash
pip install -U mlx-lm

Generate with adapter:
python -m mlx_lm.generate \
  --model meta-llama/Llama-3.2-3B-Instruct \
  --adapter-path batuhne/customer-support-llm \
  --prompt "Hello, please cancel order {{Order Number}}" \
  --max-tokens 128 --temp 0.2

Interactive chat (optional):
python -m mlx_lm.chat \
  --model meta-llama/Llama-3.2-3B-Instruct \
  --adapter-path batuhne/customer-support-llm

Recommended system prompt
Keep placeholders exactly:
You are a concise, helpful customer support agent. Preserve placeholders exactly as given (e.g., {{Order Number}}, {{Website URL}}).

Notes
Trained for placeholder integrity; do not modify {{…}} tokens in outputs.
Use MLX quantized base weights if you need lower RAM/VRAM usage on Apple Silicon.

Limitations
Adapter quality is tied to the base model and dataset scope (customer support).
This is not a general safety or policy layer; review outputs before production use.
