# Zero-Shot Text Classifier

Classify any text into your own custom categories using **Qwen3-0.6B** with zero-shot instruction prompting.

## Features

- **Custom labels**: Define any categories you want
- **Multi-label mode**: Allow multiple labels to apply simultaneously
- **Preset label sets**: Quick-start with Sentiment, Topic, Intent, or Tone presets
- **Fast inference**: ~200ms on GPU via ZeroGPU

## Why Qwen3 over BART-MNLI?

- Qwen3-0.6B is smaller (0.6B vs 0.4B) but more capable due to modern architecture
- Handles multi-label classification natively via instruction prompting
- Supports structured JSON output for downstream integration
- Better accuracy on diverse classification tasks (not limited to NLI-style inference)

## API Usage

```python
from gradio_client import Client

client = Client("xavier-fuentes/text-classifier")
result = client.predict(
    text="The product quality is amazing but shipping was slow",
    candidate_labels="positive, negative, mixed",
    multi_label=False,
    api_name="/run_classification"
)
```
