# JevAlt: try small English, Turkish and German decision models

Try small language models for text classification and decisions with probabilities: Deem-4B in English, Karar-4B in Turkish and Wähler-4B in German. **Karar-4B scores 96.8% against Kev-4B's 87.1%** on held-out Turkish decisions from the training data pipeline. This result measures that decision task.

## Try a decision

Choose a language and an example, then press **Decide**. Or enter a situation, a question and the possible answers. Each option returns a probability. Select **Allow “unknown”** when the deciding fact may be missing.

[Open the decision app](https://mertkayacs-jevalt.hf.space). Use synthetic examples; the public Space receives the text you submit. Run locally for private data.

## Call from Python

```python
import json
from gradio_client import Client

request = {
    "state": "I was charged twice for my subscription.",
    "questions": {
        "team": {
            "type": "choice",
            "instructions": "Which team should handle this ticket?",
            "criteria": {"billing": "payments, refunds", "technical": "bugs, outages"},
        }
    },
    "reasoning": "off",
    "abstain": False,
}
print(Client("mertkayacs/JevAlt").predict(json.dumps(request), "en", api_name="/decide"))
```

Use `tr` or `de` for Turkish or German, with the request written in that language. Install `gradio_client` for this example.

## Models and limits

| Model | Language | Held-out accuracy | Kev-4B accuracy |
|---|---|---|---|
| [Deem-4B](https://huggingface.co/mertkayacs/Deem-4B) | English | 94.7% | 84.7% |
| [Karar-4B](https://huggingface.co/mertkayacs/Karar-4B) | Turkish | 96.8% | 87.1% |
| [Wähler-4B](https://huggingface.co/mertkayacs/Wahler-4B) | German | 92.0% | 81.1% |

The tests share the training data pipeline. Planted instructions, long irrelevant text and date arithmetic remain failure cases. Refit calibration before using probabilities as thresholds, and review consequential decisions. [Recorded examples and test results](https://huggingface.co/datasets/mertkayacs/jevalt-bench).
