This Space runs an Ark-ASR 0.6B demo with the Transformers backend.

Default runtime limits are set for a single-GPU Space with GPU memory usage
targeted below 15 GB:

- `ARK_ASR_MAX_AUDIO_SECONDS=30`
- `ARK_ASR_DTYPE=float16`
- `ARK_ASR_ATTN_IMPL=sdpa`
- Gradio queue concurrency is limited to one request.

For local testing on this machine, use the local checkpoint instead of pulling
from the Hub:

```bash
scripts/run_local_gradio.sh
```
