library_name: transformers
base_model:
- sapientinc/HRM-Text-1B
---

This tiny model is intended for debugging. It is randomly initialized using the configuration adapted from [sapientinc/HRM-Text-1B](https://huggingface.co/sapientinc/HRM-Text-1B).

| File path | Size |
|------|------|
| model.safetensors | 2.3MB |


### Example usage:

```python
from transformers import pipeline

model_id = "tiny-random/hrm-text"
pipe = pipeline(
    "text-generation", model=model_id, device="cuda",
    trust_remote_code=True, max_new_tokens=16,
)
print(pipe("Hello World!"))
```
