This tiny model is for debugging. It is randomly initialized with the config adapted from [microsoft/phi-4](https://huggingface.co/microsoft/phi-4).

### Example usage:

```python
from transformers import pipeline
model_id = "tiny-random/phi-4"
pipe = pipeline(
    "text-generation", model=model_id, device="cuda",
    trust_remote_code=True, max_new_tokens=20,
)
print(pipe("Hello World!"))
```

### Codes to create this repo:

```python

    AutoModelForCausalLM,

    GenerationConfig,
    pipeline,

save_folder = "/tmp/tiny-random/phi-4"

tokenizer = AutoTokenizer.from_pretrained(
    source_model_id, trust_remote_code=True,
)
tokenizer.save_pretrained(save_folder)
