This tiny model is for debugging. It is randomly initialized with the config adapted from microsoft/phi-4.
Example usage:
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!"))
