tiny-random/phi-4

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!"))
