qwq-tiny-random-dim64

This tiny model is for debugging. It is randomly initialized with the config adapted from Qwen/QwQ-32B.

Example usage:

from transformers import pipeline
model_id = "yujiepan/qwq-tiny-random-dim64"
pipe = pipeline(
    "text-generation", model=model_id, device="cuda",
    trust_remote_code=True, max_new_tokens=3,
)
print(pipe("Hello World!"))
