Libraries

How to use nvidia/Nemotron-H-47B-Reasoning-128K with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="nvidia/Nemotron-H-47B-Reasoning-128K")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoModel
model = AutoModel.from_pretrained("nvidia/Nemotron-H-47B-Reasoning-128K", device_map="auto")
