Instructions to use nvidia/Llama3-ChatQA-1.5-70B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use nvidia/Llama3-ChatQA-1.5-70B with Transformers:

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

pipe = pipeline("text-generation", model="nvidia/Llama3-ChatQA-1.5-70B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("nvidia/Llama3-ChatQA-1.5-70B")
model = AutoModelForCausalLM.from_pretrained("nvidia/Llama3-ChatQA-1.5-70B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Multi-lang?

Congrats to the new benchmark results. One difference I could find in command R+ which has very strong multi Lang capabilities to make it a perfect fit for enterprise applications. How about chatqa? Is it also capable of generating text in different languages?

thank you for your question. Unfortunately, ChatQA-1.5 is optimized for English. It could have certain capability to generate other languages if you give it an instruction like, "answer it using French". We observe that the 70B ChatQA model would have a much better capability for this than the 8B model.
