Libraries

How to use google/datagemma-rag-27b-it with Transformers:

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

pipe = pipeline("text-generation", model="google/datagemma-rag-27b-it")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("google/datagemma-rag-27b-it")
model = AutoModelForCausalLM.from_pretrained("google/datagemma-rag-27b-it")
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]:]))

This model uses the same chat template as gemma-2-it?

Hi @apepkuss79 ,

Yes, we can use the same chat template for the google/datagemma-rag-27b-it model because its tokenizer also includes the apply_chat_template function, which returns a chat format identical to that of the gemma-2b-it model.

Thank you.
