Instructions to use unsloth/granite-4.1-8b with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use unsloth/granite-4.1-8b with Transformers:

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

pipe = pipeline("text-generation", model="unsloth/granite-4.1-8b")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("unsloth/granite-4.1-8b")
model = AutoModelForCausalLM.from_pretrained("unsloth/granite-4.1-8b", device_map="auto")
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=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Is this still overtrained?

In recent experiences with fine-tuning granite, I've come to the realization that it is overtrained. It doesn't react as smoothly as other base models like Gemma or Qwen. 250 training loops does absolutely nothing sometimes, am I just doing it wrong? Is the new 4.1 model going to have the same issues?
