# Granite

[Granite](https://huggingface.co/papers/2408.13359) is a 3B parameter language model trained with the Power scheduler. Discovering a good learning rate for pretraining large language models is difficult because it depends on so many variables (batch size, number of training tokens, etc.) and it is expensive to perform a hyperparameter search. The Power scheduler is based on a power-law relationship between the variables and their transferability to larger models. Combining the Power scheduler with Maximum Update Parameterization (MUP) allows a model to be pretrained with one set of hyperparameters regardless of all the variables.

You can find all the original Granite checkpoints under the [IBM-Granite](https://huggingface.co/ibm-granite) organization.

> [!TIP]
> Click on the Granite models in the right sidebar for more examples of how to apply Granite to different language tasks.

The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`, and from the command line.

<hfoptions id="usage">
<hfoption id="Pipeline">

```python
from transformers import pipeline


pipe = pipeline(
    task="text-generation",
    model="ibm-granite/granite-3.3-2b-base",
    device=0
)
pipe("Explain quantum computing in simple terms ", max_new_tokens=50)
```

</hfoption>
<hfoption id="AutoModel">

```python
from transformers import AutoModelForCausalLM, AutoTokenizer


tokenizer = AutoTokenizer.from_pretrained("ibm-granite/granite-3.3-2b-base")
model = AutoModelForCausalLM.from_pretrained(
    "ibm-granite/granite-3.3-2b-base",
    device_map="auto",
    attn_implementation="sdpa"
)

inputs = tokenizer("Explain quantum computing in simple terms", return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_length=50, cache_implementation="static")
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.

The example below uses [bitsandbytes](../quantization/bitsandbytes) to only quantize the weights to int4.

```python
from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig


quantization_config = BitsAndBytesConfig(load_in_4bit=True)
tokenizer = AutoTokenizer.from_pretrained("ibm-granite/granite-3.3-8b-base")
model = AutoModelForCausalLM.from_pretrained("ibm-granite/granite-3.3-8b-base", device_map="auto", attn_implementation="sdpa", quantization_config=quantization_config)

inputs = tokenizer("Explain quantum computing in simple terms", return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_length=50, cache_implementation="static")
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

quantization_config = BitsAndBytesConfig(load_in_4bit=True)

tokenizer = AutoTokenizer.from_pretrained("ibm-granite/granite-3.3-2b-base")
model = AutoModelForCausalLM.from_pretrained(
    "ibm-granite/granite-3.3-2b-base",
    device_map="auto",
    attn_implementation="sdpa",
    quantization_config=quantization_config,
)

input_ids = tokenizer("Explain artificial intelligence to a 10 year old", return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_length=50, cache_implementation="static")
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
