# Model Card for Olmo-3.1-32B-Instruct

We introduce Olmo 3, a new family of 7B and 32B models both Instruct and Think variants. Long chain-of-thought thinking improves reasoning tasks like math and coding.

Olmo is a series of **O**pen **l**anguage **mo**dels designed to enable the science of language models. 
These models are pre-trained on the Dolma 3 dataset and post-trained on the Dolci datasets. We are releasing all code, checkpoints, logs (coming soon), and associated training details. 



The core models released in this batch include the following:

| **Stage**               | **Olmo 3 7B Think** | **Olmo (3/3.1) 32B Think** | **Olmo 3 7B Instruct** | **Olmo 3.1 32B Instruct** |

## Installation

Olmo 3 is supported in transformers 4.57.0 or higher:
```bash
pip install transformers>=4.57.0
```

## Inference

You can use OLMo with the standard HuggingFace transformers library:
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
olmo = AutoModelForCausalLM.from_pretrained("allenai/Olmo-3.1-32B-Instruct")
tokenizer = AutoTokenizer.from_pretrained("allenai/Olmo-3.1-32B-Instruct")
message = ["Language modeling is "]
inputs = tokenizer(message, return_tensors='pt', return_token_type_ids=False)
# optional verifying cuda
# inputs = {k: v.to('cuda') for k,v in inputs.items()}
# olmo = olmo.to('cuda')
response = olmo.generate(**inputs, max_new_tokens=100, do_sample=True, top_k=50, top_p=0.95)
print(tokenizer.batch_decode(response, skip_special_tokens=True)[0])
>> 'Language modeling is  a key component of any text-based application, but its effectiveness...'
```

For faster performance, you can quantize the model using the following method:
```python
AutoModelForCausalLM.from_pretrained("allenai/Olmo-3.1-32B-Instruct", 
    torch_dtype=torch.float16, 
    load_in_8bit=True)  # Requires bitsandbytes
```
The quantized model is more sensitive to data types and CUDA operations. To avoid potential issues, it's recommended to pass the inputs directly to CUDA using:
```python
inputs.input_ids.to('cuda')
```

We have released checkpoints for these models. For post-training, the naming convention is `step_XXXX`. 
**NOTE**: For this model, due to a checkpointing issue, we only are releasing the final few checkpoints. See our other RL jobs for more detailed intermediate checkpoint suite.

To load a specific model revision with HuggingFace, simply add the argument `revision`:
```bash
olmo = AutoModelForCausalLM.from_pretrained("allenai/Olmo-3.1-32B-Instruct", revision="step_1375")
```

Or, you can access all the revisions for the models via the following code snippet:
```python
from huggingface_hub import list_repo_refs
out = list_repo_refs("allenai/Olmo-3.1-32B-Instruct")
branches = [b.name for b in out.branches]
```

### Fine-tuning
Model fine-tuning can be done from the final checkpoint (the `main` revision of this model) or many intermediate checkpoints. Two recipes for tuning are available.
1. Fine-tune with the OLMo-core repository:
```bash
torchrun --nproc-per-node=8 ./src/scripts/official/MODEL.py run01
```
You can override most configuration options from the command-line. For example, to override the learning rate you could launch the script like this:

```bash
torchrun --nproc-per-node=8 ./src/scripts/train/MODEL.py run01 --train_module.optim.lr=6e-3
```

## Bias, Risks, and Limitations
Like any base language model or fine-tuned model without safety filtering, these models can easily be prompted by users to generate harmful and sensitive content. Such content may also be produced unintentionally, especially in cases involving bias, so we recommend that users consider the risks when applying this technology. Additionally, many statements from OLMo or any LLM are often inaccurate, so facts should be verified.
