# Model Card for OLMo 2 7B |
|
|
|
We introduce OLMo 2, a new family of 7B and 13B models featuring a 9-point increase in MMLU, among other evaluation improvements, compared to the original [OLMo 7B](https://huggingface.co/allenai/OLMo-7B) model. These gains come from training on [OLMo-mix-1124](https://huggingface.co/datasets/allenai/olmo-mix-1124) and [Dolmino-mix-1124](https://huggingface.co/datasets/allenai/dolmino-mix-1124) datasets and staged training approach. |
|
|
|
OLMo is a series of **O**pen **L**anguage **Mo**dels designed to enable the science of language models. |
|
These models are trained on the Dolma dataset. We are releasing all code, checkpoints, logs (coming soon), and associated training details. |

|
|
|
## Installation |
|
|
|
OLMo 2 will be supported in the next version of Transformers, and you need to install it from the main branch using: |
|
```bash |
|
pip install --upgrade git+https://github.com/huggingface/transformers.git |
|
``` |
|
|
|
## Inference |
|
|
|
You can use OLMo with the standard HuggingFace transformers library: |
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
olmo = AutoModelForCausalLM.from_pretrained("allenai/OLMo-2-1124-7B") |
|
tokenizer = AutoTokenizer.from_pretrained("allenai/OLMo-2-1124-7B") |
|
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-2-1124-7B", |
|
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 pretraining, the naming convention is `stepXXX-tokensYYYB`. For checkpoints with ingredients of the soup, the naming convention is `stage2-ingredientN-stepXXX-tokensYYYB` |
|
|
|
|
|
To load a specific model revision with HuggingFace, simply add the argument `revision`: |
|
```bash |
|
olmo = AutoModelForCausalLM.from_pretrained("allenai/OLMo-2-1124-7B", revision="step1000-tokens5B") |
|
``` |
|
|
|
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-2-1124-7B") |
|
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 repository: |
|
```bash |
|
torchrun --nproc_per_node=8 scripts/train.py {path_to_train_config} \ |
|
--data.paths=[{path_to_data}/input_ids.npy] \ |
|
--data.label_mask_paths=[{path_to_data}/label_mask.npy] \ |
|
--load_path={path_to_checkpoint} \ |
|
--reset_trainer_state |
|
``` |
|
For more documentation, see the [GitHub readme](https://github.com/allenai/OLMo?tab=readme-ov-file#fine-tuning). |
|
|
|
2. Further fine-tuning support is being developing in AI2's Open Instruct repository. Details are [here](https://github.com/allenai/open-instruct). |

## 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. |
