Model Card for OLMo 7B Instruct

OLMo is a series of O pen L anguage Mo dels designed to enable the science of language models. The OLMo base models are trained on the Dolma dataset. The adapted versions are trained on the Tulu SFT mixture and, for the Instruct version, a cleaned version of the UltraFeedback dataset . We release all code, checkpoints, logs, and details involved in training these models.

OLMo 7B Instruct and OLMo SFT are two adapted versions of these models trained for better question answering. They show the performance gain that OLMo base models can achieve with existing fine-tuning techniques.

This version is for direct use with HuggingFace Transformers from v4.40 on.

Model Details

We release two adapted model versions: The base models related to this adapted model are the following:

Uses

Inference

You can load and run this model as usual so long as your HuggingFace version is >= 4.40:

from transformers import AutoModelForCausalLM, AutoTokenizer
olmo = AutoModelForCausalLM.from_pretrained("allenai/OLMo-7B-Instruct-hf")
tokenizer = AutoTokenizer.from_pretrained("allenai/OLMo-7B-Instruct-hf")
message = [{"role": "user", "content": "What is 2+2?"}]
inputs = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt")
# 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])
>> '2+2=4'

Evaluation

Core model results for the 7B adapted models are found below.

*Following Ivison et al. 2023, we do not report Tulu 2 TruthfulQA scores due to test set contamination.

Model Details

Data

For training data details, please see the Dolma , Tulu 2 , and UltraFeedback documentation.

Architecture

Hyperparameters

The hyperparameters for the two phases of training are below:

Compared to Tulu 2, DPO hyperparameters are the same. SFT is lower LR and 3 epochs instead of 2 (and 2k length instead of 8k).

Bias, Risks, and Limitations

This adapted OLMo model is a research artifact. It is intended to benefit the research community interested in understanding the safety properties of LLMs and developers building safety tools for LLMs. For this reason, the model does not include a specific safety filter or safety training data. While our model scores well relative to its peers on ToxiGen, it is possible for the model to generate harmful and sensitive content from some user prompts. We recommend developers exercise caution and consider the risks of the applications of this technology. Furthermore, developers should consider implementing safeguards for biases, privacy, and other potential harms when appropriate. Finally, as with every LLM, OLMo may produce factual-sounding outputs that may not be true, so developers and users are encouraged to confirm such outputs before relying on them. All users of this model are responsible for how they use the model.
