# Model Card for OLMo 7B April 2024 SFT |
|
|
|
**Requires transformers versions v4.40.0 or newer** |
|
|
|
|
|
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](https://huggingface.co/datasets/allenai/dolma) dataset. |
|
The adapted versions are trained on the [Tulu SFT mixture](https://huggingface.co/datasets/allenai/tulu-v2-sft-mixture-olmo-4096) and, for the Instruct version, a [cleaned version of the UltraFeedback dataset](https://huggingface.co/datasets/allenai/ultrafeedback_binarized_cleaned). |
|
|
|
OLMo 7B April 2024 Instruct and OLMo SFT are two adapted versions of these models trained for better question answering. |
|
They are based on the OLMo 7B April release (previously called OLMo 1.7). |
|
They show the performance gain that OLMo base models can achieve with existing fine-tuning techniques. |
|
|

|
### Inference |
|
|
|
You can run these models using recent (>= 4.40) versions of transformers. |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
olmo = AutoModelForCausalLM.from_pretrained("allenai/OLMo-7B-0424-Instruct-hf") |
|
tokenizer = AutoTokenizer.from_pretrained("allenai/OLMo-7B-0424-Instruct-hf") |
|
chat = [ |
|
{ "role": "user", "content": "What is language modeling?" }, |
|
] |
|
prompt = tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True) |
|
inputs = tokenizer.encode(prompt, add_special_tokens=False, return_tensors="pt") |
|
# optional verifying cuda |
|
# inputs = {k: v.to('cuda') for k,v in inputs.items()} |
|
# olmo = olmo.to('cuda') |
|
response = olmo.generate(input_ids=inputs.to(olmo.device), max_new_tokens=100, do_sample=True, top_k=50, top_p=0.95) |
|
print(tokenizer.batch_decode(response, skip_special_tokens=True)[0]) |
|
>> '<|user|>\nWhat is language modeling?\n<|assistant|>\nLanguage modeling is a type of natural language processing (NLP) task or machine learning task that...' |
|
``` |
|
|
|
You can make this slightly faster by quantizing the model, e.g. `OLMoForCausalLM.from_pretrained("allenai/OLMo-7B-Instruct", torch_dtype=torch.float16, load_in_8bit=True)` (requires `bitsandbytes`). |
|
The quantized model is more sensitive to typing / cuda, so it is recommended to pass the inputs as `inputs.input_ids.to('cuda')` to avoid potential issues. |
|

## Model Details |
|
|
|
### Data |
|
For training data details, please see the [Dolma](https://huggingface.co/datasets/allenai/dolma), [Tulu 2](https://huggingface.co/datasets/allenai/tulu-v2-sft-mixture-olmo-4096), and [UltraFeedback](https://huggingface.co/datasets/openbmb/UltraFeedback) documentation. |
|
|
|
### Architecture |
|
|
|
|
|
### Hyperparameters |
|
|
|
The hyperparameters for the two phases of training are below: |
|
|
|
| | Learning Rate | Beta | Epochs | Warmup | Weight Decay | Gradient Clipping | Maximum Sequence Length | |
|
|-------------------------|---------------|------|--------|------------------------------------------------------------------------|--------------|-------------------|-------------------------| |
|
| **SFT** | 2 × 10^-6 | N/A | 3 | Linear warmup for the first 3% of total training time, then cooldown to 0 | 0 | 0 | 4096 | |
|
| **DPO** | 5 × 10^-7 | 0.1 | 3 | Linear warmup for the first 10% of total training time, then cooldown to 0| 0 | 0 | 4096 | |
|
|
|
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. |
