AMD-OLMo

AMD-OLMo are a series of 1B language models trained from scratch by AMD on AMD Instinct™ MI250 GPUs. The training code used is based on OLMo. We release the pre-trained model, supervised fine-tuned model, and DPO aligned model as follows:

AMD-OLMo-1B: Pre-trained on a subset of Dolma v1.7 that consists of 1.3 trillion tokens.
AMD-OLMo-1B-SFT: Supervised fine-tuned (SFT) on Tulu V2 dataset (1st phase) and then OpenHermes-2.5, WebInstructSub, and Code-Feedback datasets (2nd phase).
AMD-OLMo-1B-SFT-DPO: Aligned with human preferences using Direct Preference Optimization (DPO) on UltraFeedback dataset.

Description:

Hardware: Each compute node consists of 4 AMD Instinct™ MI250 GPUs. We use 16 nodes for pretraining AMD-OLMo-1B
Training throughput: 12,200 tokens/sec/gpu
Model architecture: AMD-OLMo-1B is based on the model architecture and training set up of fully open source 1 billion version of OLMo-1B with the details below:

Usage

PyTorch on AMD GPUs

For running pytorch on AMD GPUs you can use the following rocm docker as in docker hub

bash

docker pull rocm/pytorch:latest
# Inside docker
pip install transformers

Use Example

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("amd/AMD-OLMo-1B-SFT").to("cuda") # remove .to("cuda") to load on cpu
tokenizer = AutoTokenizer.from_pretrained("amd/AMD-OLMo-1B-SFT")

prompt = "What is large language model?"
bos = tokenizer.eos_token
template = bos + "<|user|>\n{prompt}\n<|assistant|>\n"

input_text = template.format(prompt=prompt)
inputs = tokenizer([input_text], return_tensors='pt', return_token_type_ids=False).to("cuda")
outputs = model.generate(**inputs, max_new_tokens=1000, do_sample=True, top_k=50, top_p=0.95)
print(tokenizer.batch_decode(outputs, skip_special_tokens=True)[0])

Bias, Risks, and Limitations

The models are being released for research purposes only and are not intended for use cases that require high levels of factuality, safety critical situations, health or medical applications, generating false information, facilitating toxic conversations.
Model checkpoints are made accessible without any safety guarantees. It is crucial for users to conduct comprehensive evaluations and implement safety filtering mechanisms as per their respective use cases.
It may be possible to prompt the model to generate content that may be factually inaccurate, harmful, violent, toxic, biased, or otherwise objectionable. Such content may also get generated by prompts that did not intend to produce output as such. Users are thus requested to be aware of this and exercise caution and responsible thinking when using the model.
Multi-lingual abilities of the models have not been tested and thus may misunderstand and generate erroneous responses across different languages.
