It is designed by scientists, for scientists.
Installation
First, install PyTorch following the instructions specific to your operating system.
For training and fine-tuning, we recommend installing from source:
git clone https://github.com/allenai/OLMo.git
cd OLMo
pip install -e .[all]
You can also install from PyPI with:
pip install ai2-olmo
Pretraining
OLMo pretraining follows a two-stage training procedure. In the first stage, we train on large amounts of mostly web-based data: OLMo-mix-1124 In the second stage, we train on a smaller amount of high-quality, targeted data: Dolmino-mix-1124
You can find all the checkpoints, at minimum every 1000 training steps, on Huggingface:
Steps to reproduce
To reproduce any of the training processes described below, run this:
torchrun --nproc_per_node=8 scripts/train.py {path_to_train_config}
For the training config, use any of the configs listed below.
If you want to override any of the settings in the training config without having to write a new config every time, you can do this:
torchrun --nproc_per_node=8 scripts/train.py {path_to_train_config} \
--setting1=value \
--setting2=value \
--setting3.subsetting1=value
The training configs below refer to training data that gets streamed in live over HTTP. To reproduce at large scale, we recommend downloading the files locally and changing the paths to point to your local file system.
Note: Some of the files that the training configs refer to are still being uploaded (as of 2024-11-27). They should all appear in the next few days as the uploads complete.
Stage 1
Stage 1 is the biggest stage, where we train on 4T or 5T tokens on largely web-based data.
OLMo2 7B | OLMo2 13B | |
---|---|---|
Number of tokens | 4 Trillion | 5 Trillion |
Checkpoint | stage1-step928646-tokens3896B | stage1-step596057-tokens5001B |
Training config | OLMo2-7B-stage1.yaml | OLMo2-13B-stage1.yaml |
WandB | wandb.ai/…/OLMo2-7B (link to come) | wandb.ai/…/OLMo2-13B (link to come) |
Stage 2 for the 7B
For the 7B model, we train three times with different data order on 50B high quality tokens, and then average ("soup") the models.
Checkpoint | Training config | WandB | |
---|---|---|---|
random seed 42 | stage2-ingredient1-step11931-tokens50B | OLMo2-7B-stage2-seed42.yaml | link to come |
random seed 42069 | stage2-ingredient2-step11931-tokens50B | OLMo2-7B-stage2-seed42069.yaml | link to come |
random seed 666 | stage2-ingredient3-step11931-tokens50B | OLMo2-7B-stage2-seed666.yaml | link to come |
final souped model | main | no config, we just averaged the weights in Python |
The training configs linked here are set up to download the latest checkpoint after stage 1, and start training from there.
Stage 2 for the 13B
For the 13B model, we train three times with different data order on 100B high quality tokens, and one more time on 300B high quality tokens. Then we average ("soup") the models.
Checkpoint | Training config | WandB | |
---|---|---|---|
random seed 1110, 100B | stage2-ingredient1-step11931-tokens100B | OLMo2-13B-stage2-seed1110-100B.yaml | link to come |
random seed 2662, 100B | stage2-ingredient2-step11931-tokens100B | OLMo2-13B-stage2-seed2662-100B.yaml | link to come |
random seed 6209, 100B | stage2-ingredient3-step11931-tokens100B | OLMo2-13B-stage2-seed6209-100B.yaml | link to come |
random seed 2662, 300B | stage2-ingredient4-step11931-tokens300B | OLMo2-13B-stage2-seed2662-300B.yaml | link to come |
final souped model | main | no config, we just averaged the weights in Python |
The training configs linked here are set up to download the latest checkpoint after stage 1, and start training from there.
Instruction tuned variants
For instruction tuned variants of these models, go to
Inference
You can use our Hugging Face integration to run inference on the OLMo Transformers checkpoints:
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])
Alternatively, with the Hugging Face pipeline abstraction:
from transformers import pipeline
olmo_pipe = pipeline("text-generation", model="allenai/OLMo-2-1124-7B")
print(olmo_pipe("Language modeling is"))
Quantization
olmo = AutoModelForCausalLM.from_pretrained("allenai/OLMo-2-1124-7B", torch_dtype=torch.float16, load_in_8bit=True) # requires bitsandbytes
The quantized model is sensitive to input types and CUDA handling. To avoid potential issues, we recommend explicitly converting input IDs to CUDA using: inputs.input_ids.to('cuda')
Evaluation
Additional tools for evaluating OLMo models are available at the OLMo Eval repo.
Modal.com Hosting
An example script is provided for hosting an OLMo 2 model on Modal.com using the OpenAI API in ./scripts/olmo2_modal_openai.py
.
To run that:
- Follow the instructions under Getting Started in the Modal.com Guide to install the Modal library and command line tools.</li>
- Follow the instructions under Secrets in the Modal.com Guide to create a Modal secret named "example-secret-token" that defines a value for the variable MODAL_TOKEN for your server.</li>
- Then run
modal deploy ./scripts/olmo2_modal_openai.py
You can check your endpoint using curl similar to the following:
curl -X POST \
-H "Authorization: Bearer [the secret token from above]" \
-H "Content-Type: application/json" \
-d @body.json \
https://[the web endpoint modal creates above]/v1/chat/completions
where body.json
is of the form:
{
"model": "OLMo-2-1124-13B-Instruct",
"messages": [
{
"role": "user",
"content": "Who was Alan Turing?"
}
],
"max_tokens": 100,
"temperature": 0.9,
"stream": true
}
