ai2-olmo-core 1.3.2

Core training module for the Open Language Model (OLMo)

OLMo-core

Building blocks for OLMo modeling and training

Examples || Docs || PyPI || Beaker Images || License || Changelog

Installation

First install PyTorch according to the instructions specific to your operating system. Then you can install from PyPI with:

pip install ai2-olmo-core

Official training scripts

Official training scripts for various model sizes can be found in src/scripts/train/. To see the exact usage for each script, run the script without any arguments.

Throughput numbers from these scripts with various different configuration settings are reported below, measured on a cluster with NVIDIA H100 GPUs.

Model size	Context length	Precision	Throughput[^1]	Training script	Commandline overrides
1B	4096	BF16	44,000 TPS	OLMo-1B.py
	256-8192[^2]	BF16	49,000 TPS	OLMo-1B.py	--dataset.name=vsl
	4096	FP8	51,000 TPS	OLMo-1B.py	--model.float8_config.enabled=true
7B	4096	BF16	10,000 TPS	OLMo-7B.py
		FP8	13,000 TPS	OLMo-7B.py	--model.float8_config.enabled=true
13B	4096	BF16	4,600 TPS	OLMo-13B.py

[^1]: Throughput reported in tokens per second per device. [^2]: Denotes variable sequence length (VSL) with the Grow-P2 curriculum from Dataset Decomposition: Faster LLM Training with Variable Sequence Length Curriculum.

Development

After cloning OLMo-core and setting up a Python virtual environment, install the codebase from source with:

pip install -e .[all]

The Python library source code is located in src/olmo_core. The corresponding tests are located in src/test. The library docs are located in docs. You can build the docs locally with make docs.

Code checks:

• We use pytest to run tests. You can run all tests with pytest -v src/test. You can also point pytest at a specific test file to run it individually.
• We use isort and black for code formatting. Ideally you should integrate these into your editor, but you can also run them manually or configure them with a pre-commit hook. To validate that all files are formatted correctly, run make style-check.
• We use ruff as our primary linter. You can run it with make lint-check.
• We use mypy as our type checker. You can run it with make type-check.
