Unlock the full potential of language modeling with OLMo, the pinnacle of open-source language initiatives. Standing out with a unique ethos of total transparency, OLMo revolutionizes how we interact with, understand, and develop language models by sharing everything - yes, every single element of the project - from its 3 trillion token Dolma dataset to vital resources like training code, model weights, inference code, and detailed logs.

Dive into a world where reproducing the model training process, delving into performance intricacies, and customizing the model to your needs is not just possible—it’s encouraged. OLMo’s commitment to a 100% open-source framework paves the way for unmatched research opportunities, enabling you to:

  • Access comprehensive pre-training data with the AI2 Dolma dataset, offering a rich open corpus that covers 500 million documents sourced from diverse platforms. This foundation allows you to explore the depths of the model’s learning process and adapt it to fit various research goals.
  • Utilize full model weights and training code for four different variant models, each trained with at least 2 trillion tokens. Whether you’re aiming to replicate the training process or fine-tune the model’s performance, OLMo equips you with all the resources you need.
  • Benefit from an extensive evaluation toolkit, featuring more than 500 model checkpoints and evaluation code from the Catwalk project. Assess your models or deepen your analysis of OLMo with precision.

Model Parameters and Architecture Details:

Explore a variety of model sizes tailored to your project needs, from the 1 billion parameter model boasting 16 layers and 2048 hidden units per layer to the colossal 65 billion parameter variant, still expanding its capabilities with 80 layers and 8192 hidden units per layer. OLMo models, built on a decoder-only Transformer architecture, incorporate innovations like non-parametric layer normalization and SwiGLU activation functions to refine performance further.

Performance Evaluation:

Benchmarked alongside leading models, OLMo 7B demonstrates comparable results in generation and reading comprehension tasks and exhibits promising potential across a spectrum of applications. Through AI2’s Paloma and available checkpoints, delve into comprehensive analyses linking model predictability with size and training.
