The Allen Institute for AI (AI2) has launched what it claims is a “really open supply” massive language mannequin (LLM) and framework: OLMo, described as “state-of-the-art” and made out there alongside its pre-training knowledge and coaching code.
“Many language fashions at the moment are revealed with restricted transparency. With out gaining access to coaching knowledge, researchers can’t scientifically perceive how a mannequin is working. It is the equal of drug discovery with out medical trials or learning the photo voltaic system and not using a telescope,” claims OLMo mission lead Hanna Hajishirzi. “With our new framework, researchers will lastly be capable to research the science of LLMs, which is crucial to constructing the following technology of protected and reliable AI.”

OLMo 7B, AI2 explains, is a big language mannequin (LLM) constructed across the group’s Dolma knowledge set, launched with mannequin weights for 4 variants on the seven-billion scale — therefore its identify — and one on the one-billion scale, every of which has been skilled to a minimal of two trillion tokens. This places it on a par with different main LLMs, and may imply it delivers the identical type of expertise in taking an enter immediate and delivering a response constructed from probably the most statistically probably tokens — typically, however not all the time, forming each a coherent and proper reply to a given question.
AI2 goes past releasing the mannequin and its weights, although, and can also be making the pre-training knowledge, full coaching knowledge, the code to supply stated coaching knowledge, coaching logs and metrics, greater than 500 coaching checkpoints per mannequin, analysis code, and fine-tuning code out there. This, it argues, will present higher precision than its closed-off rivals, and avoids the necessity to carry out in-house coaching and the computational demand — and carbon output — that entails.

“This launch is only the start for OLMo and the framework,” AI2 claims of its launch. “Work is already underway on totally different mannequin sizes, modalities, datasets, security measures, and evaluations for the OLMo household. Our purpose is to collaboratively construct the most effective open language mannequin on the earth, and at the moment we’ve taken step one.”
Extra data on the launch is accessible on the AI2 weblog; OLMo itself is accessible on Hugging Face and GitHub underneath the permissive Apache 2.0 license.
