The Allen Institute for AI (AI2) has launched what it claims is a “actually open supply” massive language mannequin (LLM) and framework: OLMo, described as “state-of-the-art” and made accessible alongside its pre-training information and coaching code.
“Many language fashions right this moment are printed with restricted transparency. With out gaining access to coaching information, 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 with no telescope,” claims OLMo challenge lead Hanna Hajishirzi. “With our new framework, researchers will lastly be capable of examine the science of LLMs, which is vital to constructing the subsequent technology of protected and reliable AI.”

OLMo 7B, AI2 explains, is a big language mannequin (LLM) constructed across the group’s Dolma information set, launched with mannequin weights for 4 variants on the seven-billion scale — therefore its title — 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 doubtless tokens — typically, however not at all times, forming each a coherent and proper reply to a given question.
AI2 goes past releasing the mannequin and its weights, although, and can be making the pre-training information, full coaching information, the code to supply mentioned coaching information, coaching logs and metrics, greater than 500 coaching checkpoints per mannequin, analysis code, and fine-tuning code accessible. 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 just the start for OLMo and the framework,” AI2 claims of its launch. “Work is already underway on completely different mannequin sizes, modalities, datasets, security measures, and evaluations for the OLMo household. Our aim is to collaboratively construct the most effective open language mannequin on this planet, and right this moment we’ve taken step one.”
Extra data on the launch is offered on the AI2 weblog; OLMo itself is offered on Hugging Face and GitHub beneath the permissive Apache 2.0 license.
