Stability AI has released its StableLM suite of open-source language models that can be inspected, used, and adapted for research and commercial purposes. The StableLM models are trained on experimental datasets that are three times larger than existing models, making them more efficient and specialized, yet practical. With this move, Stability AI is continuing its commitment to democratizing access to AI technology and fostering transparency and trust in the industry. Developers and researchers can fine-tune the open-source models without sharing their sensitive data or giving up control of their AI capabilities. The StableLM models will power a range of downstream applications and demonstrate how small and efficient models can deliver high performance with appropriate training.
