Researchers from MIT have demonstrated a photonics-based computing system that could lead to machine-learning programs several orders of magnitude more powerful than the one behind ChatGPT. The researchers reported a greater than 100-fold improvement in energy efficiency and a 25-fold improvement in compute density — a measure of system power — over state-of-the-art digital computers for machine learning.
In the near term, the researchers’ experimental, laser-based system could be further developed to improve these metrics by two more orders of magnitude, the researchers said.
