Preferred Networks is an AI company based in Tokyo working across the stack, from AI chips and computing infrastructure to LLMs and products. You may already know us indirectly if you\'ve used software we\'ve built, such as Optuna or CuPy (or Chainer, back in the day). We are designing in-house chips (MN-Core series) and training LLMs (PLaMo series). Our team is actively hiring for two roles related to these endeavors.
