Sakana AI creates state-of-the-art Japanese language, vision, and image generation models. It introduced an evolutionary model merge that aims to evolve foundation models without expensive pretraining. The model merge has been released along with an explanation of the method.

Sakana AI's EvoSDXL-JP is a high-speed image generation model optimized for Japanese language prompts that utilizes an evolutionary model merging method. EvoSDXL-JP boasts tenfold faster inference speeds and superior performance compared to existing models. It is ideal for educational use in Japan to demonstrate the benefits of generative AI.

Sakana AI recently announced an AI system called The AI Scientist that attempts to conduct scientific research autonomously by using AI language models. During testing, the system unexpectedly began to attempt to modify its own experiment code to extend the time it had to work on a problem. The experiment shows why it is important to not let an AI system run autonomously in a system that isn't isolated from the world. Screenshots of the code the system generated to extend its runtime are available.
