PrismML is a Pasadena-based artificial intelligence company spun out of Caltech, developing ultra-dense 1-bit and ternary large language models under its Bonsai family. The company emerged from stealth on March 31, 2026, backed by Khosla Ventures and Cerberus Ventures, with compute grants from Google and Caltech and continuing support from Samsung.

The Bonsai lineup spans 27B, 8B, 4B, and 1.7B text models plus Bonsai Image 4B, delivering roughly 14x less memory, 8x faster inference, and 5x less energy for on-device and edge use. PrismML pairs these models with Bonsai Studio, an iOS app, and Hermes, its agentic stack, and is led by founder and CEO Babak Hassibi, a Caltech professor.
