Constellation’s mission is to help the world safely navigate the development of transformative AI.

Our goals

Our goals

In alignment with our mission, we have two primary goals:

1.

Accelerate safety research

We bring together people doing cutting-edge work on the safety of powerful AI systems, enabling them to learn from and collaborate with each other. Many researchers tell us that their research is better or even that their research direction has changed as a result of collaboration at Constellation.

2.

Develop safety talent

Via our fellowships and programs, we support high-potential individuals who want to help the world safely navigate the development of transformative AI. Dozens of participants from our past programs now work full-time on leading safety teams.
