Partnerships

We have previously partnered with OpenAI, Anthropic, Google DeepMind, Meta and Amazon to pilot frontier risk assessments. These companies have also provided access and tokens, which we use for evaluations, research, and engineering.

We are also part of the NIST AI Safety Institute Consortium and California Cybersecurity Task Force, are partnering with the AI Security Institute, and provide technical assistance to the European AI Office.
