Cambridge Boston Alignment Initiative (CBAI) is excited to announce that applications are open for the next iteration of our full-time, paid, in-person Research Fellowship, held from October 13 to December 18 in Harvard Square, Cambridge, MA. We’re selecting up to 40 fellows across two cohorts (AI Safety and AIxBiosecurity), supported by leading mentors and dedicated in-house research managers. Our alumni have joined Goodfire and Constellation, established their own research group, been accepted into NeurIPS and ICLR, and presented their reports to policymakers in DC.

Note: You must have the right to work in the U.S. (i.e., citizenship, residency, or OPT/CPT) to participate in our Fall 2026 fellowship cycle. We are unable to sponsor visas at this time.
