Anthropic Researcher Resigns Over Safety Concerns, Forfeiting All Equity
An Axios exclusive revealed that an Anthropic researcher (Jacob) resigned only six weeks after joining, forfeiting his equity in the process. The news quickly drew widespread attention and responses from multiple parties.
Confirmed
- Axios reported the researcher's resignation and forfeited equity; zerohedge emphasized that he had been on the job for only six weeks.
- Anthropic safety researcher Ethan Perez confirmed the story: Jacob had a long conversation with him two weeks before leaving, expressing deep concern about the pace of progress after joining Anthropic; Perez tried to persuade him to stay but failed.
- Insider kipperrii added context: Jacob was previously a resident researcher at OpenAI, joined Anthropic out of a desire to help the future go well, and later resigned for the same ideal, giving up substantial compensation—hinting he may move toward nonprofit or safety work.
- Gary Marcus pointed out that the claim of an "entry-level position" is factually wrong: according to Ethan Perez, Anthropic spent two years recruiting Jacob.
Unconfirmed
- Elon Musk speculated the affair "looks like a setup," but without supporting evidence; another user, Jordan Schachtel, raised questions about Jacob Coxon, and the debate continues. limbslong and Marco (AIandDesign) disagree over whether Jacob actually worked 6 weeks or 4 months before resigning, with limbslong demanding a recount.
Why it matters
- This is a rare case where a sitting safety researcher publicly confirmed a departing colleague's concerns about the pace of progress, directly touching on the tension between Anthropic's "safety-first" image and its commercialization speed—making it a focal case for outside scrutiny of AI safety governance.
