4 src · 4 checksNoteThe source text provided does not address any of the claims in the record (person name, organization, role, or start date). The excerpt appears to be a corrupted or incomplete webpage fragment about Claude models and contains no information relevant to verifying Jan Leike's employment at Anthropic or his role as Head of Alignment Science. Without source material that actually discusses the personnel record, the claims cannot be verified.
NoteThe source confirms Jan Leike works at Anthropic and is associated with alignment science work. However, the source describes him as 'co-lead of the Alignment Science team' rather than 'Head of Alignment Science'. These are different titles—'co-lead' implies shared leadership with others, while 'Head' suggests sole leadership. The source also confirms he joined in 2024 (matching the 2024-05 start date claim), but does not specify May 2024. The core facts are confirmed but the specific job title differs.
NoteThe source confirms Jan Leike works at Anthropic in the Alignment Science team, but states he 'leads' the team, not 'co-leads' it. The source does not mention a co-lead arrangement at Anthropic. The startDate of 2024-05 cannot be verified from the source text, which does not provide specific joining dates. The role title is partially inaccurate (lead vs. co-lead), making this a partial confirmation rather than full confirmation.
NoteThe source confirms Jan Leike joined Anthropic in May 2024 (matching the startDate of 2024-05) and confirms he leads a team focused on alignment work. However, the source describes his role as leading a 'superalignment' team working on specific technical areas (scalable oversight, weak-to-strong generalization, automated alignment research), not explicitly as 'Head of Alignment Science.' The role title in the record is not directly stated in the source text, making it unverifiable whether 'Head of Alignment Science' is the official title used by Anthropic, though the substance of the role (leading alignment work) is confirmed.
