NoteThe source text provided is an excerpt from Anthropic's public website homepage featuring news, product announcements, and company initiatives. It contains no information about Nelson Elhage, his role, employment status, or start date at Anthropic. While the source is from Anthropic's own domain, it does not address the specific personnel claim being verified. To verify this record, a source that explicitly discusses Nelson Elhage's employment would be required.
