Personnel: Lukasz Kaiser at OpenAI (Researcher)

NoteThe source text is an excerpt from OpenAI's website showing product announcements, research updates, and company news dated between March and April 2026. While the source is about OpenAI (matching the claim's organization), it contains no information about Lukasz Kaiser, his role, or his employment status. The source does not address any of the specific personnel record fields (person, role, startDate). This is unverifiable because the source simply does not discuss the claimed data point, despite being from the correct organization.
