Former OpenAI core member Andrej Karpathy chooses Anthropic to return to frontier LLM research

前OpenAI核心成员Andrej Karpathy选择Anthropic重返前沿LLM研究

Andrej Karpathy has joined Anthropic to return to frontline LLM research; the post identifies him as a former OpenAI core team member and Tesla Autopilot architect, but does not disclose his team, title, or specific research projects.

Why it matters: HKR-H/K/R all pass: Karpathy joining Anthropic is a high-signal personnel move in frontier labs. Team, title, and project are undisclosed, so the score stays at the low end of the 85 band.
