What's the endgame? "Anthropic's goal is to make the fundamental research advances that will let us build more capable, general, and reliable AI systems," Dario Amodei said. The funds were earmarked for computationally expensive research into interpretability and steerability — understanding and guiding how models behave.
Why the unusual structure? Anthropic organised as a Public Benefit Corporation from day one, a Delaware structure that binds management to balance profit against a stated public mission. Moskovitz later told POLITICO that "any monetary returns from his investment in Anthropic will be entirely redirected back into our philanthropic work." Tallinn became a board observer.
