[The Past Feud Between Anthropic's Founder and OpenAI's President: Dario Once Banned Brockman from Participating in the Development of ChatGPT's Predecessor Due to 'Project Interference and Marginalizing Researchers'] According to monitoring by Beating, *The Wall Street Journal* revealed that before the core team of Anthropic departed, significant interpersonal conflicts had already arisen internally between OpenAI President Greg Brockman and the Amodei siblings (Dario Amodei and Daniela Amodei). Brockman, a technical prodigy, was known within the company for his assertive and overreaching "bigfooting" management style. He avoided administrative meetings as much as possible, aiming to spend 80% of his time coding, but often intervened in team projects without understanding the context, undermining others' work and drawing numerous complaints from colleagues. Management tensions peaked in OpenAI's early days. Brockman's excessive interference in projects caused a top researcher to feel marginalized, which completely infuriated the then-project lead and future Anthropic founder, Dario Amodei. In response, Amodei took extreme precautionary measures, directly banning Brockman from interfering in the development of the project that eventually led to the creation of ChatGPT. This workplace rift not only contributed to Amodei's team's eventual departure to establish Anthropic but also planted the seeds for future power struggles. During the Thanksgiving 2023 boardroom "coup," one of the core reasons cited by co-founder Ilya Sutskever for ousting Sam Altman was Altman's inability to "keep Brockman in check." The personal relationships between the parties were equally dramatic. In 2018, Brockman fell in love at first sight with Anna, and the two began dating. Daniela Amodei, now the president of Anthropic, was convinced at the time that the relationship wouldn't last and directly bet $100 with Brockman, insisting that Anna would not be his lifelong partner. A year later, the couple got married, holding their wedding at OpenAI's headquarters, with a robotic arm serving as the best man and delivering the wedding rings. Daniela, true to her word, presented a $100 check at the ceremony. After the split between the tech giants, the once-close relationships were irreparably broken. By the end of 2024, as Sutskever (once inseparable from Brockman) officially left OpenAI, the two engaged in excruciating negotiations to retain each other. Ultimately, Brockman's wife Anna sent Sutskever a cactus as a farewell gift, symbolizing the end of an era. [Original Article Link]
