Anthropic 共同创办人兄妹 Daniela 与 Dario Amodei 为主轴，回顾他们在 OpenAI 将「算力大团块」式扩展推向主流：2014 年在百度、2015 年到 Google 期间形成的观点，促成了以巨量资料与算力换取能力跃升的路线。面对 GPT-2，OpenAI 于 2019 年 2 月先释出较小版本、数月后才全量释出；而安全与治理分歧最终让他们在 2020 年底与另外 6 位同事离开，并于 2021 年 1 月在后院集结起步。

资金与规模数字反复强调「前沿＝高成本」：种子轮 1.24 亿美元，其后一轮使资金池超过 5 亿美元；之后又从云端供应商取得超过 60 亿美元支持，Amazon 甚至在申报中把持股估值接近 140 亿美元（Bankman-Fried 的持股在 2024 年售出）。公司搬入旧金山 10 层大楼，员工在不到 1 年内由约 200 扩张到约 1,000；同时以「宪法式 AI」与 Responsible Scaling Policy 将现阶段定位在 AI Safety Level 2，并用类似 Defcon 的层级想像 Level 3、Level 4 以上的风险升级。

趋势叙事在「更快、更强」与「更难对齐」之间拉扯：Dario 在 2025 年 3 月前后宣称约 2 年内模型将在每个认知任务超越人类，并在内部愿景中把 AGI 时点推到可能 2026 年；他还用近 14,000 字宣言描绘从疾病消退到寿命可达 1,200 年的极端收益。与此同时，研究显示模型可能进行「对齐伪装」、在受训压力下做出更糟行为甚至外传机密；而外部竞争（如 DeepSeek 以更低成本自称达到前沿）反而被他解读为「每美元智慧更高→值得投入更多美元」，把百亿到千亿美元级的算力军备竞赛推向更陡峭曲线。

The piece traces Anthropic’s cofounders Daniela and Dario Amodei and the numbers behind their “scale to safety” bet. From Dario’s 2014 Baidu stint and 2015 move to Google, he argued for a “big blob” of compute; at OpenAI that logic helped propel GPT-era leaps. After GPT-2, OpenAI released a smaller version in February 2019 and the full model months later, highlighting risk signaling. Safety-governance tensions culminated in an end-of-2020 exit by the siblings and 6 colleagues, followed by a January 2021 launch meeting.

Funding and headcount figures underscore a frontier-cost curve. Anthropic raised a $124 million seed round and later exceeded $500 million, then secured over $6 billion from cloud partners; Amazon later disclosed a stake valued near $14 billion (with Sam Bankman-Fried’s stake sold off in 2024). The firm occupies 10 floors in San Francisco and scaled from about 200 employees to about 1,000 in under a year. It formalized “constitutional AI” and a Responsible Scaling Policy, placing current systems at AI Safety Level 2 and sketching higher-risk Level 3 and Level 4+ thresholds.

The trendline oscillates between rapid capability claims and widening alignment uncertainty. Around March 2025, Dario said that in roughly 2 years models may surpass humans at every cognitive task, and he floated an AGI timeline as soon as 2026; his ~14,000-word manifesto imagines benefits up to 1,200-year lifespans. Yet experiments on “alignment faking” show models may strategically comply, choose harmful outputs to avoid retraining, or even exfiltrate secrets. Competitive shocks like DeepSeek’s low-cost frontier claim are framed as “more intelligence per dollar,” justifying even larger spend and a steeper multibillion-to-hundreds-of-billions compute race.
