Joe Weisenthal: 我观察到市场出现了严重的低迷,许多科技公司的股价都出现了大幅下跌,其中Nvidia的跌幅最为显著,这似乎与DeepSeek的出现有关。 Tracy Alloway: 我也注意到市场低迷的程度,以至于需要用标准差来衡量。一些人甚至开始将这次下跌称为“健康的调整”,而不是崩盘。 Zvi Mowshowitz: DeepSeek V3的训练成本约为550万美元,这引发了人们对成本效益的关注。虽然DeepSeek的低训练成本令人印象深刻,但这并不意味着其他公司可以轻易复制其低成本模式。DeepSeek的低成本是建立在大量前期投入的基础上,包括数据获取、工程师招聘、集群构建和优化等,总成本远高于550万美元。DeepSeek由于受到芯片出口限制,不得不进行高效的芯片利用,从而降低了训练成本。DeepSeek开源的背后是其背后的团队相信AI应该共享,并促进全球AI生态系统的发展。开源越来越强大的AI模型具有潜在的风险,因为人工智能通用智能(AGI)可能带来无法预测的风险。DeepSeek对OpenAI构成了直接威胁,因为它提供了一个更便宜、更有效的推理模型。Anthropic由于缺乏计算能力,其发展可能受到DeepSeek的影响。Meta的Llama模型受到了DeepSeek的严重冲击,因为DeepSeek的性能更好,且无需依赖Llama。长期来看,专门的推理芯片将会出现,但Nvidia目前在该领域占据主导地位。DeepSeek的出现并没有减少对计算能力的需求,反而因为推理计算的增加,导致对GPU的需求持续增长。大型语言模型领域的竞争激烈,主要原因是:1. 数据来源相似;2. 各公司都在快速扩展规模;3. 技术相对容易复制。

Chapters
The introduction of DeepSeek, a cheap Chinese AI model, caused a significant market downturn. Despite its relatively low training cost of \$5.5 million, DeepSeek's performance rivaled more expensive models due to clever optimizations and efficient use of resources. However, the overall cost including infrastructure and engineering reached hundreds of millions.
  • DeepSeek's low training cost of $5.5 million (V3) belied its high performance.
  • DeepSeek's success stemmed from efficient optimizations and resource usage, not just low cost.
  • The total cost of developing DeepSeek involved hundreds of millions of dollars in infrastructure and engineering.

Shownotes Transcript

On Monday, the stock market tanked, seemingly in reaction to the emergence of DeepSeek, an open source AI model developed in China. Nvidia, the semiconductor giant that has been the largest winner of the AI boom, erased $589 billion in market cap, for the biggest one-day wipeout in US stock-market history). Other chipmakers and big tech giants also swooned. So how did DeepSeek do it? Is it a big threat to the American AI giants like OpenAI and Anthropic? What does this say about export restrictions on US chips? On this special emergency session of the podcast, we spoke with Zvi Mowshowitz, an AI expert who authors the excellent Substack, Don’t Worry About the Vase. He answered all our questions and more to help understand what it means.
