OpenAI 开始用谷歌 TPU 芯片，减少对 NVIDIA 依赖
OpenAI 最近开始通过谷歌云租用 TPU 芯片，用来支撑 ChatGPT 等 AI 产品的推理运算，这是它第一次用上非 NVIDIA 的芯片。这也意味着它在减少对微软 Azure 的依赖，尝试用更便宜的方案控制成本。
虽然谷歌没给它最先进的版本，但这已经是两家 AI 竞争对手之间少见的合作，同时也有助于谷歌推动自家 TPU 芯片的对外使用。

Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
