2. Gemini 初期灾难性的 PR 至今依然在拖后腿。We don't get a second chance at first impressions. 时至今日大家还是言及 LLM 必提 ChatGPT 和 Claude，在开源语境下可能还会提到 Llama，当然现在得多个 DeepSeek。而 Gemini 很多时候甚至都不配出现在比较对象中…… 要知道最近几个发布比如 Gemini 2.0 Flash Thinking 的表现和成本都非常亮眼（见题图，出处 https://x.com/swyx/status/1882933368444309723）。
3. Stratechery 的解读一如既往地到位。如果没有订阅，这篇 [DeepSeek FAQ](https://stratechery.com/2025/deepseek-faq/) 是免费阅读的，推荐；如果订阅了，最近的几篇分析里对 OpenAI 的批评我认为说得很在点上。尤其关于 OpenAI （或者说 Sam 本人）对通过 regulation 巩固地位的渴望以及 o1 选择隐藏 chain of thought 的失误。
4. Reasoning 看起来潜力无限，相关从业者需要好好 reflect 自己的 research/product roadmap；而对 user 来说，一个或许有用的 tip 是从常规 model 换到 reasoning model 时，prompt 写得越像论文，得到的回答质量越好。In other words, reasoning models are not necessarily good chat models; and you might be disappointed if you use them like chat models.

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
