阿里巴巴开源自主搜索 AI 智能体 WebAgent
阿里巴巴于5月30日在Github上开源其自主搜索AI Agent——WebAgent，该Agent具备端到端的自主信息检索与多步推理能力。WebAgent能够主动搜索学术数据库、筛选文献并进行分析总结。WebAgent包含WebDancer和WebWalker两部分，前者是端到端智能体训练框架，后者是“Web 遍历中的 LLM 基准测试”。WebDancer框架由数据构建、短/长推理、监督微调（SFT）和强化学习（RL）四个阶段组成，采用DAPO算法进行强化学习。WebAgent旨在增强基于网络的AI智能体的多步骤信息搜索能力。

Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazon’s servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as “the largest digital migration in human history.” Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
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.”
