Meta新AI模型“Maverick”涉嫌优化“作弊”，引发业内质疑
Meta近日发布的新旗舰AI模型“Maverick”在LM Arena排行榜上名列第二，但研究人员指出，该测试版本与开发者可用的公开版本存在明显差异。
Meta承认，参与测试的是“针对对话优化”的实验性版本。研究者发现，LM Arena上的Maverick回答更冗长，使用大量表情符号，而公开版本则表现平平。此举引发业内对AI公司是否应为排行榜优化模型的争议。过度定制测试版本可能误导开发者，破坏评测公正性。Meta与LM Arena官方目前尚未回应相关质疑。

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
