Meta高管否认Llama 4分数造假
Meta生成AI副总裁否认了公司为提高新模型Llama 4在特定基准测试中的表现而进行调整的传言，称其“根本不属实”。他明确指出，公司并未在测试集上训练模型以抬高分数。
该传言源自社交媒体，声称Meta人为提高了Llama 4 Maverick和Scout模型的基准测试结果。有报告称这些模型在某些任务上表现不佳，以及Meta使用未发布版本在LM Arena获得高分，助长了此猜测。
Meta高管承认，不同云服务商托管的模型质量存在差异，表示模型刚发布，需要几天时间进行调整。公司将继续修复错误并与合作伙伴协作。

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
