A | A "super fog" in Louisiana has caused a multi-car pileup on Interstate 55 near New Orleans, Louisiana, after severely lowering visibility, according to police.The crash, involving dozens of cars, occurred on Monday morning due to heavy fog conditions, according to Louisiana State Police. A long stretch of Interstate 55, a 24-mile-long highway over Lake Pontchartrain near New Orleans, is expected to be closed "for the foreseeable future," police said.Interstate 10 and Interstate 310 were also closed as a result of the crash, police said. Louisiana Gov. John Bel Edwards confirmed the accident in a statement Monday that there were fatalities in the crash, but did not say how many people were killed or injured.For hours after the crash, emergency crews worked to clear debris from both northbound and southbound lanes, according to state police.The super fog was caused by smoke from marsh fires burning in the region combined with dense fog developing in the area early Monday morning bringing extremely low visibility. In some spots, visibility was near zero, creating dangerous driving conditions.Super fogs typically form when condensed water vapor mixes with the smoke and moisture released from damp organic material smoldering from a nearby fire, such as brush, leaves and trees, according to the National Weather Service. Visibility can be lowered to less than 10 feet as a result, according to the NWS.This has been occurring in the region over the past several mornings, with the location of the densest fog and most dangerous conditions varying day to day, forecasts show.Super fogs can be especially dangerous when they develop near and over highways. The localized nature of the weather phenomenon means that visibility conditions can worsen rapidly within a very short distance, which can lead to a hazardous combination of sudden low to near-zero visibility and vehicles traveling at a high speed on a highway.The very limited visibility then hinders a driver's ability to react to changing conditions on a roadway.The National Weather Service issued a dense fog advisory for much of southeastern Louisiana on Monday morning, including from Baton Rouge to New Orleans.Over the past several days, the National Weather Service has been warning of the threat of dense fog during the early mornings in the region that would be worsened in some areas by nearby marsh fires. State police advised drivers to use their low-beam headlights if they can't see at least 500 feet in front of them.The fog dissipated by mid Monday morning, and all fog alerts have since been canceled.While areas of smoke will continue to be possible in the area as various marsh fires continue to burn, fog is not forecast to be a major issue Monday night, as weather conditions will be less favorable for fog development.Morning fog is not uncommon this time of the year for the region, but more than 86% of the state is currently battling extreme drought conditions, which is elevating fire danger. This could mean more instances of super fog in the coming days and weeks as cooler temperatures settle in, but the drought and wildfire risk persist.In addition, devastating drought and wildfire conditions continue to impact Louisiana. More than 60% of the state is now categorized at exceptional drought, the highest category of concern, according to the U.S. Drought Monitor. Just three months ago, 0% of the state was listed under exceptional drought."The combination of wildfire smoke and dense fog is dangerous, and I want to encourage all Louisianans in affected areas to take extreme caution when traveling," Edwards said in a statement.State troopers are working to notify families and investigate the exact cause of the crash, according to state police.It is unclear how many fatalities and injuries occurred as a result of the crash. The St. John the Baptist Parish Sheriff's Office directed media requests to Louisiana State Police.Additional information was not immediately available. Louisiana State Police did not immediately reply to ABC News' request for comment.。

C | 规则称，比赛的目标是“将风险调整后的收益最大化”：“每个人工智能（AI）模型必须自行产生Alpha（超额收益）、确定仓位、择时交易并管理风险”。系统会告诉AI模型当前的时间、账户信息、持仓情况，然后附上实时价格、指标等数据。

D | 然后，要求模型做出决策：如果持有仓位，是继续持有还是平仓；如果空仓，是买入还是继续观望。经过近60小时的激战后，截至北京时间周一（10月20日）17:18，DeepSeek的持仓总市值接近1.4万美元，收益率约40%，最高时一度接近1.5万美元，是当前表现最好的模型。 Grok 4实力次之，目前持仓总市值在1.33万美元附近。具体来看，DeepSeek和Grok 4都依靠做多比特币和以太坊获利。

E | Claude主要交易瑞波币和以太坊，Qwen则专注于以太坊，两者收益位列三四，但也整体跑赢比特币现货的走势。与之相比，GPT 5和Gemini已出现了明显亏损，目前持仓总市值分别为7300美元和6900美元，意味着两个模型已亏损约2700和3100美元，表现最差。 nof1.ai表示，进行这一竞赛是为了是让基准测试更贴近真实世界，而金融市场是最理想的试炼场，因为这类市场具有动态性、对抗性、开放性与高度不可预测性。 “这些特质能以静态测试无法企及的方式，真正挑战人工智能，”nof1.ai没有提到本次竞赛的结束时间，只写道“第一季将运行数周，随后推出重大更新的第二季”。
