B | BILLINGS, Mont. -- A Montana man has been sentenced to 18 months in federal prison for making repeated threatening and racist phone calls to a Billings church for two years after he went there seeking help and received a gift card from a Black employee, prosecutors said.Joshua Leon Hiestand, 41, was sentenced Friday, according to the U.S. Attorney’s Office in Montana. Hiestand pleaded guilty in June to making harassing telephone calls. A stalking charge was dismissed as part of the plea agreement.“When Hiestand, a white man, went to a Billings church looking for help, an elderly African American woman who worked there responded with kindness and assistance," U.S. Attorney Jesse Laslovich said in a statement. "In return and for nearly two years, Hiestand launched a barrage of harassing, hateful and racist calls and voicemails at her and the church. His racist conduct isn't just abhorrent, it is illegal.”Prosecutors alleged Hiestand went to the Presbyterian church in November 2020 seeking help. Five days later, the church received a voicemail in which someone, using a racially derogatory term, said he would give more money to the church if the church did not employ an African American. After three similar calls, the woman called Billings police.A detective called the number used to leave the messages and spoke to Hiestand, who admitted making the calls and apologized for his behavior, prosecutors said. He was told to have no further contact with the church. Three days later, he left a voicemail with the church in which he apologized, court records said.However, over the next 19 months Hiestand called and left a series of voicemails at the church that were at times threatening and racially hostile, prosecutors said. Investigators determined that after January 2021, Hiestand was placing the calls from outside the state of Montana.Hiestand was arrested in November 2022 in Indiana and has remained in custody since then.Hiestand’s public defender Gillian Gosch asked for a sentence of time served, arguing her client's actions were affected by his mental health issues, which have resulted in psychiatric hospitalizations and which appear to be worsened by his use of illegal substances.The Bureau of Prisons will decide whether Hiestand will receive credit for the 11 months he has already been in custody, officials said.Hiestand remained in custody in the Yellowstone County jail on Monday.。
C | 此次实测直接调用开源模型DeepSeek V4 Pro（1.6万亿参数），运行真实智能体编码任务，结果令人震惊。 在SemiAnalysis旗下AgentX基准测试中，Vera Rubin NVL72的每兆瓦吞吐量，比当前主力机皇GB300 NVL72最高飙升30倍，生产每百万Token的成本最高暴降35倍。 作为对比，GB300的每兆瓦吞吐量相较上代H200也已提升15倍，Vera Rubin是在这个基础上再拔高30倍。 英伟达借此宣告旧基准作废：传统8K或1K固定序列测试已无法衡量智能体，必须回放含上下文增长与工具调用的真实工作流。数据显示，一次Agent任务消耗的Token是普通聊天的15倍，长上下文成为关键瓶颈。 性能跃升来自极致协同设计。NVFP4量化将权重压至4位精度，第六代NVLink配合大模型MoE提供比以太网快10倍、延迟低3倍的互联，让DeepSeek这类专家模型在72颗GPU间行云流水调度。 同场还有两枚新芯量产：一是专为低延迟定制的Groq 3 LPX让Gemma 4 31B跑出每秒3400 Token；二是面向智能体打造的Vera CPU，含88个自研Olympus核心、内存带宽1.2TB/s。 值得一提的是Vera CPU已被马斯克SpaceXAI连夜装机，准备部署上太空。
