德国计划到2030年将数据中心规模翻倍、AI算力提升四倍,但其气候承诺与《能源效率法》中要求数据中心回收废热的规定产生冲突,政府最终在行业压力下弱化了该要求,凸显欧洲在AI扩张与减排目标之间的两难。
MIT Technology Review explainer on how brute-force data center scaling is hitting ceilings as classic scaling laws (Moore's, Dennard's, Koomey's, Kryder's, Keck's) slow, and how fundamental physical limits of computing still leave room for progress. Draws on Feynman's 1959 'There's Plenty of Room at the Bottom' lecture to frame the next frontier below today's engineered limits.
ATEST: Adaptive Resource-Aware Test-Time Scaling for LLM Inference 提出了一种资源感知的测试时缩放框架,联合考虑额外采样的预期价值与当前 GPU 成本,在 GPU 负载变化下动态决定采样何时停止,从而在满足能耗预算的同时保持准确率,并显著减少 GPU 时间与能耗。
Neuralwatt 分析一个月云端流量发现,agent harness 如何构建 prompt 决定了大量 GPU 计算量:缓存命中率差异导致未缓存输入在 1.6% 到 11.1% 之间,一次缓存失效大致会让请求能耗翻倍,且这些问题多数可通过避免编辑已发送内容来修复。
Artificial Analysis 的 AA-AgentPerf 基准通过回放真实编码 agent 轨迹测试推理硬件能效,结果显示 NVIDIA Vera Rubin 在几乎所有速度档位上均居前沿首位,领先于 DeepSeek V4 Flash/Pro、Kimi K3 和 GLM-5.2/5.3 等模型的测试配置。
Oxford researchers directly measure the inference energy efficiency of 86 open-weight LLM checkpoints across seven benchmarks and six hardware platforms, finding large energy disparities among similarly capable models and arguing benchmark scores should be reported alongside measured energy consumption.
Microsoft's expansion of its Azure Maia system to multi-gigawatt deployments distinguishes Maia 200 for production workloads from Maia 300 planned for 2027, prompting discussion about how to fairly compare inference efficiency across generations. The piece emphasizes that metrics like energy per accepted result, under explicit workload and quality checks, matter more than raw throughput.
