    OpenRouter 推出美国区域路由,与 EU 路由形成端到端数据驻留

    OpenRouter 在去年 10 月上线的 EU 路由之外新增美国 In-Region Routing,请求发往 us.openrouter.ai 后在美国境内解密,并只路由到美国境内的供应商端点,eu.openrouter.ai 对欧盟同理。API key、请求体和模型 ID 不变,供应商偏好、回退和隐私设置沿用账户配置;若区域内没有可服务该模型的供应商,请求会返回 404 而不会路由到区域外。该功能面向 Business 和 Enterprise 套餐,可用模型包括 GPT-5.6、Claude Opus 5、Gemini 3.6 Flash、Grok 4.6、DeepSeek V4 Pro、Kimi K3、GLM 5.2 等,GLM 5.2 也可在 EU 路由下由 Mistral 的欧盟数据中心提供。

    OpenAI 与 Anthropic 的集中度风险如何传导至 AI 产业

    Ed Zitron 认为,OpenAI 与 Anthropic 对少数客户和风险资本支持的 AI 初创公司高度依赖,并以巨额算力承诺将风险传导至云厂商与芯片公司。Ramp 数据显示,两家公司 80% 的企业收入来自 1% 的客户;文章还称其算力承诺合计超过 $1.3 Trillion,并将这种结构与金融危机前的高风险抵押贷款及利率重置压力相比较。

To estimate the contribution — and be incredibly fair! — I have assumed OpenAI and Anthropic’s Microsoft spend will be linear (at $52.5 billion) across fiscal year 2028, and then halved

    Charlie O’Neill 分析强化学习扩展下应如何构建训练环境

    Charlie O’Neill 认为,无论递归式自我改进能否实现,强化学习环境都应围绕长周期任务、真实用户需求和自身领域知识构建。他主张能力难以跨领域迁移,而有效推进任务的时长更可能泛化;相比少量合成的前沿难题,覆盖多领域和难度的真实数据可能更有价值。

    d this. Like, if you believe truly in the value of data, instead of doing mech interp, you’d probably just be building the environments to do mech interp. Similarly, on a somewhat meta point, if you believe in the value of RL environments, you should probably not be making RL environments, but indeed making RL environments to make RL environments. (I guess you would do this if you believed in RSI, and not otherwise.) Another perhaps non-obvious point to make is about how valuable different types
