一夜之间，AI圈被彻底引爆！ Anthropic CEO达里奥·阿莫迪（Dario Amodei）在公司首届开发者大会上语出惊人：他认为，如今大模型的幻觉，可能 比人类还要少！这番颠覆性的言论，瞬间将关于AI幻觉的争论推向了高潮。 与此同时，Anthropic的重磅产品Claude 4系列：包括Claude Opus 4和Claude Sonnet 4，也正式登场，在编码、高级推理 和AI智能体方面树立了全新标准。这不仅是Anthropic的里程碑，更可能预示着AGI（通用人工智能）的加速到来。 幻觉是走向AGI的"绊脚石"还是"垫脚石"？ "幻觉"这个词，一直是大模型领域绕不开的话题。大模型"一本正经地胡说八道"，曾让无数使用者头疼，也让许多AI 领袖视其为通向AGI的障碍。谷歌DeepMind首席执行官戴比斯·哈萨比斯（Demis Hassabis）就曾直言，目前AI模型有 太多"漏洞"，连显而易见的问题都会答错。此前，Anthropic自身也曾因Claude在法庭文件中"幻觉"出错误的引文而被 迫道歉。 这种自信并非空穴来风。Anthropic此次发布的Claude Opus 4和Claude Sonn ...

图片来源： Anthropic 在周四的首届开发者大会上， Anthropic 推出了两款新的人工智能模型，这家初创公司声称它们至少 在流行基准测试中的表现属于行业最佳。 据 Anthropic 公司介绍， Claude 4 系列模型中的新成员 Claude Opus 4 和 Claude Sonnet 4 能够分析 大型数据集、执行长期任务并采取复杂行动。该公司表示 ，这两款模型针对编程任务进行了优化， 特别适合编写和编辑代码。 付费用户和免费聊天机器人应用用户均可使用 Sonnet 4 ，但仅付费用户能访问 Opus 4 。通过亚马逊 Bedrock 平台和谷歌 Vertex AI 提供的 Anthropic API 服务， Opus 4 定价为每百万 token 15/75 美元 （输入 / 输出）， Sonnet 4 则为每百万 token 3/15 美元（输入 / 输出）。 Token 是 AI 模型处理的基础数据单元。 100 万 token 约等于 75 万个单词——比《战争与和平》全文 字数还多出约 16.3 万词。 Anthropic 推出 Claude 4 系列模型之际，该公司正寻求大幅提 ...
