国产大模型参数规模持续攀升，Qwen3.8Max、Kimi K3已分别达2.4万亿和2.8万亿。字节跳动计划训练超5万亿参数模型，有望成为国内最大，但项目尚处早期，未必发布。5万亿参数被视为GPT-5.6或Opus5级别，标志着能力进一步跃升。
Claude Opus5模型展现强大的代码生成能力，开发者用同一条提示词让其直接生成射击、潜艇、赛车及沙盒等多款游戏。整个过程无需任何外部素材，模型可直接输出几何结构、纹理、物理效果与音乐，全部在浏览器中运行，颠覆传统依赖资源库的游戏开发模式。
Anthropic旗舰模型Claude Opus5刚上线，其完整系统提示词就被开发者Eversmile1泄露在GitHub上，包括网页端和手机端的底层提示词。全文共135027字符、19370英文词，约3.4万token，内容详尽无遮掩，令Anthropic措手不及。
