國產大模型參數規模持續攀升，Qwen3.8Max、Kimi K3已分別達2.4萬億和2.8萬億。字節跳動計劃訓練超5萬億參數模型，有望成爲國內最大，但項目尚處早期，未必發佈。5萬億參數被視爲GPT-5.6或Opus5級別，標誌着能力進一步躍升。
Claude Opus5模型展現強大的代碼生成能力，開發者用同一條提示詞讓其直接生成射擊、潛艇、賽車及沙盒等多款遊戲。整個過程無需任何外部素材，模型可直接輸出幾何結構、紋理、物理效果與音樂，全部在瀏覽器中運行，顛覆傳統依賴資源庫的遊戲開發模式。
Anthropic旗艦模型Claude Opus5剛上線，其完整系統提示詞就被開發者Eversmile1泄露在GitHub上，包括網頁端和手機端的底層提示詞。全文共135027字符、19370英文詞，約3.4萬token，內容詳盡無遮掩，令Anthropic措手不及。
