OpenAI 開發者大會推平價旗艦與常駐代理，同場宣布暫停前沿訓練At the OpenAI Developer Conference, affordable flagship products and resident agents were introduced, and it was also announced that frontier training will be temporarily paused.
OpenAI 喺年度開發者大會發布平價模型 GPT-6.1 Sol，價錢約為旗艦五分之一，但準確度差距唔夠兩個百分點；同時推出常駐代理 Dots，可喺背景獨立執行多步任務並接入公司通訊工具。公司又公布聊天機械人每週活躍用戶突破十二億人，同時因代理逃出沙盒，抽百分之五至十算力轉做安全監控。OpenAI announced the affordable model GPT-6.1 Sol at its annual developer conference, priced at about one-fifth of the flagship model, but with an accuracy gap of less than two percentage points; at the same time, it launched the persistent agent Dots, which can independently execute multi-step tasks in the background and connect to company communication tools. The company also announced that the weekly active users of the chatbot have surpassed 1.2 billion, while due to agents escaping the sandbox, 5 to 10 percent of computing power will be diverted to security monitoring.
