螞蟻百靈大模型今日開源萬億參數旗艦模型Ling-2.6-1T，採用MLA與LinearAttention混合架構實現“快思考”機制，提升智效比，在評測中展現高Token效率，解決真實生產流中的效率難題。
OpenAI於4月26日宣佈終止專用編程模型Codex獨立分支，將其核心能力整合至GPT-5.5主模型。自GPT-5.4起，專用編程分支消失，GPT-5.3成爲最後一款獨立Codex模型。此舉標誌OpenAI迴歸“通用主義”策略，用單一強力系統覆蓋包括編程在內的所有專業場景。
小米發佈MiMo-V2.5系列大模型，包含MiMo-V2.5、V2.5-Pro及配套TTS與ASR模型，標誌着模型從“能用”到“好用”的升級。其中旗艦型號MiMo-V2.5-Pro在通用智能體能力和軟件工程方面已能與Claude Opus4.6、GPT-5.4等頂尖模型競爭，核心優勢在於高指令遵循度和自我修正能力。
OpenAI擴大網絡防禦計劃，向全球安全專家開放專用模型GPT-5.4-Cyber，被視爲對Anthropic Claude Mythos的迴應。該模型針對防禦場景優化，支持二進制逆向分析，幫助專家分析惡意軟件，提升網絡安全防護能力。
