蚂蚁百灵大模型今日开源万亿参数旗舰模型Ling-2.6-1T，采用MLA与LinearAttention混合架构实现“快思考”机制，提升智效比，在评测中展现高Token效率，解决真实生产流中的效率难题。
OpenAI于4月26日宣布终止专用编程模型Codex独立分支，将其核心能力整合至GPT-5.5主模型。自GPT-5.4起，专用编程分支消失，GPT-5.3成为最后一款独立Codex模型。此举标志OpenAI回归“通用主义”策略，用单一强力系统覆盖包括编程在内的所有专业场景。
小米发布MiMo-V2.5系列大模型，包含MiMo-V2.5、V2.5-Pro及配套TTS与ASR模型，标志着模型从“能用”到“好用”的升级。其中旗舰型号MiMo-V2.5-Pro在通用智能体能力和软件工程方面已能与Claude Opus4.6、GPT-5.4等顶尖模型竞争，核心优势在于高指令遵循度和自我修正能力。
OpenAI扩大网络防御计划，向全球安全专家开放专用模型GPT-5.4-Cyber，被视为对Anthropic Claude Mythos的回应。该模型针对防御场景优化，支持二进制逆向分析，帮助专家分析恶意软件，提升网络安全防护能力。
