MiniMax M2.1正式發佈，這是一款專爲真實編碼和AI組織設計的先進開源模型。它擁有100億激活量，在SWE-multilingual測試中得分72.5%，在VIBE-bench測試中高達88.6%，性能超越Gemini3Pro和Claude4.5Sonnet等閉源模型，標誌着代理時代的重要進展。
快手KAT-Coder-Pro V1模型在Artificial Analysis評測中表現突出，以64分超越Claude4.5Sonnet，躋身總榜前十。在Non-Reasoning Model榜單中更以顯著優勢奪冠。該模型不僅性能卓越，且輸出Token消耗量遠低於同類模型，展現出高效能優勢。
AI基準平臺Epoch AI短暫出現代號“Claude Kayak”的新模型條目，標註今日發佈後迅速刪除，引發全球關注。業內普遍認爲這是Anthropic即將推出的旗艦模型Claude Opus4.5。作爲Claude4系列最強版本，預計在複雜推理、多步任務及代碼生成能力上實現大幅提升，有望在SWE-bench等評測中突破80%得分，直接對標OpenAI GPT-5.1與Google Gemini3。
谷歌發佈Gemini3，首次提供100萬tokens上下文窗口，原生支持文本、圖像、視頻與代碼多模態推理。Gemini3 Pro在GPQA測試獲91.9%準確率，LMArena以1501分超越GPT-5.1與Claude4.5登頂。採用Deep Think推理模式，通過“思維簽名”產品化推理鏈，在邏輯、事實與科學推理方面表現突出。
