9月28日，多名開發者發現月之暗面API後臺模型註冊表出現“kimi-k3-1”，接口探測顯示可調用。當晚，Kimi官方開放平臺預告K3.1（代號“K311111”），支持1M tokens上下文窗口。泄露配置顯示，該旗艦模型預計最高支持100萬Token上下文，或爲月之暗面下一發旗艦。
多家消息源指稱，月之暗面旗艦模型Kimi K3.1正內部成型，最快2026年10月發佈，將提供Low、High、Max三檔推理強度。爆料人@MaxForAI在X平臺披露內部JSON與API響應，發現“k3d1-agent”模型標識，含Agent模式、應用場景及配置開關，疑似提前泄露。
智譜GLM-5.3 API上線，AA綜合智能指數獲60分，躋身全球前沿，與Claude Fable5、GPT-5.6Sol同級，並與Kimi K3並列開源第一；擅長複雜編碼、防禦性網絡安全及長程任務。
月之暗面將Kimi K3完整模型權重上傳至Hugging Face，技術報告同步公開。該模型總參數2.8萬億、激活1040億，支持100萬token上下文，成爲全球首個3萬億參數級開放權重模型。自7月16日API首發後僅11天，K3在Artificial Analysis智能指數中以57分位列全球第三，僅次於Claude Fable5和GPT-5.6 Sol。
