智譜開源原生多模態模型GLM-5.3-Flash（320B-A18B），以領先性能和極致定價推動AI普惠。該模型測評獲57分，與Claude Opus4.8持平，編程能力相當，綜合性能超越GLM-5.2。發佈前以匿名“Ox-Alpha”公開測試，登頂OpenCode、OpenRouter平臺調用。
AI服務商Writer推出旗艦模型Palmyra X6，基於開源模型GLM-5.2後訓練變體，並升級智能代理運行框架，可將企業基礎任務的Token成本降低高達50%，旨在破解AI“越用越貴”困境。
智譜發佈大模型GLM-5.3，參數量仍爲7400多億，與GLM-5.2同底，未升級萬億參數（或留待5.5）。其依靠後訓練使性能較上代提升50%，在多項主流基準中居開源模型榜首，編程與智能體能力接近Claude Fable5，編程體驗優於其他國產模型。
智譜發佈GLM-5.3，基座模型完全未變，提升全部來自後訓練Scaling。通過數十倍規模長程任務環境、更豐富環境類型和超長後訓練時間，相同基座智能上界被顯著擡高。內部評測編程體感較GLM-5.2提升約50%，成爲當前編程能力最強的開源模型，公開基準表現同樣亮眼。
