Poolside發佈完全開源的Laguna S2.1大模型，118B總參數的MoE架構，每token激活8B，支持高達1M tokens上下文，適配長週期軟件工程。在OpenCode平臺免費開放，並引入thinking與no-thinking推理模式，引起開發者熱議。
前OpenAI CTO Mira Murati創立的Thinking Machines Lab於2026年7月15日發佈首個開源模型Inkling。該模型採用混合專家架構，總參數量達9750億，單次任務僅激活部分參數，實現高效定製。此舉意在挑戰巨頭主導的閉源AI模式，提供可高度定製的開放權重方案。
OpenAI發佈GPT-5.4模型，實現推理、編程與智能體工作流統一。新增“思維”模式，AI在回答前展示思考計劃，用戶可實時介入調整。同時增強深度搜索能力。
OpenAI發佈GPT-5.1，標誌AI競賽進入"情商融合"新階段。模型重點強化情緒價值、個性化交互與人性化表達，解決用戶反饋的"AI冰冷"問題。採用雙模型架構：Instant模式快速響應，Thinking模式深度思考。全球分批推送中，付費用戶3個月內可繼續使用GPT-5過渡。
