OpenAI最快模型GPT-5.3-Codex-Spark發佈僅7個月即下週退役。它每秒1200 token，是首個脫離英偉達、由Cerebras 750兆瓦大單交付的模型，但用量持續下滑，且已有更優替代。負責人稱需爲未來讓路，並吐槽模型名過長。
OpenAI與Cerebras合作推出GPT-5.3-Codex-Spark模型，專爲實時編程優化，解決AI編程中的“等待焦慮”。該模型利用Cerebras晶圓級引擎實現超高速推理，速度突破1000tokens/s，實現代碼生成與思緒同步的即時反饋。
OpenAI加速推進“去英偉達化”戰略，於2026年2月12日發佈首款基於Cerebras芯片的AI模型GPT-5.3-Codex-Spark。該模型專爲軟件工程師設計，提供更靈活的交互體驗，支持即時中斷與切換，使開發者能隨時暫停冗長計算，快速處理其他緊急編碼任務。
