[新聞] 告別GPU OpenAI推出極速晶圓引擎模型

原文標題： Introducing OpenAI GPT-5.3-Codex-Spark Powered by Cerebras 原文連結： https://www.cerebras.ai/blog/openai-codexspark 發布時間： 2026-02-12 記者署名： James Wang 原文內容： Today, we’re announcing that OpenAI’s new GPT-5.3-Codex-Spark model, powered b y Cerebras, is available in research preview. This marks the first release in ou r collaboration between Cerebras and OpenAI. Codex-Spark is designed for real-ti me software development where responsiveness matters as much as intelligence. Po wered by the Cerebras Wafer-Scale Engine, it runs at over 1,000 tokens/s, enabli ng near-instant feedback in live coding environments. 今日，我們正式發布由 Cerebras 技術驅動的 OpenAI 全新模型 GPT-5.3-Codex-Spark，並 開放研究預覽。這是 OpenAI 與 Cerebras 合作的首個里程碑。Codex-Spark 專為對響應速 度要求極高的即時軟體開發而設計。憑藉 Cerebras 晶圓級引擎（Wafer-Scale Engine）的 強大效能，其執行速度突破每秒 1,000 個標記（tokens/s），為即時程式開發環境提供近 乎瞬時的回饋。 Agentic coding has fundamentally changed software development. For the first tim e, machines can autonomously work for hours or days without human supervision. B ut this mode of interaction can also leave developers feeling out of the loop wi th long wait times and less opportunity to direct the work. As software developm ent is iterative, developers need to inject taste, direction, and sensibility al ong the way. Codex-Spark is designed for this kind of real-time, iterative work. It is fast, responsive, and steerable, putting the developer back in the driver ’s seat. Codex-Spark is a smaller version of Codex optimized for fast inference. On agent ic software engineering benchmarks such as SWE-Bench Pro and Terminal-Bench 2.0, it produces more capable responses than GPT-5.1-Codex-mini while completing tas ks in a fraction of the time. Codex-Spark excels at making precise edits, revising plans, and answering contex tual questions about your codebase. It’s a fast way to visualize new layouts, r efine styling, and test new interface changes. 「代理型編碼」（Agentic coding）已從根本上改變了軟體開發，使機器能獨立運作數小時 甚至數日。然而，這種模式也可能讓開發者因漫長的等待而產生疏離感，減少了引導工作的 機會。由於軟體開發本質上是反覆迭代的過程，開發者需要隨時注入審美、方向感與判斷力 。Codex-Spark 正是為此類即時、互動式工作而生；它反應迅速且易於引導，讓開發者重新 掌握主導權。 Codex-Spark 是針對快速推論（Inference）優化的 Codex 精簡版本。在 SWE-Bench Pro 與 Terminal-Bench 2.0 等代理型軟體工程基準測試中，它的表現優於 GPT-5.1-Codex-min i，且完成任務的時間僅需後者的一小部分。 Codex-Spark 擅長進行精確編輯、修訂計畫，以及回答關於程式碼庫的脈絡問題。對於視覺 化新佈局、精煉樣式及測試介面更動，它提供了一種極速的實現方式。 "Cerebras has been a great engineering partner, and we’re excited about adding fast inference as a new platform capability. Bringing wafer-scale compute into p roduction gives us a new way to keep Codex responsive for latency-sensitive work , and we’re excited to learn from developer feedback on how to compose our comp ute capabilities into one smooth workflow," said Sachin Katti, Head of Industria l Compute at OpenAI. OpenAI 工業運算負責人 Sachin Katti 表示：「Cerebras 是傑出的工程合作夥伴，我們很 高興將『快速推論』納入平台能力。將晶圓級運算導入生產環境，為維持 Codex 在延遲敏 感型任務中的響應速度提供了全新途徑。我們期待透過開發者的回饋，學習如何將這些運算 能力整合進流暢的工作流中。」 Codex-Spark is just a taste of what’s possible on Cerebras hardware. Our broade r goal is to accelerate a wide spectrum of AI workloads across both real-time an d asynchronous use cases. Our purpose-built Wafer-Scale Engine features the larg est on-chip memory of any AI processor, enabling high-speed inference at thousan ds of tokens per second per user. The architecture scales out to thousands of sy stems, extending fast memory capacity into the multi-terabyte domain to support trillion-parameter models for both training and inference. We expect to bring th is ultra-fast inference capability to the largest frontier models in 2026. Codex-Spark is rolling out as a research preview for ChatGPT Pro users across th e Codex app, CLI, and VS Code extension, with API access rolling out to select d esign partners.
