style=\"font-size: large;\">美股投资网获悉，OpenAI正式发布首款基于半导体初创公司Cerebras Systems Inc.芯片的人工智能模型，标志着ChatGPT开发商正主动扩大芯片供应商版图，以打破英伟达(NVDA)的独家供应格局。\u003C\u002Fspan>\u003C\u002Fp>\r\n\u003Cp>\u003Cspan style=\"font-size: large;\">该模型名为GPT-5.3-Codex-Spark，是编程自动化工具Codex家族的最新成员，定位为算力消耗更低但响应速度更快的轻量版本。该版本定于周四上线，支持软件工程师快速完成代码片段编辑、测试运行等任务。用户可随时中断进程或下达新指令，无需等待冗长的计算周期。\u003C\u002Fspan>\u003C\u002Fp>\r\n\u003Cp>\u003Cspan style=\"font-size: large;\">上个月，OpenAI与Cerebras敲定价值超100亿美元的硬件采购协议，以换取更快的模型推理响应。对Cerebras而言，这笔交易是其在英伟达长期垄断的市场上撕开缺口的关键一役。对OpenAI而言，这则是为满足指数级增长的算力需求而持续扩容供应商的最新落子。\u003C\u002Fspan>\u003C\u002Fp>\r\n\u003Cp>\u003Cspan style=\"font-size: large;\">去年10月，OpenAI与英伟达另一劲敌AMD(AMD)达成重磅合作，计划在未来数年内部署总容量达6吉瓦的AMD图形处理器。同月，OpenAI还敲定向博通(AVGO)定制芯片及网络组件的协议。近期，OpenAI与英伟达的关系因双方关系紧张的报道而备受关注，两家公司的首席执行官随后公开表态仍将保持紧密协作。\u003C\u002Fspan>\u003C\u002Fp>\r\n\u003Cp>\u003Cspan style=\"font-size: large;\">OpenAI发言人周四在声明中强调，与英伟达的合作是“基石性”的，旗下最强AI模型正是双方“多年软硬件协同工程的产物”。“正因如此，我们将英伟达作为训练与推理架构的核心，同时通过与Cerebras、AMD、博通的合作，有意识地在核心之外拓展生态系统。”\u003C\u002Fspan>\u003C\u002Fp>\r\n\u003Cp>\u003Cspan style=\"font-size: large;\">全新Codex模型也是OpenAI与谷歌、Anthropic等劲敌在AI编程助手这一高增长赛道上争夺主导权的最新动作。OpenAI透露，Codex目前周活跃用户已突破100万。\u003C\u002Fspan>\u003C\u002Fp>\r\n\u003Cp>\u003Cspan style=\"font-size:
