奥特曼发布OpenAI新模型GPT-6.1 Terra：主打电脑操作、API每百万输入词元1美元
OpenAI首席执行官奥特曼（Sam Altman）10月26日在社交平台X上宣布推出新模型 GPT-6.1 Terra，并写道：「6.1 Terra来了！它擅长很多事情，但我们尤其为这个电脑操作的新时代感到兴奋。」OpenAI随后正式发布该模型，将其定位为 GPT-6 家族中价格更低的一档，专门面向「电脑操作」类任务：模型可以直接与电脑屏幕交互，完成填写表单、处理发票、剪辑视频和解读技术图纸等工作。财经媒体 Benzinga 于10月27日报道了此次发布。OpenAI总部位于旧金山，奥特曼自2019年起担任该公司首席执行官，是GPT系列模型历次发布的主要宣布者。
据OpenAI公布的数据，GPT-6.1 Terra 完成任务的速度比 GPT-6 Astra 与 GPT-6.1 Sol 快三倍以上；公司内部测试显示，在低推理强度下，该模型处理困难提示的错误率为16.7%，低于上一代 GPT-5.6 Terra 的53.6%。OpenAI同时说明，上述结果来自公司自有评测、未经独立验证。公司还称，新模型更善于守住任务边界、识别障碍，并能抵御提示注入攻击；但对于最复杂的编程任务，GPT-6.1 Sol 与 GPT-6 Astra 仍是更好的选择。
价格与开放范围方面，开发者通过 API 使用 GPT-6.1 Terra 的价格为每百万输入词元1美元、每百万输出词元5美元，为 GPT-6.1 Sol 标价的一半；单个请求输入超过27.2万词元时，整单将按更高价格计费。该模型现已通过 ChatGPT Work 与 Codex 向 Plus、Pro、Enterprise 和 Edu 订阅用户开放。OpenAI建议开发者在把现有工作负载迁移到新模型之前，先用自身任务进行测试。在 GPT-6 家族中，Sol 与 Astra 此前已分别覆盖高难度编程与通用任务，Terra 的加入使该家族在电脑操作类智能体任务上补齐了低价档位。
Sam Altman Unveils OpenAI's GPT-6.1 Terra for Computer Use, Priced at $1 per Million Input Tokens
OpenAI Chief Executive Sam Altman on October 26 announced the launch of GPT-6.1 Terra on X, writing: "6.1 Terra is here! It is good at a lot of things, but we are especially excited for this new era of computer use." OpenAI then formally released the model, positioning it as the lower-cost tier of the GPT-6 family built for computer-use tasks: the model can interact directly with computer screens to fill out forms, process invoices, edit videos and interpret technical drawings. Benzinga reported the launch on October 27.
According to OpenAI, GPT-6.1 Terra completes tasks more than three times faster than GPT-6 Astra and GPT-6.1 Sol. The company's internal testing showed an error rate of 16.7% on difficult prompts at low reasoning effort, down from 53.6% for GPT-5.6 Terra; OpenAI noted the results come from its own evaluations and have not been independently verified. The company said the model is also better at staying within task boundaries, identifying obstacles and resisting prompt-injection attempts, while for the most complex coding tasks GPT-6.1 Sol and GPT-6 Astra remain the better choice.
For developers, GPT-6.1 Terra costs $1 per million input tokens and $5 per million output tokens through the API, half the listed rates for GPT-6.1 Sol, with higher pricing applying to requests exceeding 272,000 input tokens. The model is now available to Plus, Pro, Enterprise and Edu subscribers through ChatGPT Work and Codex. OpenAI recommends that developers test Terra on their existing workloads before migrating applications.
