OpenAI 发布 GPT-6.1 Terra，主打视觉推理与电脑操作
GPT-6.1 Terra
OpenAI 发布 GPT-6.1 Terra，官方强调其详细视觉推理、精确电脑操作和更清晰自然的写作能力，定位为比 GPT-5.6 Terra 明显升级的快速高效模型。该模型在 Anthropic 模型序列中与 Sonnet 位置相当，既不是最便宜也不是最贵。OpenAI 的 Ted Sanders 在 Hacker News 评论中表示，Terra 在技术沟通上优于 Astra 和 Sol，视觉与电脑操作能力相近但速度快得多，其他多数方面略弱。价格方面，GPT-6.1 Terra 为每百万输入 token 1 美元、每百万输出 token 5 美元，约为 GPT-5.6 Terra 和 GPT-6.1 Sol 的一半，约为 GPT-6 Luna 的 10 倍。作者还展示了各推理档位的 pelican 测试图，其中 max 档耗时 4 分 11 秒、花费 11.3161 美分。

It's always interesting to note which aspects of a new model are emphasized in the release announcement.
In the case of GPT-6.1 Terra, OpenAI went with visual reasoning and computer use:
We’re introducing GPT-6.1 Terra, a fast, efficient model that combines detailed visual reasoning and precise computer use alongside clearer, more natural writing. A significant step up from GPT‑5.6 Terra, it excels at the communication and computer-based tasks that fill the workday, from drafting proposals and interpreting technical drawings to filling out forms and editing videos.
Terra sits in the same position as Sonnet in the Anthropic model collection - not the cheapest or the most expensive, making it harder to decide when to use it.
Computer use is a good example of a task that benefits from a less expensive model, since you might put it to work on automated, repetitive tasks.
OpenAI's Ted Sanders provided some useful advice in a comment on Hacker News:
In the case of GPT-6.1 Terra, I'd say Terra is probably better than Astra and Sol at technical communication, similar on vision and computer use (but much faster!), and a bit worse on most other things. For API developers, it's a nice midrange option if you want something cheaper than Sol but a lot smarter than Luna (especially for vision / computer use / communication). For subscribers, it's not a bombshell release - if you're hitting usage limits, maybe it helps you go a bit further, and if you want clearer communication or faster computer use, it can be a nice option to select.
Here are the pelicans for the different reasoning levels. This pelican for "max" cost 11.3161 cents and took 4 minutes and 11 seconds:
Here's a new comparison grid showing pelicans for every reasoning level of OpenAI's current frontier lineup: GPT-6 Astra, GPT-6.1 Sol, GPT-6.1 Terra, and GPT-6 Luna.
GPT-6.1 Terra is priced at $1/million input tokens and $5/million output - almost half the price of GPT-5.6 Terra and GPT-6.1 Sol, and around 10x the price of GPT-6 Luna.
