Simon Willison's report quotes the launch description, which lists tasks including proposal drafting, interpretation of technical drawings, form filling, and video editing.
The reported API price is $1 per million input tokens and $5 per million output tokens. Willison describes that as almost half the price of GPT-5.6 Terra and GPT-6.1 Sol, and about ten times the price of GPT-6 Luna. In a Hacker News comment quoted by Willison, OpenAI's Ted Sanders says Terra is faster for vision and computer-use work, stronger than Luna for those uses, and cheaper than Sol.
The source does not provide independent benchmark results, context-window details, availability terms, or reliability measurements for computer-control tasks. It also does not establish that Terra is the best choice outside the described vision, computer-use, and communication workloads.
