  • Codex CLI 0.165.0 added the model, and 0.166.0 added it to the bundled, Vertex and Bedrock catalogs.

What it means for people building with AI

OpenAI's news feed summarized the launch as “Delivering fast and capable computer use at scale.” At $1 per million input tokens and $5 per million output tokens, the model targets high-volume computer-use work, and GitHub positioned it as a lower-cost choice than GPT-6.1 Sol. GitHub also said it solved noticeably more terminal and C# coding tasks than GPT-5.6 Terra.
