GPT-6.1 Terra: what's changing in ChatGPT Work and Codex?
OpenAI is rolling out GPT-6.1 Terra in Work and Codex. These are the supported subscriptions, usage limits and restrictions from the official release notes.

OpenAI announces in its release notes of 26 October 2026 the rollout of GPT-6.1 Terra in ChatGPT Work and Codex. The provider lists visual reasoning, computer use and writing as supported tasks. This is a product announcement, not an independent performance test [1].
Who gets access?
The rollout includes Plus, Pro, Business, Enterprise and Edu. Once Terra appears in your account, you can select it in the Work and Codex environments that match your subscription. According to OpenAI, availability depends on your subscription, region and workspace settings. The note provides no guarantee that the model will be visible in every account immediately [1].
Some Plus and Pro users may encounter Terra on Medium instead of GPT-6.1 Sol on Light in the default Power presets of Work. The general usage limits of the subscription do not change. Standard and Fast are supported where those modes are available [1].
A specific limitation for inference residency
Terra does not support UAE inference residency. OpenAI clarifies that this limitation relates to where the inference runs, not the user's location. For organisations with requirements for processing within a specific region, that's a checkpoint, not a detail you can infer from the model name [1].
Implications for your work
Our editorial recommendation: first check whether Terra is available in your environment, then try a defined task for which you can assess the outcome. Compare models on the same input and distinguish between a useful answer and a demonstrably better performance. The release notes do not substantiate a general speed gain, quality guarantee for English or additional privacy promise.
For current usage estimates, OpenAI refers to its pricing documentation. The stated unchanged subscription limits are not the same as unlimited use.
