OpenAI is rolling out GPT-6.1 Terra, a new artificial intelligence (AI) model that costs half as much as two of its other models and is practical for automating high-volume work such as reading invoices and entering their information into accounting software, the company said in a Monday (Oct. 26) press release.
GPT-6.1 Terra is “a significant step up” from GPT-5.6 Terra, while its standard application programming interface (API) prices are 50% lower than those of GPT-5.6 Terra and GPT-6.1 Sol, according to the release.
Along with automating high-volume work, GPT-6.1 Terra excels in communication and computer-based tasks, including drafting proposals, interpreting technical drawings, filling out forms and editing videos, the release said.

OpenAI made GPT-6.1 Terra available to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, and to developers through the OpenAI API, on Monday, per the release.
“Terra continues to advance the cost-intelligence frontier across our model families, providing a new balance of speed, capability and cost,” OpenAI said in the release.
Bloomberg reported Oct. 9 that OpenAI’s enterprise business is driving the company’s gains in annualized revenue, which is expected to reach at least $70 billion by the end of the year, up from $50 billion at the end of September.
When OpenAI began rolling out ChatGPT Work on July 9, the company described the product as a new agent that is designed for work that is more complex than a typical chat request. OpenAI said ChatGPT Work can take action across the user’s apps and files; can spend hours on a project, if needed; and can produce sheets, slides, docs, web apps and other finished materials.
OpenAI announced in July that it made changes to improve its models’ performance per dollar across enterprise workloads. The company cut the price of GPT-5.6 Luna by 80%, cut the price of GPT-5.6 Terra by 20% and provided faster performance of GPT-5.6 Sol in the API while leaving its price unchanged.
“The GPT-5.6 family expands the range of those choices,” OpenAI said at the time in a blog post, referring to the ability of users to select the right model for the outcome they seek. “Businesses can apply the maximum useful intelligence at every stage while paying the right price for the value it creates.”
