OpenAI releases GPT-6.1 Terra for high-volume computer work
The benchmark results, including 50.3% on Terminal-Bench 4.0 at maximum effort, and the fall in error rate on OpenAI's internal benchmark are OpenAI's own evaluations, not independent reruns. Per-token prices do not show the cost of a finished task, which depends on effort settings, retries and accepted outputs.
What was claimed?
OpenAI released GPT-6.1 Terra, a fast model for visual reasoning, computer use and writing. It is available to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, and in the API as gpt-6.1-terra at $1 per million input tokens, $0.05 per million cached input tokens and $5 per million output tokens, which OpenAI says is 50% below GPT-5.6 Terra and GPT-6.1 Sol.
What does the evidence support?
Company claim, independent confirmation unresolved
Cheaper models that can operate desktop software make routine office automation, such as entering invoice details into accounting software, less costly to try. OpenAI says the model meets the Critical cybersecurity threshold in its Preparedness Framework and keeps the protections built for GPT-6 Astra.
What are the limits?
The benchmark results, including 50.3% on Terminal-Bench 4.0 at maximum effort, and the fall in error rate on OpenAI's internal benchmark are OpenAI's own evaluations, not independent reruns. Per-token prices do not show the cost of a finished task, which depends on effort settings, retries and accepted outputs.
