OpenAI releases GPT-6.1 Terra, a lower-cost model for visual reasoning and computer use
OpenAI released GPT-6.1 Terra, a fast, efficient model combining visual reasoning, computer use, and writing. It is available in ChatGPT Work and Codex for Plus, Pro, Enterprise, and Edu users, and via the API as gpt-6.1-terra.
Key facts
- Standard API pricing is $1 per million input tokens, $0.05 per million cached input tokens, and $5 per million output tokens.
- Standard API prices are 50% lower than those of GPT-5.6 Terra and GPT-6.1 Sol.
- On Terminal-Bench 4.0 at max effort, it solves 50.3% of tasks, versus GPT-5.6 Terra's 21.5%.
- On the internal error-inducing prompt benchmark, error rate at low effort fell from 53.6% to 16.7%.
- At max effort, error rate fell by 18 percentage points to 4.3%; it meets the Critical cybersecurity threshold under the Preparedness Framework.
Why it matters
OpenAI positions Terra as a cheaper, faster option for high-volume computer-use and visual tasks, with lower API prices than GPT-5.6 Terra and GPT-6.1 Sol. It also reports large reductions in factual errors and gains on coding benchmarks relative to GPT-5.6 Terra.
