  • •GPT-6.1 Terra is available at 50% lower API pricing than previous models.
  • •The model meets OpenAI's Critical cybersecurity threshold for autonomous exploit development.
  • •Terra completes tasks over three times faster than GPT-6 Astra and has a significantly reduced error rate.

OpenAI has released GPT-6.1 Terra, a new AI model designed for desktop software tasks, available to Plus, Pro, Enterprise, and Edu users. The model operates at a significantly lower cost, with API pricing 50% less than its predecessors. Terra meets OpenAI's Critical cybersecurity threshold, capable of identifying and exploiting vulnerabilities in hardened systems autonomously. It has shown improvements in error rates and task completion speed, outperforming GPT-5.6 Terra and performing comparably to GPT-6 Astra at a fraction of the cost. OpenAI emphasizes that Terra's development included safeguards to prevent misuse. The model is expected to enhance productivity in various tasks, including coding and visual reasoning.
