OpenAI Launches GPT-6.1 Terra AI Model for Enhanced Productivity

On October 26, 2026, OpenAI announced the release of GPT-6.1 Terra, a new AI model that promises enhanced efficiency in everyday work tasks. This model is part of the GPT-6 series and is designed to excel in computer use, visual reasoning, and natural writing. GPT-6.1 Terra represents a significant advancement over its predecessor, GPT-5.6 Terra, outperforming it in various benchmarks, including a notable 15 percentage points increase in performance on the Agents’ Last Exam. This benchmark evaluates the ability to tackle professional tasks such as converting architectural drawings into 3D models and reviewing films for restoration purposes.

In addition to improving task performance, GPT-6.1 Terra reduces costs associated with its use. The standard API pricing for this model is 50% lower than that of GPT-5.6 Terra and GPT-6.1 Sol, making it more accessible for developers looking to automate high-volume work. The model's capabilities extend to tasks like drafting proposals, interpreting technical drawings, and editing videos, thereby enhancing productivity across various industries. Furthermore, GPT-6.1 Terra significantly reduces factual errors, or hallucinations, that have historically challenged AI models. The error rate for low reasoning effort prompts dropped from 53.6% with GPT-5.6 Terra to 16.7% with GPT-6.1 Terra. At maximum reasoning effort, the error rate decreased to 4.3%, nearly matching the performance of more advanced models like GPT-6 Astra and GPT-6.1 Sol.

This improvement in factual accuracy is crucial for users relying on AI for precise information and decision-making. The model also excels in software engineering tasks, demonstrating more than double the success rate compared to GPT-5.6 Terra when solving coding problems from the command line. For scientific research tasks, GPT-6.1 Terra performs competitively at a lower cost, approaching the efficacy of leading models while remaining budget-friendly. These advancements reflect OpenAI's commitment to creating powerful AI tools that are both efficient and reliable.

As GPT-6.1 Terra becomes available to all Plus, Pro, Enterprise, and Edu users in ChatGPT Work and Codex, it is expected to play a pivotal role in transforming how individuals and organizations approach their work. OpenAI continues to focus on enhancing safety and alignment in its AI models, ensuring that users can trust the system to remain within scope and effectively communicate limitations. The introduction of GPT-6.1 Terra marks a new chapter in AI development, offering users a robust tool for improving productivity and achieving their goals.
