Quick answer: OpenAI launched GPT-6.1 Terra on October 26, 2026, a faster, cheaper model built for computer use, visual reasoning, coding and everyday work. OpenAI says it performs on par with GPT-6 Astra at about one-tenth the per-token price and completes tasks more than three times faster than GPT-6 Astra and GPT-6.1 Sol. API pricing is $1 per million input tokens and $5 per million output tokens.
What happened
OpenAI described Terra as “fast and capable computer use at a lower price.” The model understands what is on screen, takes action across apps and writes naturally, making it suited to tasks such as filling in forms, editing videos, reading technical drawings and automating repetitive desktop work.
Benchmarks
- Agents’ Last Exam: 15 percentage points higher than GPT-5.6 Terra at medium reasoning effort, at about one-third the cost.
- Error rate (internal): Fell from 53.6% to 16.7% at low effort, and to 4.3% at maximum effort, close to GPT-6 Astra and GPT-6.1 Sol.
- Terminal-Bench 4.0: 50.3% at max effort, more than double GPT-5.6 Terra’s 21.5%.
Pricing and availability
GPT-6.1 Terra costs $1 per million input tokens and $5 per million output tokens, 50% less than GPT-5.6 Terra and GPT-6.1 Sol. It is rolling out to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, and developers can use it in the API as gpt-6.1-terra. OpenAI still recommends GPT-6.1 Sol or GPT-6 Astra for the most complex coding tasks.
Why it matters
Terra continues a sharp price war among AI labs. Commentators noted OpenAI and Anthropic have cut LLM prices by up to 80% within a few months. Cheaper, faster agent models make it more practical to automate workflows such as content operations, SEO audits, reporting and data entry, and they make AI agents browsing the web more common, which affects how sites are crawled and used.
