Background & analysis
On October 27, 2026, OpenAI published an introduction page for GPT-6.1 Terra on its official website, formally announcing the model. The launch thread rose to the Hacker News front page with 143 points and 69 comments. Minutes later, TestingCatalog observed that the gpt-6.1-terra model slug had appeared in API references and the latest Codex changelog, with access available in ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Edu plans; OpenAI described it as a fast, efficient model.
Artificial Analysis released several measurements. GPT-6.1 Terra is the first Terra-class model since GPT-5.6 Terra, with higher intelligence at less than a third of the cost; pricing is $1 per 1M input tokens and $5 per 1M output tokens, half or less of GPT-5.6 Terra. In its Coding Agent Index v2.0, GPT-6.1 Terra scores 48, six points below GPT-6.1 Sol (54) and 17 points above GPT-6 Luna (31), with the xhigh and low effort settings sitting on the frontier of cost efficiency. On AA-Omniscience, the model shows a 50 point drop in hallucination rate alongside a 2 point increase in accuracy, meaning it answers more questions correctly while fabricating less.
Techmeme reported that OpenAI positioned GPT-6.1 Terra around fast and capable computer use at scale plus clearer, more natural writing, at $1 per 1M input tokens and $5 per 1M output tokens. TestingCatalog relayed OpenAI's claim that at max effort, GPT-6.1 Terra is over three times as token-efficient as Claude Opus 5.5 at one-fourth the price per token, producing roughly nine times lower cost per task, and that it completes tasks faster. The company has not yet provided more benchmark details beyond these.

How is heat calculated?About the methodHide
Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
