28 Oct 2026GPT-6.1 Terra: a fast model in a crowded roomGPT-6.1 Terra landed on OpenAI's deployment safety hub on 26 October 2026 as an addendum to the GPT-6 Astra system card (https://deploymentsafety.openai.com/gpt-6-1-terra). It is the mid-tier model in the GPT-6 series. It sits below the Sol and Luna variants in capability, and above nothing, since the slot has been empty. I think it handles medium and small tasks "pretty decently" for my needs.↗28 Oct 2026When the Model Writes Your Own ExploitsI have built and run production systems for over thirty years. The part that keeps me up at night has moved. It used to be configuration drift, library rot, operator error. Those are all still there. But now a model can find a chain of five bugs across a browser sandbox, a kernel, and a payment library before you have finished your coffee.↗
