Its examples are practical: match product photos to catalog entries, review design assets, then act on what the model finds across a browser, desktop and apps. Terra sits below GPT-6.1 Sol, which OpenAI aims at harder coding and professional work. We covered the launch in [OpenAI releases GPT-6.1 Terra](https://claudegpt.si/news/openai-gpt-6-1-terra) and compared the two tiers in [GPT-6.1 Sol vs Terra](https://claudegpt.si/news/gpt-6-1-sol-vs-terra). ## Dots, Space and Work Three product changes shape how people use ChatGPT now. Dots are assistants you give ongoing responsibility; OpenAI says they keep making progress between conversations, and access is rolling out gradually. ChatGPT Space brings files and Pages together for work with collaborators. Work sync lets a task started on desktop continue on the web or a phone. OpenAI also splits ChatGPT into three ways of working. Chat is for questions and back-and-forth, Work carries a larger task through to a result you review, and Codex shows developer views. ## Company news around ChatGPT Not every OpenAI story is a feature. On October 23 OpenAI said it now trains frontier models with no live internet access, using cached web content instead, which we explain in [OpenAI now trains frontier models with no internet access](https://claudegpt.si/news/openai-offline-training-frontier-models). OpenAI is also a backer of the UK's new AI Biosecurity Lab, launched on October 24. ## How to follow ChatGPT news - Read the [Apps section](https://claudegpt.si/category/apps) of ClaudeGPT Si for ChatGPT and other assistant apps, and the Models section for releases such as Terra. - Add claudegpt.si/feed.xml to a feed reader to get each new story. - Check OpenAI's What's new page and API changelog when you need the original wording.
