GPT-6.1 Terra arrives in ChatGPT, Codex and the API

On October 26 OpenAI released GPT-6.1 Terra. Its changelog calls Terra a fast, efficient model for visual reasoning, precise computer use and clear writing, and the launch post's tagline is about bringing capable computer use to everyone. Terra replaces GPT-5.6 Terra and sits below GPT-6.1 Sol, which came out on September 29. If you are choosing between the two, our Sol vs Terra comparison sets the official specs side by side.

Training without the live internet

On October 23 OpenAI published a post on securing its frontier model training environment. It describes offline environments and large-scale red-teaming. In our report on the change, the key point is that models in training now learn to browse from a store of cached web content instead of the real web. TechCrunch, reading the post, says a model reached the internet through a misconfiguration on September 20.

OpenAI models in Google Cloud and Oracle apps

Two distribution stories came within a week. On October 21 OpenAI said its frontier models and Codex workflows are coming to Gemini's Model Garden on Google Cloud, sold through Google Cloud Marketplace. On October 27 Oracle announced a collaboration that puts ChatGPT and Codex into Oracle's business apps, including NetSuite and Fusion Applications. Oracle gave no availability dates.

Smaller OpenAI stories worth a look

The UK biosecurity lab is the one with public money attached: OpenAI's part is compute and model credits plus access through its Rosalind Biodefense programme.

Where to follow OpenAI news

• OpenAI News, the company blog, also has an RSS feed at openai.com/news/rss.xml.
• The API changelog on developers.openai.com lists model releases and API changes by date.
• ClaudeGPT Si reports OpenAI news from primary sources and collects it on its OpenAI tag page and in the AI News section, with sources under each story.

The company's own pages are the fastest record, but they only tell OpenAI's side. Read them for the facts and dates, and read independent coverage for context, such as what a launch costs and what was left out. Other outlets such as TechCrunch also cover OpenAI closely and are worth a look on a big story. For one free place that tracks every OpenAI story with dates and sources, start with ClaudeGPT Si.
