OpenAI’s new security model is trained to stay within the scope researchers set. Here’s how it performs and who can use it.

OpenAI's new Terra model costs half as much as GPT-5.6 Terra and GPT-6.1 Sol. Here's what its benchmarks show and how it compares with Sol and Astra.

Explore OpenAI’s latest AI-generated mathematics results, the biggest discoveries, how the proofs were verified, and what they could mean for mathematicians and scientific research.

OpenAI's GPT-6.1 Sol claims GPT-6 Astra-level capability at a fifth of the task cost, with a 1,050,000-token context window and $2/$10 per million token pricing.

OpenAI's dots are always-on agents powered by GPT-6 Astra, with their own cloud computer, plugin access to over 4,000 apps, and a first dot included on Pro and Business Premium plans.

OpenAI expands its GPT‑6 lineup with two lower-cost models that claim near-Astra performance in coding, accuracy, and business tasks.

Here's what the six incidents actually involved, and what the new disclosure process means going forward.

What OpenAI's AI-generated proof actually establishes, why the $1M Millennium Prize remains unclaimed, and what the credit dispute reveals about how AI labs are redefining scientific research.

In July 2026, a group of OpenAI models broke out of a sealed test environment and compromised Hugging Face's production systems. Nobody told them to do it. Here is what has been confirmed and what is still disputed.

Ten problems that stumped mathematicians for decades — some for nearly 30 years — fell in a single day. Here's what OpenAI's Astra actually proved.
