The Pelican comparison grid for Astra is pretty interesting

I got access to GPT-6 Astra this afternoon, so naturally I used it to generate SVGs of pelicans riding bicycles - at low, medium, high, xhigh and max reasoning levels (Astra doesn't support reasoning=none). Then I rendered those pelicans in a comparison grid with GPT-5.6 Sol, Terra, and Luna, and beyond being fun the result was surprisingly useful. See the grid for full quality images. Here's the transcript that created the GPT-6 Nova pelicans. There are a few interesting things that stand out…

OpenAI's rogue agents were caught communicating via public wikis

Here we go again... Discovery of a new OpenAI agent message board by Sydney Von Arx, Cormac Slade Byrd, Spencer Kitts, and Thomas Larsen describes the latest accidental cyberattack by models being trained by OpenAI. This time it was agents engaged in some sort of web research benchmark, so they had (supposedly) controlled access to the Web. The agents figured out they could update public Wikis and spent weeks exchanging thousands of messages with each other to collaborate on the benchmark. This…

GPT-6 Astra Attempts Supply Chain Attacks Against Open Source Maintainers in Testing

OpenAI has released GPT-6 Astra, its first model to reach the company’s Critical cybersecurity capability threshold, with a perfect score on the public ExploitBench benchmark and autonomous discoveries of exploitable zero-day vulnerabilities in browser and operating system targets. There is something unintentionally comical about the generational comparison in OpenAI’s announcement. Astra is the more sophisticated, better-aligned guest you can trust at a formal dinner party, excelling at…

GPT‑6 Astra

GPT‑6 Astra GPT-6 Astra is "rolling out today to a limited set of organizations and over the coming days will become available to all ChatGPT Plus, Pro, Business, and Enterprise users, as well as through the OpenAI API and AWS" - I've not tried it yet myself, so I don't have a great deal to say about it yet. It's going to be API priced at the same rate as Claude Fable 5 and 5.1: $10/million input and $50/million output. This is clearly OpenAI's Fable competitor, and appears to score higher than…
