OpenAI Says GPT-6 Astra Is 'The Most Intelligent And Aligned Model In The World'

A little under two months after releasing its last major model family to the public, GPT-5.6 Sol, Terra and Luna, OpenAI is back with an entirely new one: GPT-6 Astra, what it claims is "the most intelligent and aligned model in the world." Following the company's decision to slow frontier model development in August after one of its models hacked AI platform Hugging Face, it may also be the last major AI model it releases for a while.

GPT-6 Astra excels at computer-use and browsing, and handling tasks in the domains of software engineering, cybersecurity, science and general professional work, according to OpenAI. A flashy demo video the company released alongside the launch shows Astra handling everything from 3D modeling to building slideshows, and often taking care of multiple tasks across different domains at the same time (like ordering food while coding a game). Key to Astra's appeal is its ability to handle these multi-step workflows on your computer and in and out of your browser. It's also allegedly able to do those complex tasks with "strong visual judgment," OpenAI says, and without drifting from its original directions or prompt.

As with other model launches, the company has a new tranche of benchmarks to justify Astra's improved abilities, including a 98.6% score on ARC-AGI-3, one of the industry's benchmarks for measuring an AI's ability to solve unfamiliar problems. VentureBeat notes that the score has some caveats, namely that AIs that have been put through the benchmark aren't all configured in the same way, and different system architecture (like whether they have persistent memory, for example) can produce different results. Other improvements are more clear-cut: Astra scored 57.7% on Terminal Bench 4.0, a coding benchmark, and 59.3% on the Agent's Last Exam, a benchmark for measuring an AI's agentic capabilities, notably higher than GPT-5.6 Sol. OpenAI included even more benchmarks in its announcement, but in short, Astra is now at the top of most leaderboards in terms of performance.
