OpenAI has started rolling out GPT-6 Astra to $20-a-month ChatGPT Plus subscribers after initially limiting the model to select organizations and higher-tier plans.. Astra launched on Sept. 3 and was later expanded to Pro, Enterprise and Business Premium users through ChatGPT Work and Codex before reaching Plus users over the recent weekend..
OpenAI said in a post on X that it “might take a few days to roll out to our Plus and Business users.” Free-tier users have no announced access.. Astra’s main feature is computer use, which lets the model navigate software, browse the web and operate programs on a user’s behalf without requiring an API..
OpenAI cofounder Greg Brockman said in a press briefing that computer use “has crossed the qualitative threshold” and described it as “very accurate, efficient, and reliable.”. Demonstrations have shown Astra researching topics online, writing scripts and operating 3D modeling software such as Blender autonomously..
OpenAI has called Astra “the most intelligent and aligned model in the world” and positioned it as a full version jump from GPT-5.6 Sol. On benchmarks, Astra scored 99.9% on ARC-AGI-3 in its memory-retaining Adapter Harness mode, compared with 7.8% for GPT-5.6 and 30.2% for Anthropic’s Claude Opus 5..
The model also scored 98% on FrontierMath Tier 4 and 100% on ExploitBench, a cybersecurity benchmark that tests whether a model can develop working exploits from known vulnerabilities.. That ExploitBench result led OpenAI to classify Astra as its first model at the “critical” level for cybersecurity risk and to gate the rollout of its most sensitive capabilities..
Astra is also available through the OpenAI API, Microsoft Azure and Amazon Bedrock at $10 per million input tokens and $50 per million output tokens, about 2.5 times the cost of GPT-5.6 Sol.. The launch has drawn mixed reactions. The Chosun Ilbo reported that ARC Prize benchmark results indicate memory retention, rather than model size alone, drives performance..
Some Blender users and other creatives criticized an OpenAI marketing video that showed a user delegating 3D modeling and game development to Astra.. The artist behind Blender 5.2’s splash screen said she felt “disgust” after seeing her work appear in the advertisement.. Early testers said Astra can still hallucinate and ignore instructions, prompting doubts about claims that the model is close to artificial general intelligence..
