GPT-6 Astra is officially here. OpenAI released its newest flagship model today, calling it a generational leap in capability and, according to president Greg Brockman, a possible arrival point for artificial general intelligence. “Welcome to the AGI era,” he said during the announcement. Here’s what actually shipped, what it costs, and what to expect as access widens over the coming days.

Astra is being positioned as OpenAI’s best model yet for computer use. That means it can navigate a browser, work inside a spreadsheet, move across different apps and websites, and carry out multi-step tasks the way a person would at a keyboard, rather than needing a custom integration built for every tool it touches. OpenAI’s launch materials describe it as capable of producing finished documents and presentations and completing full workflows on its own, calling it “the world’s best computer use model.”

The company also says Astra is state of the art across a wide range of areas, including software engineering, browser use, cybersecurity, and general professional work. On a coding benchmark called DeepSWE v1.1, which tests performance on complex tasks in real codebases, OpenAI reports Astra ranking ahead of both its own previous flagship, GPT-5.6 Sol, and Anthropic’s Fable 5.1. On FrontierMath Tier 4 v2, a demanding math benchmark, OpenAI reported a score of 97.6 percent, and on ARC-AGI-3, a benchmark built to test reasoning in unfamiliar interactive environments, the company reported 98.6 percent.

Those numbers come from OpenAI’s own testing and haven’t yet appeared on independent trackers like Artificial Analysis or Arena.ai, so expect a clearer, independently verified picture over the next few days as more people get hands on access.

One notable detail from this release is that Astra is the first OpenAI model to reach the company’s “Critical” threshold for cybersecurity capability under its internal Preparedness Framework. In practical terms, that means it’s able to find and chain together previously unknown vulnerabilities in well protected systems without a person guiding it step by step. During testing, OpenAI says the model identified two real zero day exploits, which were disclosed responsibly to the affected maintainers. Because of that capability jump, Astra’s most advanced cyber features are being rolled out first to vetted defenders inside OpenAI’s Daybreak program, with broader access following in phases.

For everyone else, the rollout looks like this. Astra is going first to organizations in the Daybreak program, then to ChatGPT Plus, Pro, Business, and Enterprise users, and then to the API and Amazon Web Services over the coming days. Standard Astra access is included within existing ChatGPT Plus allowances, while a higher end version called Astra Pro is reserved for Pro, Business, and Enterprise accounts. A free tier hasn’t been announced yet.

On pricing, once Astra is available through the API it will cost 10 dollars per million input tokens and 50 dollars per million output tokens. That’s roughly two and a half times what Sol currently costs at its promotional rate, and it lines up exactly with what Anthropic charges for its own top tier models, Fable 5.1 and Mythos 5.1, which were released just days earlier. OpenAI’s framing is that businesses should think less about the price per token and more about the price per completed task, since a model that finishes a job in fewer steps can end up costing less overall even at a higher rate per token.

Astra also supports Zero Data Retention for eligible API customers, and OpenAI says it’s testing a feature called Private Safety Processing alongside the release.

What is GPT-6 Astra?
It’s OpenAI’s newest and most capable model, built around strong computer use and agentic task completion, with reported gains in coding, math, and cybersecurity performance over the company’s previous flagship.

How much does GPT-6 Astra cost to use?
Through the API, it’s priced at 10 dollars per million input tokens and 50 dollars per million output tokens, matching Anthropic’s current top tier pricing.

Whether Astra ends up living up to the AGI framing is going to take more than a launch day to settle. What’s clear right now is that the model is real, it’s rolling out, and the numbers behind it are worth watching as independent testing catches up.
