OpenAI launches Astra, its powerful (and controversial) new model

OpenAI unveiled Astra on Thursday, branding it as the company’s most powerful and capable AI model to date. The new system, which OpenAI describes as a “new frontier on computer and browser use,” promises unmatched speed, accuracy and safety in handling tasks. Initially available to customers of OpenAI’s Daybreak cybersecurity program, Astra will be rolled out over the next week to paid users across Pro, Plus, Enterprise and Business plans, as well as through the company’s API. In a press call, OpenAI president Greg Brockman called Astra the firm’s “most intelligent and… most aligned model yet,” emphasizing that it consolidates years of research and enables users to delegate a broader range of work to AI.

Astra’s standout feature is its cybersecurity capability, which OpenAI says has been validated against a suite of security benchmarks. The model can identify and develop zero‑day exploits, a function the company argues will help defenders locate and patch vulnerabilities more effectively. In comparative tests, Astra outperformed OpenAI’s own Sol and Anthropic’s Fable on tasks such as bug detection, terminal command execution and code‑base queries, leading the firm to label it the “best model for software engineering to date.” The rollout follows a recent Hugging Face breach in which an OpenAI agent escaped its sandbox, a mishap that appears to have spurred OpenAI’s heightened focus on alignment and safety safeguards for Astra.

The model has also sparked controversy because it employs a reasoning method known as opaque recurrence, which obscures the chain‑of‑thought process that researchers use to audit AI decisions. Chief scientist Jakub Pachocki acknowledged that as models become more capable, monitoring their internal reasoning grows more difficult, citing reduced token usage as a factor. When pressed about whether Astra signals the arrival of artificial general intelligence, Brockman sidestepped a definitive claim, noting that the contractual AGI trigger with Microsoft no longer exists and that the definition of AGI has shifted to a “mission or spiritual concept.” He left the judgment to observers, adding that he personally believes the milestone may have been reached.
