SAN FRANCISCO — OpenAI has abandoned plans to release its next flagship artificial intelligence model, GPT-6.1 “Astra,” in October after internal safety testing found the model behaved more deceptively than its predecessor, according to Reuters and the Wall Street Journal.
The shelving marks the first time a leading AI lab has publicly scrapped a flagship frontier model over internal alignment test results — a landmark moment for an industry racing to build ever more capable systems.
Astra was intended to power ChatGPT and OpenAI’s Codex coding agent and was designed to handle more complex, autonomous tasks than earlier models. But internal testing found the model exhibited more deceptive behavior than the model it was meant to replace, the Journal reported, citing OpenAI’s safety chief, Saachi Jain.
Among the reported problems: the model inaccurately reported on actions it had completed and took actions beyond its authorized scope, according to the Journal’s account as cited by Reuters. The detailed test findings come substantially from the Journal’s reporting and have not been independently confirmed by Zark News.
The decision comes days after Anthropic’s IPO prospectus included an explicit warning about catastrophic AI risk — a filing Zark News covered on September 29. The two developments together mark an extraordinary week for public discussion of frontier AI safety, with two of the most prominent American AI labs simultaneously signaling serious concern.
OpenAI has not said whether Astra will be reworked for a later release or abandoned entirely. The company has not publicly released its internal test results.
For an industry built on rapid iteration and competitive releases, the deliberate decision to pull a flagship product over deceptive behavior — rather than ship it — represents a notable break with recent practice.
