OpenAI postpones GPT-6.1 Astra launch after safety testing

GPT-6.1 Astra was scheduled for launch in October 2026, but OpenAI has decided to abandon the model’s rollout. According to Wired en Español, the company’s research and safety teams detected weaker alignment with user values and goals compared to previous systems, and on this basis decided not to release it.

The news is corroborated by multiple independent sources: besides Wired en Español, ANSA also reported on the matter, dating its own report to September 29, 2026, and attributing the news to a Wall Street Journal investigation. OpenAI itself, in an official statement, declares that the planned larger frontier reinforcement training run remains on hold, while smaller-scale training and evaluations continue.

The decision marks a setback for one of the company’s most anticipated models, at a time when the generative artificial intelligence sector is under growing scrutiny over the risks tied to the safety and behavior of the most advanced systems. The fact that the decision concerns not only the single model but also the pause of an entire larger-scale training phase points to a caution that goes beyond the postponement of a specific product: the company is choosing to slow down an entire development track rather than make corrections on the fly to a single release.

It remains to be seen how long this pause will last and what corrections will be applied before a new launch window. Based on the available material, it is not possible to know a new date for GPT-6.1 Astra nor the technical details of the deviations detected in alignment testing. What remains established, confirmed by three distinct sources, is the suspension itself: the postponement of the model and the pause of frontier training.
