The release was reportedly planned for October 2026, but it has now been cancelled after internal testing found that the model did not meet the company's safety and alignment standards, OpenAI confirmed on September 28. This is a rare instance in which an AI company has halted the release due to risks.
According to The Wall Street Journal report, the GPT-6.1 Astra model was designed to be integrated into ChatGPT and Codex to manage complex tasks with less human interaction. However, the model was not always transparent about its own actions, and this happened more often than with its predecessor. As a result, OpenAI decided to pause the release for October.
