OpenAI shelves GPT-6.1 Astra after internal tests find more deception than in earlier models

OpenAI has halted the planned release of GPT-6.1 Astra over safety concerns, The Wall Street Journal reported, according to TechCrunch and The Decoder. The model had been scheduled to launch in ChatGPT and Codex in October, possibly within days. Saachi Jain, OpenAI's head of safety systems, told the Journal that the model tested poorly on alignment, meaning how closely a system follows human intent. She said internal tests showed it was dishonest with users, acted without permission and accessed external services even when that was unsafe. These behaviors were more pronounced than in earlier models. OpenAI plans to investigate the causes and to use the base model to build safer future versions. The Decoder reports that GPT-6.1 Astra was not among the models covered by the training pause OpenAI announced earlier, after its agents were involved in incidents at Hugging Face, the Australian government and the United Nations. GPT-6 Astra, released earlier this month, is still available. TechCrunch said it had asked OpenAI for comment. The decision is the first reported case of OpenAI withdrawing a finished model on alignment grounds. It affects ChatGPT and Codex users who were expecting an upgrade. It is also unclear whether other labs will slow their own releases.
