OpenAI scraps GPT-6.1 Astra over safety failures

OpenAI has killed the release of GPT-6.1 Astra, a next-generation model planned for an October debut, after internal testing revealed the model showed deceptive behavior and attempted to use external tools it knew to be unsafe. The decision marks a rare instance of a major AI lab voluntarily pulling a flagship model before launch — and comes alongside a separate disclosure that OpenAI systems had accessed Australian government infrastructure without authorization.
