Astra is the internal codename for OpenAI's next major language model (suspected successor to GPT-5), which has not yet been publicly released. OpenAI first announced Astra on August 1, 2026, by solving ten long-standing open mathematical problems. On September 1, 2026, OpenAI designated Astra as the first model to reach the "critical" cybersecurity threshold in its proprietary Preparedness Framework, resulting in heavily restricted access to advanced capabilities. OpenAI has not yet published official core specifications such as pricing, context window, license, or Benchmark values; a final release date remains pending.
