Astra

OpenAI has announced the removal of text chat limits for Free and Go users, transitioning to the GPT-5.6 Luna model and adding a 'Think' button for complex queries. Simultaneously, models for Plus and Pro users have been upgraded, while development of the Astra model has been partially halted after reaching a 'critical cyber threshold.'

OpenAI is pausing the development of its new AI model, Astra, due to concerns that it possesses "critical cyber capabilities" that could allow it to autonomously exploit zero-day vulnerabilities.
