OpenAI released GPT-6 Astra on Thursday, claiming it surpasses Anthropic's best models.
It is the first to cross a critical cybersecurity threshold.
The rollout is limited to businesses initially to address vulnerabilities.
What happened
OpenAI began a phased release of GPT-6 Astra on Thursday, its newest model. The company says it surpasses Anthropic's most advanced models and meaningfully approximates artificial general intelligence.
Why it matters
GPT-6 Astra is OpenAI's first model to cross the critical cybersecurity capability threshold, so it will be initially limited to businesses to allow them to address vulnerabilities. The move echoes Anthropic's restricted release of Mythos, whose capabilities prompted regulatory scrutiny — the Pentagon affirmed its ban of Mythos on the same day.
What to watch
Two US lawmakers on Thursday introduced the first, largely symbolic legislation to pause AI development. OpenAI is striving to regain the initiative in the AI race amid growing anxiety from experts, tech leaders, and the public over frontier AI risks.

The rollout comes as OpenAI faces pressure to stay ahead in the AI race while managing rising concerns about frontier AI risks. The Pentagon's affirmation of its ban on Anthropic's Mythos the same day highlights the regulatory sensitivity around advanced models.
The limitation to businesses initially is a practical step to mitigate potential misuse. The largely symbolic legislation to pause AI development underscores the political dimension, though its impact is unclear as it is described as symbolic. Overall, GPT-6 Astra's release marks a significant milestone in capability, but also signals a new phase of caution in how such models are deployed.
