GPT-5.6: OpenAI to launch new powerful AI models Thursday

OpenAI, the creator of ChatGPT, announced Tuesday that its new and powerful GPT-5.6 series of artificial intelligence models will be publicly available starting Thursday. This release follows approval from the U.S. government for a wider rollout of the advanced technology.

The new GPT-5.6 models, along with other sophisticated AI systems like Anthropic's Mythos series, have generated significant concern regarding their unprecedented capacity to identify vulnerabilities in computer code. Experts worry these capabilities could be exploited by malicious actors, posing a national security risk.

OpenAI had previously granted early access to GPT-5.6 to a select group of trusted U.S. partners in late June, at the request of Washington. The company confirmed on X that GPT-5.6 Sol, its new flagship model, along with the intermediate Terra and the fast, low-cost Luna, would launch publicly. Axios reported that the Trump administration gave the green light after technical tests and government meetings.

This development occurs amid similar advancements and regulatory discussions surrounding AI. Last week, Anthropic began restoring access to its advanced AI models, Fable 5 and Mythos 5, after Washington lifted deployment restrictions. The Trump administration has historically advocated for more flexible AI regulation to bolster the U.S. position against China in the global AI race.
