ChatGPT maker OpenAI said its latest powerful artificial intelligence model series will be released to the public on Thursday, as the U.S. government reportedly approved a broader launch.
The company's new GPT-5.6 offerings and other cutting-edge AI models, including Anthropic's Mythos series, have drawn concern over their supposedly unprecedented ability to identify weaknesses in code that hackers can exploit.
That has raised national security fears, and OpenAI said in late June it had shared preview access to GPT-5.6 with a limited group of trusted U.S.-based partners at Washington's request.
Large language models are the technology that underpins chatbots and many other AI tools, with their capacity to crunch through colossal amounts of digital data.
The GPT-5.6 series has three tiers: Sol, the company's new flagship model; Terra, a mid-range version for everyday work; and Luna, a fast, low-cost option.
