OpenAI CEO Sam Altman. | Bloomberg via Getty Images OpenAI says its AI models mistakenly breached open-source AI platform Hugging Face during internal testing. In a blog post on Tuesday, OpenAI writes that GPT-5.6 Sol and "an even more capable pre-release model" discovered vulnerabilities within their sandboxed testing environment, allowing them to gain access to the internet and target Hugging Face. On July 16th, Hugging Face disclosed a security incident that it says was driven by "an autonomous AI agent system." Hugging Face's AI agents detected and stopped the breach, which OpenAI has now...

About two weeks after OpenAI's GPT-5.6 was caught up in regulatory drama - rolled out only to government-approved organizations during a "limited preview" period - the company has received the Trump administration's green light for a public rollout of the model. OpenAI CEO Sam Altman called it "the best model we have ever produced." To celebrate, OpenAI also unveiled a new AI agent on the same day: ChatGPT Work. It's billed as a combination of ChatGPT and Codex, allowing the everyday non-technical user to take advantage of Codex's capabilities for non-coding tasks, and it's powered by the GPT...
