Apple has officially unveiled its integrated enterprise tools suite, now referred to as Apple Business, which takes the place of the former Apple Business Essentials. This updated platform is designed to improve organizational capabilities and streamline user interactions.

### Business Essentials has transitioned to Apple Business

Apple Business 2.0 brings a revamped design and enhanced features, featuring a new Liquid Glass app icon. A notable addition is the directory feature, which enables users to quickly find and connect with colleagues, thus facilitating communication and collaboration within organizations.

### Support for Apple Vision Pro

For the very first time, the Apple Business app is compatible with Apple Vision Pro, broadening its functionality across various devices. The app works seamlessly on iPhone, iPad, and Mac, ensuring it is accessible to a diverse range of users.

Apple Business 2.0 is ready for download on the App Store, offering businesses a comprehensive set of tools to boost productivity and connectivity. For additional information, visit the [Apple Business website](https://www.apple.com/business/).

OpenAI has revealed a new AI model named GPT-5.4-Cyber. Comparable to Anthropic’s Claude Mythos, this latest “cyber-permissive” iteration of its GPT-5.4 is designed for defensive cybersecurity and is not intended for public usage.

## OpenAI’s Latest Variant Aims to Set the Stage for More Advanced Models Ahead

OpenAI asserts that its new GPT-5.4-Cyber variant of GPT-5.4 is tailored to set the groundwork for more advanced models expected later this year.

> “To prepare for increasingly advanced models from OpenAI over the coming months, we are refining our models specifically for defensive cybersecurity applications, beginning today with a variant of GPT‑5.4 designed to be cyber-permissive: GPT‑5.4‑Cyber.”

Access to GPT-5.4-Cyber is restricted to “the highest tier” of users who can verify their status as cybersecurity defenders.

## Authorized Access for Cyber is Necessary for Employing GPT-5.4-Cyber

OpenAI clarifies that GPT-5.4-Cyber is “deliberately fine-tuned for enhanced cyber capabilities and with fewer restrictions on capabilities.”

> “This is a version of GPT‑5.4 that reduces the refusal threshold for legitimate cybersecurity tasks and enables new features for sophisticated defensive workflows, including binary reverse engineering capabilities that allow security experts to scrutinize compiled software for malware risks, vulnerabilities, and security strength without requiring access to its source code.”

Due to its more permissive design, the model will first be released in a limited, iterative manner to approved security vendors, organizations, and researchers. This deployment is part of an expanded version of Trusted Access for Cyber, a cybersecurity initiative initiated by OpenAI earlier this year. The company emphasizes two avenues for obtaining access to Trusted Access for Cyber.

OpenAI has also recently launched a new version of its Pro plan targeted at Codex users.
