Now Apple is focus is focusing on enhancing its own AI and machine learning capabilities, such as with Siri and the new Vision Pro features. While now there is no official announcement on direct support for third-party LLMs (Large Language Models) or custom AI agent integrations, Apple has historically prioritized privacy and security, which might influence how external AI systems interact with its ecosystem. Developers could potentially integrate AI solutions via APIs, but official support for third-party LLMs would depend on Apple's future policies and updates to their software platforms, like iOS or macOS.
