Apple has announced the development of a new artificial intelligence model named ReALM (Reference Resolution As Language Modeling), which it claims surpasses the capabilities of OpenAI's GPT-4 in understanding and handling context. This includes the ability to parse contextual data more efficiently, which could significantly enhance interactions with Siri and other Apple services by understanding entities currently displayed on a user's screen. Apple's AI researchers have developed ReALM as an on-device model, emphasizing its smaller size (3B) and faster performance compared to GPT-4. The company suggests that ReALM could lead to major updates for iOS and macOS at WWDC 2024, potentially revolutionizing conversational AI by employing large language models (LLMs) for superior reference resolution across multiple entities. This breakthrough has been highlighted as a significant advancement in AI, with Apple suggesting that ReALM could be made available to developers in future iOS 18 updates.
