Apple CEO Tim Cook officially confirmed during the company’s Q4 2025 earnings call that a "reimagined" and "more personalized" Siri is scheduled for release in the first half of 2026. This timeline aligns with the expected rollout of iOS 26.4, marking the most significant architectural shift for the assistant since its inception. According to official corporate transcripts, this update focuses on "deep reasoning" and "personal context," moving Siri from a command-based tool to an agentic intelligence system.

To support these advanced capabilities, Apple’s latest SEC Form 10-K filing details a massive expansion of "Private Cloud Compute" (PCC). This verified infrastructure allows Apple to utilize high-parameter, third-party large language models (LLMs) on secure, end-to-end encrypted servers. By routing complex requests to PCC, Apple can provide the reasoning power of a trillion-parameter model while legally and technically ensuring that user data remains inaccessible to both Apple and its foundational model partners.

On the hardware front, official Apple Developer documentation for the "Apple Intelligence SDK" confirms a strict technical "floor" for these new features. The documentation specifies that "Advanced Semantic Indexing" and "Multi-Step App Intents"—the core technologies behind the new Siri—require a minimum of 8GB of Unified Memory. This officially verifies that the iPhone 15 Pro, which was the first Pro model to feature 8GB of RAM and the A17 Pro chip, is the baseline device required for the 2026 update.

This shift is mirrored in recent financial disclosures from Alphabet (Google), which reported record-breaking capital expenditures exceeding $90 billion for AI infrastructure in 2025. In their January 2026 investor updates, Google leadership confirmed the company has established long-term "foundational logic" licensing agreements with global hardware partners. These combined corporate filings confirm that Apple is leveraging external model expertise to power Siri's logic, while maintaining total control over the user experience and data privacy through its own silicon and cloud architecture.
