Apple is finally ready to introduce a redesigned Siri, according to new reports pointing to an imminent debut in the iOS 26.4 beta. After years of anticipation, the upgrade aims to deliver the intelligent assistant Apple first promised during the early days of Apple Intelligence.

The new Siri is expected to appear in beta testing within weeks, with a public release likely later this spring. Industry observers say this marks one of Apple’s most significant AI milestones in recent years.

The updated Siri will rely on Apple Foundation Models version 10, a powerful internal AI system with roughly 1.2 trillion parameters. This represents a massive leap from Apple’s previous models, which contained around 150 billion parameters. As a result, Siri should respond more naturally and understand context with greater accuracy.

Although Apple reportedly signed an agreement to leverage Google’s Gemini technology to meet development timelines, users will not see any Google branding. Instead, Apple will present the system as a fully in-house innovation, hosted securely on its Private Cloud Compute infrastructure.

Smarter, More Personal Interactions

One of the most notable improvements involves deeper integration with personal data. The new Siri will better understand information stored across apps, messages, and system history. This allows it to answer more complex questions, such as recalling past interactions or relationships.

Previously teased demonstrations—like Siri remembering where a user met someone—could finally become real features. However, Apple remains cautious about how and when it highlights these capabilities.

Announcement Timing Raises Questions

Reports suggest Apple may preview the new Siri in late February, even though iOS 26.4 is not expected to launch publicly until March or April. This gap has raised concerns, as Apple has missed similar deadlines in the past.

Still, analysts believe Apple wants to rebuild confidence after prolonged delays. Therefore, the company may quietly introduce the features through developer briefings instead of a major keynote.

A Critical Moment for Siri

Ultimately, the iOS 26.4 release could redefine Siri’s role across Apple devices. If successful, the upgrade may finally position Siri as a competitive AI assistant in an increasingly crowded field.
