For a while now, Apple has been teasing a future where Siri finally feels less like a voice-controlled shortcut button and more like a genuinely helpful assistant. The kind that understands what you mean, remembers what matters (in a privacy-friendly way), and can actually do things across your apps without you having to babysit every step.

But according to a new report, Apple's "next Siri" is currently struggling in internal testing, and that could push some of the most exciting upgrades further down the road than Apple originally hoped.

What Apple Was Aiming For, And What Might Change

Bloomberg's Mark Gurman reports that Apple had been targeting an upgraded Siri rollout around iOS 26.4, which was reportedly lined up for early 2026. Now, due to issues uncovered in test builds, Apple is said to be considering spreading features across later updates such as iOS 26.5 (around May 2026), and potentially pushing some bigger pieces even further out into iOS 27 (around September 2026). Apple reportedly declined to comment on the report.

If this sounds familiar, it's because this Siri overhaul has already had a long runway. Apple showed the vision publicly back in 2024, with expectations that the "smarter Siri" era would land sooner than it's now shaping up to.

The Siri Apple Promised: Personal Context, On-Screen Awareness, Real App Control

When Apple introduced its Apple Intelligence direction, the Siri story wasn't just "talk to your phone better." It was "Siri will understand your world."

Apple positioned Siri upgrades around ideas like:

The demo-friendly examples are easy to imagine: "Find that podcast my friend sent me weeks ago and play it," or "Use the info on my screen and add it to a contact," without the usual Siri back-and-forth.

What's Going Wrong In Testing, According To The Report

The core issue, as reported, is reliability. And with assistants, reliability is everything. A feature can be amazing on paper, but if it works seven times out of ten, people stop trusting it fast.

Bloomberg's sources say internal builds are showing problems like:

That kind of stuff sounds small until you picture it in real life: you're walking, driving, cooking, or juggling ten things, and your assistant decides this is the perfect moment to freeze, mishear you, or interrupt you.

The Features Most At Risk Of Sliding

From the reporting, two "big ticket" capabilities seem especially vulnerable to delays.

Deeper personal-data intelligence

This is the stuff that makes Siri feel truly personal: searching across messages, files, and other personal content to answer real-life questions. The report suggests Apple may ship this in a limited or preview-style form first, which often means "it's not fully ready, but we want people to start trying it."

Advanced app actions (App Intents)

These are the "do a whole workflow for me" commands. Think: "Find that photo, edit it this way, and send it to this person." Reports say early support exists in iOS 26.5 builds, but it isn't consistently reliable yet.

The Awkward Part: Siri Falling Back To ChatGPT When It Shouldn't

One of the more interesting details in the reporting is that Siri has apparently been defaulting to its ChatGPT integration at times when Apple's own system is expected to handle the request.

That's not necessarily a "bad" outcome for the user in the moment (because the answer might still be good), but strategically it's a problem: Apple wants Siri to feel like it has its own brain, not like it's constantly outsourcing.

New Siri, New Engine: What "Linwood" Is Supposed To Be

Under the hood, the report describes a newer Siri architecture (said to be codenamed Linwood) that's built around Apple's large language model efforts, often referred to as Apple Foundation Models.

Apple has publicly talked about its Foundation Models framework and Apple Intelligence direction, and the reporting suggests Siri's rebuild is meant to sit on top of that foundation.

Extra Rumored Add-Ons: AI Web Search And Image Generation

Bloomberg also reports that internal builds include signs of additional AI features, like:

The important detail, though, is that testers reportedly describe these as inconsistent right now. Which fits the broader theme: Apple may be building a lot, but the "ship it" moment depends on whether it behaves predictably at scale.

Looking Past iOS 26: The Bigger Siri Shift Reportedly Planned For iOS 27

Even while Apple wrestles with the near-term Siri upgrade, Bloomberg has also reported on a more dramatic next step: a chatbot-style Siri experience for iOS 27, iPadOS 27, and macOS 27, associated with the codename "Campos."

This is the direction most users already expect in 2026: something more conversational, more context-aware, and more like modern generative AI assistants—while still staying within Apple's privacy-first boundaries.

Why This Delay Matters (And Why Apple Might Accept It)

If the reports are accurate, Apple is choosing the slow path for a reason: assistants become part of daily habit. If Siri gets a reputation for being flaky, it's hard to win people back—even if the next update is better.

So while it's frustrating to see big promised features slip again, the more important question is whether Apple can deliver them in a way that feels solid, fast, and trustworthy. Because for Siri, "almost works" is the same as "doesn't work" in real life.
