New Apple Siri iOS 26.4 Compared With ChatGPT 2026
One year ago, Apple said Siri would get better. Now, ChatGPT has made that happen. What does that mean when you actually use them? A look at how they perform today - just what works, what doesn’t. Real differences show up fast.
Inside Siri and iOS 26.4
Surprise waited for Apple followers when iOS 26.4 arrived without change. Months earlier, whispers from Mark Gurman at Bloomberg hinted this version would carry a smarter Siri built on large language models. That kind of shift had been stuck in delay after delay. Late March often brings x.4 versions, so eyes turned that direction in 2026. Hopes rose quietly, then faded just as fast once the files landed.
Then reality hit.
By early 2026, Gurman noted Siri’s upgraded tools would miss the iOS 26.4 release due to lingering precision problems. Performance fell short of expectations. Yet Apple chose transparency instead of silence. It told CNBC the updated version remains set for a 2026 debut - just not tied to that particular update cycle.

What the new Siri was meant to do
For a fair look at this matchup, consider Apple’s roadmap - things still on the drawing board count too.
Later than expected, Apple's enhanced Siri finally showed up during WWDC 2024. Instead of launching with iOS 18 in 2025, its debut got pushed - once, then again. The spotlight fell on three traits: knowing what’s on screen, using personal details, doing tasks across apps.
This time around, Siri feels different because of how it’s built underneath. Instead of following fixed rules, Apple has rebuilt the assistant using a system similar to what drives ChatGPT. The core shift? A move toward patterns learned from vast amounts of text. That changes how it understands questions. Behind the scenes, it now relies on predictions rather than scripts. What you get is a more fluid way of responding.
Later that week, Apple teamed up with Google to reveal a long-term partnership. This deal, announced January 12, 2026, centers on future versions of Apple’s core AI systems. Instead of building everything alone, Apple will now use Google’s Gemini models and cloud tools. Siri’s brain will evolve using those components. Despite relying on Google’s infrastructure, Apple insists its strict privacy rules won’t change. Performance gains are expected without compromising user data handling. Details surfaced via reporting from 9to5Mac
A fresh version of Siri - known behind the scenes as "Campo" - is showing up as its own chat-focused app. This move places it right alongside tools like ChatGPT and Google Gemini. Strange, really, coming from a firm that long claimed Siri wasn’t a chatbot but something else entirely: an assistant. Years of pushing that line make this change stand out sharply.
ChatGPT in April 2026 Current Status
Even as Apple struggles with setbacks, OpenAI pushes ahead, rolling out new features without pause.
By April 2026, ChatGPT operates using GPT-5.4 Thinking as its main brain. Back on March 11th that year, older GPT-5.1 versions vanished completely. In their place stepped three new models - GPT-5.3 Instant, GPT-5.4 Thinking, and GPT-5.4 Pro - each shaped for distinct tasks. A single thread of thought can now stretch across a full million tokens. That allows it to follow massive files or chat trails without slipping off course. Details are pulled straight from OpenAI's official notes
ChatGPT Features Available Now
ChatGPT pulls together facts from various places, building thorough summaries on complex topics. This ability stands out most for professionals, say several separate evaluations.
Stashed files live on, ready whenever you need them again. This shifts ChatGPT from fleeting talk to a place that remembers. Instead of starting fresh each time, your stuff stays put. Open up old docs like flipping through a drawer you left half-open yesterday. Each visit picks up where the last one ended. Not magic - just memory built in. The screen becomes more workshop than chatbox.
ChatGPT grabs live info straight from the web, citing sources as it goes. Instead of just listing links, it pulls together up-to-date details on its own. When checking products, breaking news, or step-by-step help, it lines up facts like a quick reader scanning pages in real time. While regular search waits for clicks, this moves ahead without pausing. Each answer ties back to what's online right now, not yesterday.
Back in March 2026, something new showed up - students now tweak math and science equations live. More than seventy subjects are ready to go, each one built for hands-on exploring instead of just watching.
Inside your car, something odd just showed up. Right within Apple CarPlay, ChatGPT now speaks back when you talk - no touching needed. This shift came quietly through iOS 26.4, slipping in while everyone waited for a smarter Siri. Conversations pick up where they left off, even mid-drive. A feature meant to upgrade one helper ended up inviting another. Not from Apple. From OpenAI instead. Found hiding in release notes posted by Releasebot
Fine. ChatGPT arrived for iOS 26.4. Siri stayed away. That happened.
Siri iOS 26.4 Compared With ChatGPT
Siri feels behind at version 26.4 while ChatGPT runs ahead using GPT-5.4 in April 2026. Instead of full onscreen understanding, Apple waits - ChatGPT sees through vision mode but still stumbles. Digging into deep research? Siri skips that. ChatGPT handles it like routine. Search live online - Apple offers scraps. OpenAI serves fresh results with sources tagged. Both talk inside cars, though Apple sticks to basic prompts whereas the other flows naturally. No standalone bot lives on iPhones yet; meanwhile, one already sits ready elsewhere. Jumping between apps during tasks stays out of reach for now on Apple’s side, unlike linked experiences found elsewhere. Memory depth drags on limited ground within Siri, compared to nearly a million token span used by its rival. Privacy leans on local tools plus secure storage at Apple, versus pure cloud reliance seen elsewhere. Money talks: free if you own an Apple tool, or pay later for extras when choosing the alternative. Right now, there is no real match - and Apple sees every gap clearly. This pressure shapes what must come next.
Apple’s Real Advantages
Truth is, Apple’s not out of the game. It’s merely showing up later than expected.
Privacy stands out as Apple’s biggest strength. Wherever feasible, the updated Siri operates directly on your device. When tasks require more power, they shift to Apple’s secure cloud system built for privacy. Unlike that setup, every request to ChatGPT goes through OpenAI’s remote servers. People focused on keeping data private see this gap clearly. That distinction matters most to those watching how their information moves.
Inside Apple’s world, Siri moves through devices like air - silent, everywhere. Across phones, tablets, computers, even that coming HomePad speaker. Built right into the system, no add-ons needed. ChatGPT? It sits on top, separate, an outsider app you open when needed. Not part of the bones. One runs with the machine, the other beside it.

ChatGPT's Honest Weaknesses
Still, ChatGPT has its flaws. Here's what stands out:
February 2026 brought ads to ChatGPT, even though it began without them. Promises flew early on - claims of neutral suggestions, untouched by bias. Yet when money from advertisements shows up, staying true to such pledges grows tougher. Over months, ideals tend to bend under new pressures.
Right now, ChatGPT falters when asked about places nearby, such as the closest good eatery. While using an iPhone, Siri handles local searches better, despite its simpler design. Location smarts and ties to Apple Maps give it an edge over the newer tool.
ChatGPT might be strong, yet it needs its own app plus focused effort to start up. Siri floats around quietly instead. Say “Hey Siri,” then answers come right away. This ease of reaching it matters most when doing small things fast.
The Bottom Line
These days, come April 2026, ChatGPT runs ahead as the sharper AI helper. Not an opinion meant to stir - just how things sit. With GPT-5.4 under its hood, Deep Research on tap, a File Library within reach, live web lookups, even CarPlay tagging along, it simply covers more ground. Still.
Yet Apple still has moves left. Come September 2026, when iOS 27 arrives packed with a full-scale Siri driven by Gemini and powered by large language models, things shift. That version sees what's on screen. It knows your habits. Works across apps. Suddenly, the picture changes. Not so one-sided anymore.
Showing up late? That’s Apple’s habit. Yet when it finally arrives, the work often feels polished. Some wonder if people will sit tight till September. Others already call out to ChatGPT through CarPlay, skipping the wait entirely.
