Apple Intelligence Explained: Why Older iPhones Don’t Get It

And Why your iPhone 15 and iPhone 14 (or older) just isn’t powerful enough

Apple is redefining AI on iPhone, but only if you own the right one. Here’s why most iPhones are missing out on Apple Intelligence.

The Big Question: Why Doesn’t Your iPhone Support Apple Intelligence?

Apple Intelligence is a deeply integrated, privacy-focused generative AI system, alongside iOS 18, macOS Sequoia, and iPadOS 18. But only the iPhone 15 Pro, 15 Pro Max, and iPhone 16 series support the full experience. If you’re using a standard iPhone 15 or anything older, the new AI features are missing.

So, is Apple holding back AI features to push you into an upgrade? Let’s unpack the real story.

Apple Intelligence Needs Serious Hardware Power

According to Apple, the reason for this limitation is simple: older iPhones aren’t powerful enough.

• Only iPhones with A17 Pro (15 Pro/Max) and A18/A18 Pro chips (16 series) include a 16-core Neural Engine capable of up to 35 trillion operations per second (TOPS). This kind of horsepower required to run large AI models on-device.
• These iPhones also pack 8 GB of RAM, which is essential for handling the memory-intensive workloads AI features demand. Older iPhones typically come with 6 GB RAM or less.

Apple Intelligence uses a 3-billion-parameter large language model (LLM) to power things like natural language understanding, text generation, and Genmoji, all of which require plenty of computing headroom.

Slower iPhones = Bad AI Experience

Apple’s Senior VP of Machine Learning and AI Strategy, John Giannandrea, put it bluntly at WWDC 2024: older devices could technically run Apple Intelligence, but the experience would be “so slow, it would not be useful.”

In other words, it wouldn’t just be a “lite” version, it would be frustratingly laggy, unreliable, and a bad look for Apple.

Privacy First: On-Device Processing or Nothing

Unlike cloud-based models from Google or OpenAI, Apple Intelligence prioritizes on-device processing. That means your prompts, photos, and data stay on your iPhone unless absolutely necessary.

• Apple Intelligence taps into the cloud only when your device can’t handle a task, and even then, it routes through a privacy-first infrastructure called Private Cloud Compute, which doesn’t store or retain your data.

But that privacy-centric model demands powerful, local hardware. And again, older iPhones just don’t make the cut.

These Are the Only iPhones That Support Apple Intelligence

As of iOS 18 and moving into iOS 26, the following devices support Apple Intelligence:

• iPhone 15 Pro
• iPhone 15 Pro Max
• iPhone 16 Series
• Upcoming iPhone 17 Series

On the iPad and Mac side, any device with an M1 chip or later is supported, including the iPad Pro M1+, iPad Air M1+, and all M-series Macs.

If your iPhone has an A16 chip or older, it’s out.

What Can Apple Intelligence Actually Do?

Here’s what you’re missing out on without Apple Intelligence:

• Genmoji: Create emojis from your text descriptions
• Writing Tools: Rewrite, proofread, and summarize text in Mail, Notes, and Safari
• AI Summaries: TL;DR for emails, web pages, and long documents
• Image Playground: Instantly generate images in 3 styles: animation, illustration, sketch
• Smart Siri: A dramatically more capable Siri that understands context and multitasks
• On-Call Live Translations
• AI-Powered Reminders & Calendar Suggestions

And the list is growing with iOS 26, as Apple Intelligence continues evolving.

Is Apple Just Forcing You to Upgrade?

It’s a fair question. On the surface, limiting AI to only the newest (and most expensive) iPhones looks like a sales tactic. But Apple’s position is that this decision is driven by performance, not profits.

Again, Apple’s top AI executive insists that if the tech worked acceptably on older devices, they’d have included them.

Also, Apple didn’t even bring Apple Intelligence to all M1 Macs or iPads right away, another sign this isn’t just about upselling.

Will Older iPhones Get Some AI in the Future?

Possibly.

• Apple could roll out cloud-based or lighter AI features later down the road.
• But full Apple Intelligence is likely to stay exclusive to Pro-tier devices and future models with at least A17 Pro or better chips.

Until then, most users won’t see Genmoji or Siri’s big brain upgrade unless they own the right iPhone.

TL;DR – Why You Need a New iPhone for Apple Intelligence

Final Thoughts

Apple isn’t locking you out of AI for fun, it’s setting a technical and privacy bar that older iPhones just can’t reach. If you’re on an iPhone 14 or earlier, you’ll still get iOS updates and some smart features, but the full Apple Intelligence experience remains out of reach, for now.

It’s a bold bet on performance, privacy, and the future of mobile AI. And it’s just getting started.
