A leaked internal Apple iOS 26 build has been making the rounds for weeks, and it’s turning into one of the most revealing early looks at Apple’s upcoming product roadmap in years. The build reportedly surfaced after a prototype Apple device running an early developer version of iOS 26 (said to have been labeled iOS 19 internally) ended up being sold. Once the buyer got access, they discovered references to unannounced hardware scattered throughout the software.
After that, an anonymous source shared the details more widely, and the steady stream of leaks began. Now a well-known Chinese tipster, “Kang” on Weibo, has pulled the key information together into a single summary—essentially a cheat sheet of device codenames and model identifiers that point to Apple products expected across the next several release cycles. Below is a rewritten, reader-friendly breakdown of what the leaked iOS 26 build appears to reveal.
Apple Silicon: new A-series, M-series, and more chips on the way
One of the biggest takeaways is how many next-generation chips are referenced. Internal model numbers and codenames suggest Apple is actively developing future iPhone, Mac, Watch, and connectivity silicon—some of which could define hardware releases for years.
A20 chip (model T8160) shows up under the codename Banda
A20 Pro is listed as Borneo
S11 chip appears as model T8320
S12 chip is also tied to model T8320, with the codename Nevis
M6 chip is identified as model T8152, codename Komodo
M7 chip appears as model T8162, codename Delos
For higher-end Macs, the leak references a full spread of M5 family chips:
M5 Pro (model T6050), codename Sotra S
M5 Max (model T6051), codename Sotra C
M5 Ultra (model T6052), codename Sotra D
There’s also an uncertain entry: an R2 chip (model T6502), codename Corfu, though the leak suggests this one may not be fully confirmed. And for short-range device tracking and location features, a U3 Ultra Wideband chip is listed as model T2034—an especially interesting detail given the growing focus on tracking, proximity experiences, and smart home integration.
Home and smart devices: AirTag 2, HomePod mini 2, and even a tabletop robot
The leaked build doesn’t just point to phones and computers. It also hints that Apple’s smart home push is expanding beyond existing Apple TV and HomePod categories. Alongside prior chatter about a dedicated home hub product sometimes called “HomePad,” the internal iOS 26 references suggest multiple hub variations and additional accessories.
AirTag 2 is referenced as model B589
A second-generation Studio Display appears as J427 and J527
A new Apple TV is listed as J355
Two home hub variants are mentioned:
Home hub variant 1 with a base (model J490)
Home hub variant 2 that’s mounted (model J491)
There’s also an “unknown home accessory” labeled J229. The possibilities floated include a standalone base that could pair with the mounted hub, or a completely separate device such as a home camera.
Most surprising is a “tabletop robot” referenced as model J595—an eye-catching clue that Apple could be experimenting with a more interactive home device category. Rounding out the list, HomePod mini 2 appears as model B525, hinting at a long-awaited refresh.
Wearables and headset plans: Vision Air, Vision Pro updates, and smart glasses development
Apple’s wearable roadmap in the leak paints a picture of multiple parallel experiments: lighter mixed-reality hardware, iterations on Vision Pro, and smart-glasses-style devices.
Vision Air headset is listed as model N100, described as a lighter, cheaper take on the Vision concept
An AR glasses prototype appears as N421, described as likely scrapped
Mac-connected AR glasses are shown as N107, also described as scrapped
A cheaper Vision Pro appears as N109, described as a second-generation Vision Pro distinct from Vision Air
The leak also points to “AI smart glasses,” originally model N50, though Apple reportedly now refers to them as N401. The positioning suggests a consumer-friendly smart glasses product designed to compete with popular camera-and-AI-enabled eyewear.
On the Apple Watch front, two major future models are listed:
Apple Watch Series 12: N237 and N238 (Wi‑Fi and Cellular)
Apple Watch Ultra 4: N240
Mac roadmap: an A18 Pro MacBook and multiple M5/M6 Mac lines
Mac fans may find this section especially intriguing. The leak suggests Apple is not only continuing its M-series cadence, but is also exploring a lower-cost MacBook that uses an iPhone-class chip.
A low-cost MacBook with A18 Pro is listed as J700
For the next MacBook Pro line, multiple entries suggest both 14-inch and 16-inch variants with M5 Pro and M5 Max configurations:
M5 Pro/Max MacBook Pro: J714c, J714s, J716c, J716s
MacBook Air updates also appear:
M5 MacBook Air: J813 (13-inch) and J815 (15-inch)
Desktop Macs are included too:
M5 Mac Studio: J775c and J775d (M5 Max and M5 Ultra variants)
M5 Mac mini: J873g and J873s (M5 and M5 Pro variants)
And the leak goes further into the future with M6-era MacBook Pro listings:
M6 14-inch MacBook Pro: J804
M6 Pro/Max MacBook Pro: K114c, K114s, K116c, K116s (14-inch and 16-inch with M6 Pro and M6 Max)
iPads: iPad 12, iPad mini 8, and multiple iPad Air paths
The iPad lineup referenced in the leak spans entry-level to pro-adjacent configurations, with multiple generations hinted.
iPad 12: J581 (Wi‑Fi) and J582 (Cellular)
M4 iPad Air appears with multiple models covering 11-inch and 13-inch sizes, Wi‑Fi and Cellular:
J707, J708, J737, J738
iPad mini 8 is listed with an A20 Pro chip:
J510 and J511
There’s also mention of iPad Air 8 using an M4 chip and potentially a C1 or C1X modem, referenced as:
J7x7 and J7x8
iPhones: iPhone 17e, iPhone 18 Pro lineup, and a foldable iPhone
Finally, the leaked iOS 26 build references several iPhone identifiers that point beyond the next immediate launch.
iPhone 17e: V159
iPhone Air 2: V62 (with a note that the software predates a decision to delay the launch)
iPhone 18 Pro: V63
iPhone 18 Pro Max: V64
Foldable iPhone: V68
That last one—the foldable iPhone entry—is likely to generate the most attention, as it suggests Apple’s foldable plans may be far enough along to be showing up in internal software builds.
Big picture: why this leak matters
What makes this iOS 26 leak especially compelling is its breadth. Instead of focusing on one product, it hints at Apple’s direction across silicon, smart home devices, wearables, Macs, iPads, and iPhones—complete with internal model numbers and codenames that typically stay hidden until much closer to launch. Of course, plans can change, prototypes can be canceled, and internal identifiers don’t always guarantee a product will ship. But as a snapshot of what Apple has in development, this internal build may be one of the clearest early maps of what’s coming next.
