Software researcher pdfu posted a video to X on September 23 showing what Siri AI reportedly looks like and sounds like on HomePod. Apple has not publicly confirmed any of it, and the feature does not currently activate on existing HomePod models. For broader context on Apple’s hardware strategy, see coverage of AI chips and Apple’s next-generation silicon roadmap.
HomePod Software 27, also called audioOS 27, reportedly contains code tied to “Linwood,” the internal system behind Apple’s redesigned Siri AI experience. That finding comes from pdfu’s discovery, not from Apple.
What the Leak Actually Shows
A new look, new sounds, and a familiar color palette, all hidden inside software your HomePod already downloaded.
According to pdfu’s post on X, the code includes a redesigned Siri interface with new visual status lights and updated audio feedback. The color palette reportedly emphasizes white, blue, and orange, matching the Siri AI presentation Apple uses across iPhone, iPad, and Mac.
That visual consistency may suggest Apple is working toward a unified Siri identity across its device lineup, HomePod included. It is an inference from the leak, not a confirmed design strategy.
The video pdfu shared includes sound, which 9to5Mac noted points to Apple reworking not just the visual indicator but also the audio cues Siri uses during interactions. MacRumors reported on the same findings, and every detail originates from the leak. Apple has not publicly confirmed these details in the cited materials.
Why Your Current HomePod Can’t Use It
The code is sitting there. The feature is not switching on. That gap is the whole story.
HomePod Software 27 reportedly contains Siri AI-related code, yet the feature remains inactive on current HomePod hardware. Tom’s Guide noted that existing HomePods “still do not activate Siri AI despite the relevant software being available.”
Observers have drawn a reasonable inference from that gap. Apple may be reserving Siri AI for new HomePod hardware not yet announced, possibly because the feature demands more processing capacity than current models carry. That is speculation, not a confirmed hardware requirement, and pdfu described a new hardware requirement as a possibility, not a certainty.
Apple’s official Siri AI announcement named iPhone, iPad, Mac, Apple Watch, and Vision Pro as supported devices. HomePod did not appear on that list, making the leak the principal public evidence that the feature is heading to Apple’s smart speaker at all.
If new hardware turns out to be required, this becomes an upgrade decision rather than a free software update. That distinction matters to HomePod owners who expected their device to stay current through software alone.
Apple has not publicly announced pricing, a product name, a release date, or compatibility details for any Siri AI-capable HomePod. The honest read on pdfu’s discovery is that the leak indicates Apple may be preparing Siri AI for HomePod, and that preparation is far enough along to leave traces in released software. That is meaningful evidence of development. It is not a launch announcement, a compatibility guarantee, or a reason to clear space on your kitchen counter just yet.
