Google is merging ChromeOS and Android into Project Aluminium, and the timeline is more nuanced than headlines suggest. Both the "2026" and "2028" dates are accurate, each describing a different rollout phase. Here is what the platform shift means for your current device and what specifications to prioritize on your next Chromebook purchase.
Project Aluminium is Google's effort to replace the engineering foundations of ChromeOS with Android, producing a single Android-based desktop operating system. Google adopted the "-ium" metal naming pattern it established with Chromium, using the British spelling to place the "Al" prefix front and center as a reference to Android's role as the platform's base. A Google job listing for a "Senior Product Manager, Android, Laptop and Tablets" made the codename public, explicitly stating that the role involves "working on a new Aluminium, Android-based, operating system."
This is not a ChromeOS software update wearing a new label. The architecture shifts from ChromeOS's browser-first, Linux-based foundation to a full Android runtime capable of running the same apps that power Android phones and tablets. Gemini sits at the center of the new platform, not as a side-panel shortcut but as foundational infrastructure for intelligent multitasking, natural language task execution, and on-device AI processing through neural processing units.
The hardware ambition is equally significant. The same job listing confirmed three device tiers for the new platform: AL Entry, AL Mass Premium, and AL Premium, sitting alongside the existing Chromebook and Chromebook Plus tiers and covering laptops, detachables, tablets, and mini-PC-style desktop units. Development builds are running on Intel 12th Gen Alder Lake and MediaTek Kompanio 520 chipsets, establishing the hardware generation floor. Google is explicitly targeting premium hardware, not just the budget segment where ChromeOS historically succeeded.
The timing is not arbitrary. Apple's MacBook Neo, which runs a full version of macOS identical to the software on MacBook Pro M5 machines, directly challenges the affordable-premium laptop segment that Google has long struggled to crack. When a consumer can buy an entry-level MacBook and receive the same operating system as a top-tier professional machine, the pressure on Google to offer a comparable unified-OS story becomes acute. The AI laptop renaissance compounds that pressure: generative AI tools demand the keyboard, screen real estate, and multitasking capacity that laptops provide, making the form factor more relevant than it has been in years.
What we cannot yet confirm from official documentation is the final marketing name: bug reports have surfaced "ChromeOS Classic" and "non-Aluminium ChromeOS" in engineering logs, but Google has not committed to a consumer brand for the new platform.
Sameer Samat said 2026 at Qualcomm's Snapdragon Summit. Google's own antitrust lawyers described late 2026 as the "fastest path" to commercial testers, with a full release in 2028.
These two statements describe different phases of the same rollout, not competing predictions about a single launch date. Reading both against their context resolves what initially looks like a contradiction.
The legal documents, first covered by The Verge and reported by Android Authority, emerged from the Google Search antitrust remedy phase. They describe a rollout in two distinct phases: Aluminium OS available to "commercial trusted testers" in late 2026, followed by a full release targeting enterprise and education customers in 2028. Samat, speaking as Google's President of Android Ecosystem at Qualcomm's Snapdragon Summit and again at MWC 2026, confirmed the platform is targeting "later this year," telling Android Authority directly: "Yes, I'm super excited about later this year."
"2026" refers to the first public release: a launch announcement with new hardware reaching partners, developers, and early adopters. "2028" refers to the broad commercial deployment that enterprise IT departments and school districts require before they can standardize on a new platform. These are sequential stages of the same rollout, not contradictory forecasts.
We should also note that those court filings were produced in adversarial legal proceedings, where Google's lawyers had strong incentives to describe the Aluminium OS transition as slow and technically complex. In that context, the 2028 date for enterprise and education deployment is more plausibly a conservative floor than a fixed commitment.
Google I/O 2026, confirmed for May 19-20 at Shoreline Amphitheatre in Mountain View, is the most anticipated venue for a formal Project Aluminium announcement. Google's typical fall hardware window would then put consumer devices in market by September or October 2026. The platform's development is further along than the legal documents imply: the Chromium project's code repository shows active builds labeled "ALOS," with identifiable development devices including codenames like "Sapphire" (MediaTek Kompanio Ultra), "Ruby" (Intel Panther Lake), and "Moonstone" (an Acer reference device).
The working model, consistent across the available evidence, is announcement in May, hardware in fall 2026, and broader enterprise and education deployment rolling through 2027 and 2028.
The straightforward reading of "Google is replacing ChromeOS with Android" misses a more deliberate strategic move. Samat was explicit on this point at MWC 2026: "Chrome OS has done really well. Its management capability is second to none. Development for Chrome OS will absolutely continue as is." That is not the language of a platform being deprecated.
ChromeOS's strength has always been institutional rather than consumer. Education accounts for 60.1% of all Chromebook sales, and 93% of US school districts plan Chromebook purchases annually. The platform's security model, centralized device management tools, and browser-first architecture make it straightforward for IT administrators to deploy at scale across thousands of devices. Those capabilities are not easily replicated by Android, which has a more complex permission model and was built for personal devices rather than managed fleets.
Android Authority, citing The Verge's reporting on Google's antitrust court documents, confirmed Google's plan to "phase out ChromeOS" in 2034, a date tied directly to the 10-year automatic software update commitment for hardware currently being sold. A Chromebook purchased today receives ChromeOS support through at least 2036. The 2034 phase-out is a long-range sunset tied to existing contractual obligations, not an imminent discontinuation.
Meanwhile, ChromeOS 144, which began rolling out on January 27, 2026, marked the first native arrival of Gemini in Chrome for Chromebook Plus devices, enabling real-time page-level summarization and context-aware Q&A directly in the browser sidebar. ChromeOS 146, rolling out this week as a security and stability update, fits a pattern of measured feature delivery while engineering resources focus on the larger platform transition.
Our read of Samat's comments at MWC 2026 is that Google is building two parallel laptop approaches: ChromeOS for managed, browser-first deployment, and Aluminium OS for the consumer and premium segment where Apple's tight ecosystem has been winning. Rather than one platform replacing another, Google is building what Apple built with MacBook Air and MacBook Pro: differentiated products at different tiers, running a shared OS foundation, serving different primary buyers. The difference is that Google's two tracks serve genuinely different computing philosophies rather than just different price points.
John Maletis, Google's VP of ChromeOS, addressed this directly during a Chrome Unboxed AMA in January 2026. His answer was candid: "not all devices will be able to just because there are technical specifications." Google is "working on an ability" to migrate qualifying newer Chromebooks, but migration to a new OS on live hardware is a significant technical undertaking, and older devices are not candidates.
Google has not published official minimum specifications for Aluminium OS, and what we know about hardware requirements comes from testing observations rather than any confirmed technical threshold. The development test hardware, Intel 12th Gen Alder Lake processors and MediaTek Kompanio 520 chipsets, establishes a rough generation floor. Chromebook Plus certification, which launched in late 2023 and requires Intel 12th Gen or equivalent, 8GB of RAM, and 128GB of storage, looks retrospectively like a preview of what Aluminium OS will need.
Any Chromebook meeting Chromebook Plus certification from 2023 or newer is the strongest candidate for Aluminium OS compatibility. These devices already meet the processor generation and memory thresholds that active development hardware uses. Devices with MediaTek Kompanio 520 or newer, AMD Ryzen 5000-series processors or newer, and at least 8GB of RAM fall into the same probable eligibility range. An opt-in upgrade path is the likely model for these devices, not an automatic migration.
Budget Chromebooks with Intel Celeron or Pentium processors from before 2022, or any device with 4GB of RAM, are almost certainly outside Aluminium OS's reach. These devices' processors lack the neural processing unit capabilities that Aluminium OS's AI-first architecture depends on, and 4GB of RAM is insufficient for the memory demands of on-device AI inference alongside standard multitasking. These devices will continue receiving ChromeOS Classic updates under the 10-year automatic update commitment, with security support through their Auto Update Expiration date.
Education accounts for 60.1% of all Chromebook sales. The minimum hardware requirements emerging for Aluminium OS, Intel 12th Gen or newer processors and 8GB or more of RAM, exclude precisely the kinds of budget devices that dominate classrooms.
The Chromebook fleet most exposed to this compatibility cliff is the one that made ChromeOS a success. The $200-to-$300 Celeron machines that populated K-12 classrooms over the past decade were built to run a browser efficiently, not to power an AI-native desktop OS. School districts that standardized on these devices will run ChromeOS Classic through their support windows and face a genuine hardware refresh decision when those windows close, not an upgrade path to Aluminium OS.
Google's Android 17 development confirms that the ecosystem infrastructure for Aluminium OS is being built now, ahead of any hardware launch.
Android Authority's interview with Sameer Samat at MWC 2026 confirms cross-device continuity as a primary Aluminium OS value proposition. Samat described phone-to-laptop interoperability as a major focus: "A lot of Android users are excited about the ability to have their phone and their laptop interoperate and work better together." The infrastructure for that capability is not being planned alongside Aluminium OS hardware. It is shipping now.
Android 17 Beta 2's Handoff API specifies exactly how the system will synchronize application state between nearby devices via CompanionDeviceManager, and it already works on phones and tablets today. The Android Developers Blog documents the feature: when an app opts in, the system "synchronizes state via CompanionDeviceManager and displays a handoff suggestion in the launcher of the user's nearby devices." The official Android 17 developer documentation specifies that the API "allows the user to start an app activity on one Android device and transition it to another Android device," with developers implementing it at the per-activity level through the setHandoffEnabled() method.
This suggests that by the time Aluminium OS launches on laptops, the phone-to-laptop continuity infrastructure will already be mature across the Android ecosystem. Phones and tablets will know how to pass application state to a nearby Aluminium OS device before a single Aluminium OS laptop reaches a consumer. When the receiving device does not have the native app installed, a web-based URL fallback preserves continuity regardless. The ChromeOS and Android merger is advancing at the operating system layer, with the foundation being laid in software before hardware arrives.
Apple built its Handoff equivalent years before offering Macs at budget price points. Google is building its cross-device infrastructure into Android 17 before Aluminium OS hardware ships. The sequence is deliberate.
ChromeOS 146, which began rolling out on March 25-26, 2026, is a security and stability release with no major user-facing features. This has been the pattern for several ChromeOS cycles, reflecting where Google's engineering attention is concentrated. The meaningful question for anyone with a Chromebook is not what ChromeOS 146 offers but where their device sits in the compatibility picture.
The recommended future-proofing specs, 8GB or more of RAM, 128GB or more of storage, and an Intel 12th Gen or newer processor or AMD Ryzen 5000 series equivalent, come from compatibility analysis rather than official Google documentation. That distinction matters: Google may set different final thresholds, and the picture will become clearer at Google I/O 2026 in May.
Prioritize Chromebook Plus-certified devices. The specifications that define Chromebook Plus certification align closely with the hardware generation floor appearing in Aluminium OS development builds. A device purchased now in the Chromebook Plus tier gives the strongest probability of qualifying for an Aluminium OS upgrade path when it becomes available, while also carrying a ChromeOS support commitment through at least 2036. The premium Chromebook Plus tier, which ranges from $349 to $699, represents the realistic hardware floor for Aluminium OS readiness, not the budget tier below it.
If you are comparing platforms before committing to the Google ecosystem, understanding what each OS permanently gives up to deliver its headline strength can help you make a decision based on real trade-offs rather than feature lists. That context matters especially now, with ChromeOS and Aluminium OS coexisting for the next several years across different buyer profiles.
If budget is the primary constraint and a $200-to-$300 device is the target, that purchase makes sense for users whose needs are browser-first and education-focused. Those users are the intended long-term audience for ChromeOS Classic, which will continue receiving updates on its existing schedule. The trade-off is clear: budget hardware is a ChromeOS device permanently, not a stepping stone to Aluminium OS.
Devices purchased from 2022 onward with 8GB of RAM and Intel 12th Gen or equivalent processors are plausible Aluminium OS candidates. Google is "working on an ability" to migrate qualifying hardware, per Maletis's January 2026 confirmation. The clearest signal of eligibility will arrive at Google I/O in May. There is no action required now beyond tracking the announcement.
Devices on 4GB of RAM or Celeron/Pentium processors from before 2022 will not receive Aluminium OS. ChromeOS Classic continues through the device's Auto Update Expiration date, providing security updates on schedule. The practical question is whether that support window aligns with the natural hardware replacement cycle. A device with two or more years of support remaining represents meaningful remaining value on ChromeOS Classic, even without a path to Aluminium OS.
The platform transition is real, the timeline is more defined than the debate suggests, and the device decision framework is straightforward. Chromebook Plus specs purchased today put a device in the strongest position for whatever Google announces at I/O in May. Everything below that tier is a commitment to ChromeOS Classic for its remaining support life, which for recently purchased devices remains substantial.
Google I/O 2026 takes place May 19-20, 2026, at Shoreline Amphitheatre in Mountain View, California. It is expected to serve as the first venue for a formal Project Aluminium announcement. Hardware is anticipated in fall 2026.
