Fire TV Family Explained: Sticks, Cube and the Vega OS Switch

Amazon sells more streaming sticks than anyone, and its lineup has been simple for years: a cheap stick, a better stick, a box. In 2025 and 2026 that changed. Amazon started moving its new devices from Fire OS, which is built on Android, to a Linux-based system it calls Vega OS. Two sticks that look almost identical in the box can now run different software, with different app catalogs and different rules about what you can install.

This guide covers the family as of November 2026, using Amazon's published specs and the developer documentation it publishes for app makers. We haven't tested these devices for this article; where a detail is still settling, we say so.

The current lineup at a glance

There is also an HD stick for 1080p TVs, which moved to Vega OS in its newest version. Older models, such as the Fire TV Stick 4K Select from 2025 and the Android-based Fire TV Stick 4K renamed "4K Plus," still turn up at retailers. Check the operating system on the product page before you buy, because that is now the biggest difference between models.

Fire OS and Vega OS: why the software matters

Fire OS is a fork of Android. That is why a Fire TV stick could, for years, run almost any Android TV app, including ones Amazon never listed in its store. Kodi, alternative Plex clients, emulators and file managers all found their way onto Fire sticks through sideloading.

Vega OS drops Android. Apps have to be rebuilt for it, and Amazon only allows installs from its own Appstore. The major streaming services were ready at launch, so for Netflix, Prime Video, YouTube, Disney+, Max and the like the experience is close to the old one. The gaps show up in smaller apps: niche sports services, regional broadcasters, IPTV players and anything that relied on sideloading. Early owners of Vega devices also reported missing apps and software bugs, which Amazon has been patching through updates.

Amazon has said its future Fire TV streaming devices will run Vega OS. Fire OS keeps getting updates on the models that already have it, but if you depend on an app outside the mainstream, the 4K Max and the Cube are the last Fire TV devices where you can count on it running.

Fire TV Stick 4K (2026)

This is the stick most people will see on sale. It handles 4K at up to 60 frames per second with HDR10, HDR10+ and HLG, and it has Wi-Fi 6. It does not output Dolby Vision. On a TV that supports Dolby Vision, that means titles mastered in Dolby Vision play in HDR10 or HDR10+ instead. On many Samsung TVs, which never supported Dolby Vision, you lose nothing.

The new remote is simpler than older Fire remotes. Early reports say it drops the rewind and fast-forward buttons and has no backlight, which matters if you watch in the dark. The stick draws power over USB-C and, in some regions, ships without a wall adapter, relying on the TV's USB port. If your TV's port is weak, the stick may reboot or run slowly; a separate 5V adapter fixes that.

It suits a buyer who uses the big apps, wants HDR10+ at a low price and doesn't care about installing anything else.

Fire TV Stick 4K Max

The 4K Max, released in 2023, is Amazon's best stick and still runs Fire OS. It supports every major HDR format, including Dolby Vision and HDR10+, plus Dolby Atmos audio. Wi-Fi 6E gives it access to the 6 GHz band, but only if your router supports it; on an older router it behaves like a Wi-Fi 6 device. It has 16 GB of storage, twice what most sticks have, which helps if you install many apps.

The Max also has Amazon's Ambient Experience, which turns the idle TV into a photo frame or widget display. Amazon puts it on sale often, and at sale prices it is the default Fire TV recommendation for most people with a Dolby Vision TV.

Fire TV Cube

The third-generation Cube from 2022 is a small box rather than a stick. It has an octa-core processor, far-field microphones for hands-free Alexa, a built-in Ethernet port, and an HDMI input. That input lets you route a cable or satellite box through the Cube and control it by voice. Picture formats match the 4K Max.

The Cube is the right choice for three kinds of buyers: people who want to talk to the TV without picking up a remote, people with a cable box they want to fold into the Fire TV interface, and people whose Wi-Fi near the TV is poor enough that a wired connection matters. Everyone else gets the same picture from the cheaper 4K Max.

Alexa, ads and privacy

Every Fire TV device ships with Alexa in the remote. Amazon has been rolling out Alexa+, its newer assistant, on recent devices; availability depends on region and account. The home screen leans heavily on Amazon content and on paid placements: a large rotating banner at the top, sponsored rows and autoplaying previews. Fire TV is the most ad-forward of the big platforms. You can turn off video and audio autoplay in Settings, and you can limit ad tracking under the privacy options, but you can't remove the sponsored rows.

Which Fire TV fits whom

Choose the 2026 Fire TV Stick 4K if you want the lowest price, your TV does HDR10+ or plain HDR10, and you stick to mainstream apps.

Choose the Fire TV Stick 4K Max if you have a Dolby Vision TV, want the faster Wi-Fi, or need apps from outside Amazon's store.

Choose the Fire TV Cube for hands-free voice control, wired Ethernet or cable box control.

If you don't use Alexa or Prime at all and the ads bother you, a Roku or Google TV device will probably feel less cluttered. The device finder weighs those trade-offs for you.
