Honkai Star Rail 4.5 Livestream Codes, August 26 Launch, ZZZ Tease

Version 4.5 now has a date, and the stream’s biggest tease points beyond it

HoYoverse’s next Honkai: Star Rail update, Version 4.5, is scheduled to launch on August 26, 2026, according to Siliconera, GamersHeroes, and Sportskeeda reports from the Special Program. The patch is titled “To Roll the Stars in Astropolis,” per GamersHeroes, and the stream framed the update around new summer-themed versions of Robin and Aventurine, new events, and a trip to Astropolis.

The immediate player decision is simple but time-sensitive: claim the Honkai Star Rail livestream codes before they expire, then decide how much of Version 4.5 is a pull patch, a progression patch, or a saving patch for your account. The longer-term tension is stranger. Siliconera reports that HoYoverse also confirmed a Honkai Star Rail Zenless Zone Zero crossover for Winter 2026, a tease that arrived near the end of the full 4.5 Special Program after merchandise news. That puts Version 4.5 in the middle of two planning windows: the known August 26 content drop and an announced cross-game event whose mechanics, rewards, and character implications are still unannounced.

The codes are the first thing to handle, because they are short-lived

The three Honkai Star Rail 4.5 livestream codes are 2TKRKAR6YG2X, LSJ9JARPZH33, and YAJQ2TR6ZY2P. Siliconera reports that the three codes collectively grant 300 Stellar Jades. GameRant and Game8 list the individual rewards as 100 Stellar Jades and 50,000 Credits for 2TKRKAR6YG2X, 100 Stellar Jades and five Traveler’s Guides for LSJ9JARPZH33, and 100 Stellar Jades and four Refined Aether for YAJQ2TR6ZY2P.

Polygon reports that the codes expire on August 15 at 11:59 a.m. EDT, which is 8:59 a.m. PDT. That is the practical cutoff players should treat as urgent. These Special Program codes have never been the centerpiece of an account’s economy, but for a turn-based RPG built around character growth, Light Cone investment, and limited banners, 300 Stellar Jades plus leveling materials is still worth taking before the window closes.

Polygon also lays out the redemption routes. Players can redeem codes in-game by opening the menu, tapping the ellipses in the top-right corner, and choosing the redemption code option. The alternative is HoYoverse’s Honkai: Star Rail gift website, where Polygon notes that players need to log in, select the correct server, and have a working Honkai: Star Rail UID tied to the account. If an account has never logged into the game through that HoYoverse account, Polygon says redemption will not work.

The stream timing matters less now than the archive markers players should revisit

GameRant listed the Honkai Star Rail 4.5 Special Program air time as August 14, 2026, at 7:30 a.m. ET, with regional conversions including 4:30 a.m. PT, 12:30 p.m. in London, 7:30 p.m. in Singapore, and 8:30 p.m. in Tokyo. The same report pointed players to the official YouTube livestream and Honkai: Star Rail Twitch channel.

For anyone catching up after the broadcast, Siliconera’s timing notes are more useful than the original countdown. According to Siliconera, the full 4.5 Special Program showed the Sparxie-themed Moondrop merchandise at around the 42:40 mark, with the Zenless Zone Zero and Honkai: Star Rail teaser following at about 43:23. That placement is worth noting because HoYoverse did not fold the crossover into the Version 4.5 banner explanation or event rundown in the cited reports. It appeared as a forward-looking reveal after merchandise discussion, which supports treating it as confirmed for Winter 2026 but separate from the August 26 patch rollout unless HoYoverse later says otherwise.

Siliconera also says the dedicated Version 4.5 trailer begins with story hints before showing the new Aventurine and Robin alternate forms, then teases events including Overdrive: Whirlwind Grand Prix, Minuscule Great Adventure, and Divergent Universe: Arcadian Chronicles near the end. For players trying to prioritize what to watch, that structure matters: story setup first, character showcases next, systems and events last, then the broader crossover tease in the Special Program archive.

Robin and Aventurine drive the banner calendar, but one path detail is disputed

Across the reports, the core banner picture is consistent. Version 4.5 brings new forms for Robin and Aventurine: Robin • Summeretto and Aventurine • Waveflair. Siliconera reports that Summeretto Robin appears when the update starts alongside a Hyacine rerun, while Waveflair Aventurine arrives on September 12, 2026, alongside an Ashveil rerun. Sportskeeda similarly places Robin Summeretto in Phase 1 and Aventurine Waveflair in Phase 2, with Hyacine in the first phase and Ashveil in the second.

Sportskeeda adds reported four-star banner lineups: Gallagher, Qingque, and Dan Heng in Phase 1, then Guinaifen, Hook, and Sampo in Phase 2. That matters for roster planning because players are rarely pulling only for the headline five-star. Four-star overlap can influence whether a banner is efficient for a newer account, a collector, or someone building around a specific elemental or role need.

There is one important source conflict around Aventurine’s classification. Polygon describes Aventurine Waveflair as a Quantum Nihility character. GamersHeroes says Aventurine • Waveflair is Elation: Quantum. Those are different path labels in the cited material, so players should be cautious about treating either as settled from these secondary reports alone. The Robin detail is more aligned: Polygon lists Robin Summeretto as Wind Remembrance, and GamersHeroes lists Robin • Summeretto as Remembrance: Wind.

For a systems-minded player, that uncertainty around Aventurine is not trivia. Path determines Light Cone eligibility and usually frames team role expectations. Until HoYoverse’s own in-game notices, official character pages, or final banner details clarify the discrepancy, it is safer to plan around confirmed timing and character identity rather than pre-farming based on one reported Aventurine path label.

Astropolis and the event slate suggest a patch with both story and repeatable-mode hooks

Sportskeeda reports that Version 4.5 will add the Trailblaze Missions “To Roll the Stars in Astropolis” and “How to Lose Your Way to the Top: The Zero-Dollar Strategy,” along with the new region Astropolis. GamersHeroes also identifies the update title as “To Roll the Stars in Astropolis,” tying the patch’s public framing to that location.

The event list across the reports gives players a better sense of the patch’s shape. Siliconera says Overdrive: Whirlwind Grand Prix, Minuscule Great Adventure, and Divergent Universe: Arcadian Chronicles are teased at the end of the Version 4.5 trailer. Sportskeeda also lists Overdrive: Whirlwind Grand Prix, Minuscule Great Adventure, Planar Fissure, and Realm of the Strange, and says Divergent Universe: Arcadian Chronicles will update that game mode.

That combination points to three separate planning lanes, based on what the sources confirm. Story-focused players have new Trailblaze Missions and a new area. Account-build players should watch Planar Fissure and Realm of the Strange because Sportskeeda identifies them as part of the patch event slate, and those event names are tied to progression activities in the game’s existing structure. Players invested in roguelike or endgame-adjacent systems should pay attention to Divergent Universe: Arcadian Chronicles, because both Siliconera and Sportskeeda call it out by name.

Sportskeeda also reports new Light Cones for Version 4.5: the five-star “Rise and Sing,” described as Robin’s signature, the five-star “Summer Rides the Surf,” described as Aventurine’s signature, and two four-stars, “A Little Gateaway” and “Race to the Horizon.” As with the disputed Aventurine path reporting, final build planning should wait for official in-game stats and descriptions. Names and rarity are useful for budgeting, but they are not enough to judge whether a Light Cone is account-defining, replaceable, or narrowly tuned to one kit.

The Zenless Zone Zero crossover is confirmed for winter, but the usable details are still missing

Siliconera reports that HoYoverse confirmed a Zenless Zone Zero crossover event for Honkai: Star Rail in Winter 2026. The same report notes that the teaser appeared immediately after the Moondrop Sparxie merchandise segment in the full Special Program. It also lists current platform availability: Honkai: Star Rail is available on PS5, PC, and mobile devices, while Zenless Zone Zero is on PS5, Xbox Series X, PC, and mobile devices.

That platform spread creates one of the practical unknowns around the crossover. Zenless Zone Zero has an Xbox Series X version listed by Siliconera, while Honkai: Star Rail does not in the provided source material. None of the cited reports say whether the crossover will include content inside both games, rewards tied to both HoYoverse accounts, a story event, cosmetics, characters, or a limited promotional campaign. The only sourced timing is Winter 2026.

Players should also separate the crossover tease from the Moondrop collaboration shown in the same late-program stretch. Siliconera says the Sparxie Moondrop items include red wireless earphones based on the character, plus an acrylic pendant and acrylic stand. GamersHeroes says the Honkai: Star Rail and Moondrop collaboration will roll out with Sparxie-themed products and online and offline events across multiple regions. Those are merchandise and promotional details, while the Zenless Zone Zero crossover is a separate winter event tease in the cited coverage.

The useful takeaway for progression planning is restraint. Version 4.5 has named banners, dated phases, codes, story missions, events, and Light Cone names. The Honkai Star Rail Zenless Zone Zero crossover has a confirmed season and little else. If you are deciding between Robin Summeretto, Aventurine Waveflair, Hyacine, and Ashveil, the August 26 and September 12 banner information is the concrete data. If you are saving because the idea of a HoYoverse crossover is appealing, that is an expectation-based choice until HoYoverse says what Winter 2026 actually contains.
