Saber, real name Artoria (or Altria) Pendragon, is one of the characters involved in the collaboration between Honkai Star Rail and Fate/stay night Unlimited Blade Works! Check out Saber's release date as a playable HSR character and what we know about her here.
Saber release date in Honkai Star Rail
According to the official announcement from HoYoverse across their social media and HoYoLAB, Saber's release date as a playable Honkai Star Rail character is on July 11, 2025. This coincides with the Honkai Star Rail version 3.4 update. Saber is a 5-star Wind character on the Path of Destruction.

Saber's banner is labeled as a "Special Collaboration Warp" banner and will have a separate pity count to the character banners already in the game. Hers and Archer's banner will "be available over a long period of time," but no exact duration was named. However, we can safely assume that it will last more than the usual three weeks.
The reveal post for Saber tells us much about what's going on in this collaboration. It also tells a little about her character, in case you're not familiar with the Fate/ series.

The solitary Heroic Spirit traverses the long night of fate. The banner of the round table remains unfurled in a dream. Alas, the knight-king of Camelot has yet to reach that ever distant utopia.
Though still a young maiden, she has heeded the call for this most unique iteration of the Holy Grail War. With the Sword in the Stone offering its choice once more, how shall she shatter the illusions of the past?

Saber's real name is Artoria Pendragon, and is Fate's spin on King Arthur from Arthurian legend. Of course, she wields the famed Excalibur.
In Fate/ canon, names are integral to the "Servants," the summoned personalities from various myths, legends, or even history. Their True Names hold power over them, and this is why they instead go by their classes. In Artoria's case, hers is Saber in this specific iteration.
The next thing we learn about is the collab's significance. Fate/'s story beyond Fate/stay night has been largely non-continuous and fragmented. But, the one thing that stays constant across the franchise, including the gacha game Fate/Grand Order, is the presence of a Holy Grail War.
A Holy Grail War is when Servants are summoned by Masters who strive to claim the Holy Grail. We already know that Saber and Archer will be playable units in this collab, but we can expect other servants like Lancer, Caster, Rider, Assassin, or Berserker from Fate/stay night to appear as NPCs.
